Understanding Bacterial Meningitis: A Serious Health Threat

Bacterial meningitis is a severe infection that affects the membranes surrounding the brain and spinal cord. This potentially life-threatening condition requires immediate medical attention, as it can lead to devastating consequences within hours of onset. While most individuals recover with proper treatment, some may experience long-lasting effects, including brain damage, hearing loss, and learning disabilities.

Common Causes of Bacterial Meningitis

Several bacteria can cause meningitis, with the leading culprits in the United States being:

• Streptococcus pneumoniae
• Group B Streptococcus
• Neisseria meningitidis
• Haemophilus influenzae
• Listeria monocytogenes
• Escherichia coli

Mycobacterium tuberculosis, the bacterium responsible for tuberculosis (TB), is a less common cause of bacterial meningitis, often referred to as TB meningitis.

Age-Specific Bacterial Causes

Different age groups are more susceptible to certain types of bacteria:

• Newborns: Group B Streptococcus, S. pneumoniae, L. monocytogenes, E. coli
• Babies and young children: S. pneumoniae, N. meningitidis, H. influenzae, Group B Streptococcus, M. tuberculosis
• Teens and young adults: N. meningitidis, S. pneumoniae
• Older adults: S. pneumoniae, N. meningitidis, H. influenzae, Group B Streptococcus, L. monocytogenes

Risk Factors for Bacterial Meningitis

Certain factors can increase an individual’s risk of contracting bacterial meningitis:

1. Age: Infants are at higher risk compared to other age groups, although anyone can develop the infection.
2. Group settings: Large gatherings, such as college campuses, can facilitate the spread of infectious diseases like meningococcal disease.
3. Medical conditions: Certain health issues, medications, and surgical procedures can elevate the risk of meningitis. For example, HIV infection, cerebrospinal fluid leaks, or the absence of a spleen can increase susceptibility to various types of bacterial meningitis.
4. Occupational exposure: Microbiologists who routinely work with meningitis-causing bacteria face an increased risk.
5. Travel: Visiting specific regions, such as the meningitis belt in sub-Saharan Africa or Mecca during the Hajj and Umrah pilgrimage, can heighten the risk of meningococcal disease.

Transmission of Bacterial Meningitis

The mode of transmission for bacterial meningitis varies depending on the specific pathogen involved. While some bacteria, like L. monocytogenes, can spread through contaminated food, most are transmitted from person to person. It’s crucial to note that individuals can be carriers of these bacteria without exhibiting symptoms, yet still spread them to others.

Common Transmission Routes

• Group B Streptococcus and E. coli: Vertical transmission from mother to baby during childbirth
• H. influenzae, M. tuberculosis, and S. pneumoniae: Respiratory transmission through coughing or sneezing in close proximity
• N. meningitidis: Exchange of respiratory or throat secretions during close contact (e.g., kissing) or prolonged exposure (e.g., living together)
• E. coli and L. monocytogenes: Consumption of contaminated food

Recognizing the Signs and Symptoms of Bacterial Meningitis

Identifying the symptoms of bacterial meningitis is crucial for early intervention. The signs can vary depending on the age of the affected individual and the specific bacteria involved.

General Symptoms in Adults and Older Children

• Sudden high fever
• Severe headache
• Stiff neck
• Sensitivity to light
• Nausea and vomiting
• Confusion or altered mental state
• Seizures

Symptoms in Infants and Young Children

• High fever
• Excessive sleepiness or irritability
• Poor feeding
• Bulging fontanelle (soft spot on the head)
• Unusual posturing, such as arching of the back
• Seizures

Is bacterial meningitis always accompanied by a fever. While a sudden high fever is a common symptom of bacterial meningitis, it’s important to note that not all cases present with fever, especially in the early stages or in individuals with compromised immune systems. Therefore, the absence of fever does not rule out the possibility of meningitis.

The Link Between Bacterial Meningitis and Sepsis

Many of the bacteria responsible for meningitis can also cause sepsis, a life-threatening condition that occurs when the body’s response to infection triggers a chain reaction throughout the body. Sepsis is a medical emergency that can rapidly lead to tissue damage, organ failure, and death if not treated promptly.

Can sepsis develop without meningitis. Yes, sepsis can occur independently of meningitis. While both conditions can be caused by the same bacteria, sepsis is a systemic response to infection that can originate from various sources in the body, not just the central nervous system.

Prevention Strategies for Bacterial Meningitis

Preventing bacterial meningitis involves a combination of vaccination, good hygiene practices, and awareness of risk factors.

Vaccination

Vaccines are available for several types of bacterial meningitis, including:

• Pneumococcal conjugate vaccine (PCV13) and pneumococcal polysaccharide vaccine (PPSV23) for S. pneumoniae
• Meningococcal conjugate vaccine (MenACWY) and serogroup B meningococcal vaccine (MenB) for N. meningitidis
• Hib vaccine for H. influenzae type b

How effective are meningitis vaccines. Meningitis vaccines are highly effective in preventing the specific strains of bacteria they target. For example, the pneumococcal conjugate vaccine (PCV13) has been shown to reduce invasive pneumococcal disease by over 90% in vaccinated individuals. However, it’s important to note that vaccines do not protect against all types of bacterial meningitis.

Hygiene and Lifestyle Practices

• Practice good hand hygiene by washing hands frequently with soap and water
• Avoid sharing personal items such as toothbrushes, eating utensils, or drinking glasses
• Maintain a healthy lifestyle to support a strong immune system
• Cover your mouth and nose when coughing or sneezing
• If you’re pregnant, take precautions to avoid Listeria infection by avoiding high-risk foods

Special Considerations for High-Risk Groups

Pregnant Women and Newborns

Pregnant women are at increased risk of Listeria infection, which can lead to serious complications for both the mother and the baby. Symptoms in pregnant women may be mild, resembling flu-like symptoms, but the consequences for the fetus can be severe, including miscarriage, stillbirth, premature delivery, or life-threatening infection of the newborn.

To reduce the risk of Listeria infection, pregnant women should:

• Avoid soft cheeses made from unpasteurized milk
• Avoid raw or undercooked meat, poultry, and seafood
• Thoroughly wash raw fruits and vegetables before eating
• Avoid deli meats and hot dogs unless heated to steaming hot

Group B Streptococcus can be passed from mother to baby during delivery. To prevent this, pregnant women are typically screened for Group B Strep between 35-37 weeks of pregnancy. If positive, antibiotics are administered during labor to protect the newborn.

Travelers

Individuals traveling to regions with higher rates of meningococcal disease or tuberculosis should take additional precautions:

• Consult a healthcare provider about necessary vaccinations before travel
• Consider meningococcal vaccination if traveling to the meningitis belt in sub-Saharan Africa or participating in the Hajj pilgrimage
• Avoid close contact with known TB patients in crowded, enclosed environments

Diagnosis and Treatment of Bacterial Meningitis

Early diagnosis and treatment of bacterial meningitis are crucial for improving outcomes and reducing the risk of complications.

Diagnostic Procedures

• Lumbar puncture (spinal tap) to collect cerebrospinal fluid for analysis
• Blood cultures to identify the causative bacteria
• Imaging studies such as CT or MRI scans to detect swelling or inflammation

How long does it take to diagnose bacterial meningitis. The initial diagnosis of bacterial meningitis can be made within hours through a lumbar puncture and analysis of cerebrospinal fluid. However, identifying the specific bacteria responsible may take 24-48 hours as laboratory cultures grow.

Treatment Approaches

Treatment for bacterial meningitis typically involves:

• Intravenous antibiotics administered as soon as meningitis is suspected, even before the specific cause is identified
• Corticosteroids to reduce inflammation and swelling in the brain
• Supportive care, including fluids, pain management, and fever reduction

The choice of antibiotics may be adjusted once the specific bacterium is identified through laboratory tests.

Long-Term Consequences and Follow-Up Care

While many individuals recover fully from bacterial meningitis, some may experience long-term complications that require ongoing care and support.

Potential Long-Term Effects

• Hearing loss
• Vision problems
• Memory and concentration difficulties
• Balance and coordination issues
• Learning disabilities
• Seizures
• Kidney problems

What percentage of bacterial meningitis survivors experience long-term effects. The incidence of long-term effects varies depending on factors such as the causative bacteria, the patient’s age, and how quickly treatment was initiated. Studies suggest that approximately 10-20% of survivors may experience some form of long-term complication, with hearing loss being one of the most common.

Follow-Up Care

Survivors of bacterial meningitis should receive comprehensive follow-up care, which may include:

• Regular hearing tests
• Neurological evaluations
• Cognitive assessments
• Psychological support
• Educational support for children who experience learning difficulties

Early intervention and ongoing support can significantly improve the quality of life for those affected by long-term complications of bacterial meningitis.

Research and Future Directions in Bacterial Meningitis Prevention and Treatment

Ongoing research in the field of bacterial meningitis aims to improve prevention strategies, diagnostic techniques, and treatment options.

Vaccine Development

Scientists are working on developing new vaccines and improving existing ones to provide broader protection against various strains of meningitis-causing bacteria. This includes efforts to create universal vaccines that could protect against multiple strains simultaneously.

Rapid Diagnostic Tools

Research is underway to develop faster and more accurate diagnostic tests that can identify the specific cause of meningitis within hours, allowing for more targeted treatment approaches.

Novel Treatment Approaches

Investigators are exploring new therapeutic strategies, including:

• Targeted antibiotics that can penetrate the blood-brain barrier more effectively
• Immunomodulatory therapies to regulate the immune response and reduce inflammation
• Neuroprotective agents to minimize brain damage during the acute phase of the infection

What are the most promising areas of research in bacterial meningitis treatment. Some of the most promising areas include the development of rapid point-of-care diagnostic tests, novel antibiotics with enhanced penetration of the blood-brain barrier, and adjunctive therapies that can modulate the immune response to reduce inflammation-induced damage. Additionally, research into the long-term effects of meningitis and strategies to improve rehabilitation outcomes is gaining importance.

Global Health Initiatives

International efforts are focusing on improving access to vaccines and medical care in regions with high rates of bacterial meningitis, particularly in the African meningitis belt. These initiatives aim to reduce the global burden of the disease through vaccination campaigns, improved surveillance, and strengthening of healthcare systems.

By advancing our understanding of bacterial meningitis and developing new tools for prevention, diagnosis, and treatment, researchers hope to further reduce the incidence and impact of this serious infection worldwide.

Bacterial Meningitis | CDC

Bacterial meningitis is serious. Some people with the infection die and death can occur in as little as a few hours. However, most people recover from bacterial meningitis. Those who do recover can have permanent disabilities, such as brain damage, hearing loss, and learning disabilities.

Causes

Several types of bacteria can cause meningitis. Leading causes in the United States include

• Streptococcus pneumoniae
• Group B Streptococcus
• Neisseria meningitidis
• Haemophilus influenzae
• Listeria monocytogenes
• Escherichia coli

Mycobacterium tuberculosis, which causes tuberculosis or TB, is a less common cause of bacterial meningitis (called TB meningitis).

Many of these bacteria can also be associated with another serious illness, sepsis. Sepsis is the body’s extreme response to infection. It is a life-threatening medical emergency.  Sepsis happens when an infection triggers a chain reaction throughout your body. Without timely treatment, sepsis can quickly lead to tissue damage, organ failure, and death.

Some causes of bacterial meningitis are more likely to affect certain age groups:

• Newborns: Group B Streptococcus, S. pneumoniae, L. monocytogenes, E. coli
• Babies and young children: S. pneumoniae, N. meningitidis, H. influenzae, group B Streptococcus, M. tuberculosis
• Teens and young adults: N. meningitidis, S. pneumoniae
• Older adults: S. pneumoniae, N. meningitidis, H. influenzae, group B Streptococcus, L. monocytogenes

Risk Factors

Certain factors increase a person’s risk for getting bacterial meningitis. These risk factors include:

• Age: Babies are at increased risk for bacterial meningitis compared to people in other age groups. However, people of any age can develop bacterial meningitis. See section above for which bacteria more commonly affect which age groups.
• Group setting: Infectious diseases tend to spread where large groups of people gather. For example, college campuses have reported outbreaks of meningococcal disease, caused by N. meningitidis.
• Certain medical conditions: Certain medical conditions, medications, and surgical procedures put people at increased risk for meningitis. For example, having an HIV infection or a cerebrospinal fluid leak, or not having a spleen can increase a person’s risk for several types of bacterial meningitis.
• Working with meningitis-causing pathogens: Microbiologists routinely exposed to meningitis-causing bacteria are at increased risk for meningitis.
• Travel: Travelers may be at increased risk for meningococcal disease, caused by N. meningitidis, if they travel to certain places, such as:
  • The meningitis belt in sub-Saharan Africa, particularly during the dry season
  • Mecca during the annual Hajj and Umrah pilgrimage

In many countries, TB is much more common than in the United States. Travelers should avoid close contact or prolonged time with known TB patients in crowded, enclosed environments (for example, clinics, hospitals, prisons, or homeless shelters).

How It Spreads

Certain germs that cause bacterial meningitis, such as L. monocytogenes, can spread through food. But most of these germs spread from one person to another.

How people spread the germs often depends on the type of bacteria. It is also important to know that people can have these bacteria in or on their bodies without being sick. These people are “carriers.” Most carriers never become sick, but can still spread the bacteria to others.

Here are some of the most common examples of how people spread each type of bacteria to each other:

• Group B Streptococcus and E. coli: Mothers can pass these bacteria to their babies during birth.
• H. influenzae, M. tuberculosis, and S. pneumoniae: People spread these bacteria by coughing or sneezing while in close contact with others, who breathe in the bacteria.
• N. meningitidis: People spread these bacteria by sharing respiratory or throat secretions (saliva or spit). This typically occurs during close (coughing or kissing) or lengthy (living together) contact.
• E. coli: People can get these bacteria by eating food prepared by people who did not wash their hands well after using the toilet.

People usually get sick from E. coli and L. monocytogenes by eating contaminated food.

Signs and Symptoms

Being pregnant increases a person’s risk of getting a Listeria infection  (L. monocytogenes). Pregnant people with a Listeria infection may not have any symptoms or may only have a fever and other flu-like symptoms, such as fatigue and muscle aches. However, infection during pregnancy can lead to miscarriage, stillbirth, premature delivery, or life-threatening infection of the newborn, including meningitis. Find out which foods are more likely to contain Listeria and steps you can take to protect your and your baby’s health.

Pregnant women can pass group B Streptococcus (group B strep) to their baby during delivery. Newborns infected with group B strep can develop meningitis or other serious infections soon after birth. Talk with your doctor or midwife about getting a group B test when you are 36 through 37 weeks pregnant. Doctors give antibiotics (during labor) to women who test positive in order to prevent infections in newborns.

Meningitis symptoms include sudden onset of

• Fever
• Headache
• Stiff neck

There are often other symptoms, such as

• Nausea
• Vomiting
• Photophobia (eyes being more sensitive to light)
• Altered mental status (confusion)

Newborns and babies may not have, or it may be difficult to notice the classic symptoms listed above. Instead, babies may

• Be slow or inactive
• Be irritable
• Vomit
• Feed poorly
• Have a bulging fontanelle (the “soft spot” on a baby’s head)
• Have abnormal reflexes

If you think your baby or child has any of these symptoms, call the doctor right away.

Typically, symptoms of bacterial meningitis develop within 3 to 7 days after exposure; note, this is not true for TB meningitis, which can develop much later after exposure to the bacteria.

People with bacterial meningitis can have seizures, go into a coma, and even die. For this reason, anyone who thinks they may have meningitis should see a doctor as soon as possible.

Diagnosis

If a doctor suspects meningitis, they will collect samples of blood or cerebrospinal fluid (fluid near the spinal cord). A laboratory will test the samples to see what is causing the infection. Knowing the specific cause of meningitis helps doctors treat it.

Treatment

Doctors treat bacterial meningitis with a number of antibiotics. It is important to start treatment as soon as possible.

Prevention

Vaccination

Vaccines are the most effective way to protect against certain types of bacterial meningitis. There are vaccines for 4 types of bacteria that can cause meningitis:

• Meningococcal vaccines help protect against N. meningitidis
• Pneumococcal vaccines help protect against S. pneumoniae
• Haemophilus influenzae serotype b (Hib) vaccines help protect against Hib
• Bacille Calmette-Guérin vaccine helps protect against tuberculosis disease, but is not widely used in the United States

Make sure you and your child are vaccinated on schedule.

Like with any vaccine, these vaccines do not work 100% of the time. The vaccines also do not protect against infections from all the types (strains) of each of these bacteria. For these reasons, there is still a chance vaccinated people can develop bacterial meningitis.

Prophylaxis

When someone has bacterial meningitis, a doctor may recommend antibiotics to help prevent people around the patient from getting sick. Doctors call this prophylaxis. CDC recommends prophylaxis for:

• Close contacts of someone with meningitis caused by N. meningitidis
• Household members of someone with a serious Hib infection when the household includes one or more people at increased risk of Hib based on age, vaccination status, and/or immunocompromising conditions

Doctors or local health departments recommend who should get prophylaxis.

Healthy Pregnancy Practices

Pregnant women should talk to their doctor or midwife about getting tested for group B Streptococcus. Women receive the test when they are 36 through 37 weeks pregnant. Doctors give antibiotics (during labor) to women who test positive in order to prevent passing group B strep to their newborns.

Pregnant women can also reduce their risk of meningitis caused by L. monocytogenes. Women should avoid certain foods during pregnancy and safely prepare others.

Healthy Habits

You can also help protect yourself and others from bacterial meningitis and other health problems by maintaining healthy habits:

• Don’t smoke and avoid cigarette smoke as much as possible
• Get plenty of rest
• Avoid close contact with people who are sick
• Wash your hands often with soap and water (use hand sanitizer if soap and water aren’t available)
• Cover your mouth and nose with a tissue when you cough or sneeze (use your upper sleeve or elbow if a tissue isn’t available)

These healthy habits are especially important for people at increased risk for disease, including:

• Young babies
• Older adults
• People with weak immune systems
• People without a spleen or a spleen that doesn’t work the way it should

Abstract

Background:

Death from bacterial meningitis is rarely attributed to the actual event causing death. The present study therefore categorized and characterized the cause and time of death due to bacterial meningitis.

Methods:

In a cohort of patients > 15 years of age with community acquired bacterial meningitis the medical records were reviewed, and a clinical cause of death categorized into six main categories: 1) CNS complications, 2) Systemic complications, 3) Combination of systemic and CNS complications, 4) Sudden death, 5) Withdrawal of care, or 6) Unknown.

Results:

We identified 358 patients of which 84 (23%) died in-hospital. Causes of death were ascribed to CNS complications in 43%, Systemic complications in 39%, Combined CNS and systemic complications in 4%, Sudden death in 7% and withdrawal of care in 5%. Brain herniation, circulatory failure, intractable seizures and other brain injury were the most common specific causes of death within 14 days from admission (55%).

Conclusion:

Fatal complications due to the primary infection – meningitis – is most common within 14 days of admission. The diversity of complications causing death in meningitis suggest that determining the clinical cause of death is essential to the evaluation of novel treatment strategies.

Meningococcus – a terrible infection that can literally lead to death in a day or to such meningitis, about which the people say “had been ill and become a fool. ”

The most notorious outbreaks of meningoccal infection in the last year occurred among employees of the popular marketplace. At the end of 2022, 11 people became infected and fell ill at the Ozon warehouse in Istra near Moscow. At the same time, according to Fontanka, an employee of the St. Petersburg Ozone died in the Botkin hospital – a girl who had come to St. Petersburg from Murmansk. Now seven people have fallen ill, of which two Ozon employees in Yekaterinburg have died. With the help of doctors, Fontanka figured out why people die from this bacterial infection in general in our time and whether it is possible to protect themselves from it.

According to Fontanka, 10 Petersburgers with meningitis are currently being treated in the city’s Botkin hospital. Almost every day, an ambulance delivers patients with such a diagnosis. But these are only those who have the so-called primary meningitis – serous, tick-borne and yes, meningococcal. With the secondary, they go to ordinary, non-infectious hospitals. For example, bacterial endocarditis can cause embolic meningitis. Such patients are hospitalized in cardiosurgical departments of general hospitals. When otitis or sinusitis as a complication of a common cold becomes the cause of bacterial meningitis, they are dealt with by ENT doctors in multidisciplinary hospitals.

As Mikhail Komarov, head of the ENT department of the City Hospital No. 26, explained, when a patient develops secondary meningitis due to an ear or nose disease (there are 2–3 such patients per month), a surgical intervention is performed to remove the primary focus infections: “If by this time an abscess has not formed in the brain, then the patient is treated with antibiotics that penetrate the blood-brain barrier and destroy the infection in the cerebrospinal fluid spaces and brain tissues. The probability of dying from this group of diseases is very high and is 10%, no less than the possibility of remaining disabled with a deep neurological deficit. These outcomes may have predisposing causes – old age, diseases of the cardiovascular system, immune deficiency, and others.

Otorhinolaryngologist Komarov emphasizes: secondary bacterial meningitis is not associated with meningococcal infection, the treatment of patients with which is carried out only in an infectious diseases hospital with strict adherence to anti-epidemic measures.

In a specialized hospital – the Botkin hospital – they told Fontanka that in recent years there have been few patients with meningococcal infection – the Neisseria meningitidis bacterium, no more than 5-10 people a year. In general, there have been no outbreaks of meningococcal infection in St. Petersburg for a long time, the last one happened more than 15 years ago.

The disease is dangerous because it can proceed in different ways, for example, with meningococcemia – bleeding in the adrenal glands and with septic shock. And this is deadly: from the appearance of the first symptoms to the most severe condition, they can develop in a matter of hours. If you miss the moment when you can help avoid serious complications, then a person will either become disabled or die.

Information:

In 2021, 10 children were registered in St.

In 2022, 17 people were registered with meningococcal infection, including 9 children under the age of 17. One person died.

In 2023, 17 cases have already been registered, including three children under 17 years old. One person died.

Meningococcal infection became more active after covid, when the coronavirus weakened, and other infections began to return. More precisely, meningococcus did not go anywhere, but behaved with restraint. It is always around us – in the air, especially in humid regions, which include St. Petersburg. In a “dormant” state, meningococcus lives in the nasopharynx in 10-15% of the population – the risk of developing the disease increases if someone’s immunity is sharply weakened. It happens that it sits in the nose and immediately dies when the immune system is strong, it happens that it takes root in it and nasopharyngitis develops, the disease proceeds like an acute respiratory viral infection and this is where it all ends. And in a weakened person, it penetrates through the nose into the brain and develops severe generalized meningitis.

Help

The three main symptoms of meningococcal meningitis are:

9 0013 1. Chills and rapid temperature increase above 38-39 degrees.

2. Extremely severe, unbearable headache for which pain pills do not help.

3. Hyperesthesia – increased sensitivity to light, sounds, touch.

Meningococcus is a cyclically recurring infection, and periods of “lull” are just 15–20 years. Therefore, now infectious disease specialists are wary of information about the emerging diseases of generalized meningoccal infection.

Marina Dessau, Head of the Department of Infectious and Parasitic Diseases at the City Polyclinic No. 122, explains: “The cyclical activity of meningococcal infection suggests that the incidence increases strongly every 15–20 years. And the larger the gap – the “quiet period”, the more aggressively this microbe will behave in a year of high activity.”

In the outpatient network, physicians typically deal with the aftermath of a generalized infection or when a patient is reported to be infected with Neisseria meningitidis. “Doctors work in the “center”, examine those who have been in contact with the infected. But it is still difficult to identify the source if there are no clinical manifestations, says Marina Dessau. – There are many carriers of this infection, each of them can potentially become its distributor. But not everyone to whom it is transmitted will develop a severe clinical picture of the disease: it is easiest to infect a young child or a debilitated elderly person, and they are also at high risk of a severe course of the disease.

Information:

According to statistics, if the diagnosis is made within the first 12 hours from the onset of the disease, the risk of death is reduced to 0.7-1.5%. If treatment was started in a day – up to 2-4%, after two days – 5-6%, after three or four days – 15-18%. Without treatment, 85% of patients die, 15% remain severely disabled.

However, when there are symptoms, it is rare to diagnose the disease at an early stage. Because meningococcal meningitis begins with signs of a common cold. It is possible to differentiate with a respiratory infection with appropriate vigilance three days after the onset of the disease. In a person with SARS, the symptoms should decrease, with meningococcus they increase, including the temperature rises, the headache becomes more intense. But even this does not always make it possible to distinguish meningococcal infection from a respiratory virus. It is good if the patient is hospitalized before meningococcemia and the appearance of a rash on the body. But even in these cases, patients are difficult and long treated in the hospital. And when they return home, they are observed in outpatient medical facilities by local therapists (pediatricians) and neurologists, who work with complications that depend on the severity of the disease — hearing loss, visual impairment, memory problems, paresis and paralysis.

Doctors say that the best prevention is sun and water, vitamins, and with them – good immunity. But it is not exactly. Only vaccination gives 100% certainty. An expensive vaccine has recently been included in the National Immunization Schedule.

Meningococcal bacterium Neisseria meningitidis, which causes severe forms of generalized sepsis, can be of different groups, a quarter of registered cases occur in a representative of serogroup B, against which the Bexero vaccine (GSK, UK) protects. She is not in St. Petersburg today.

It is possible to vaccinate with the Menactra vaccine (Sanofi, USA), which protects against other serotypes.

As the infectious disease specialist Marina Dessau explained, free of charge, within the framework of the National Immunization Calendar, vaccination is carried out only for children, adults – according to indications, for example, contacts, as well as those who live in crowded groups, for example, military personnel in barracks.

The optimism that inspires the rapid development and prospects for the use of neural networks, virtual and augmented realities, is constrained by a number of unresolved problems. If neural networks are spreading faster and faster, then the recent boom in AR and VR technologies has somehow subsided. The Fontanka round table participants said that the possibilities of all these technologies are almost limitless, and only a small part has been mastered.

a disease that kills in minutes traveled from Petersburg to Moscow. Her mother made this story public so that everyone knew about the disease that kills in minutes.

Five-year
Muscovite Yana could not be saved by the doctors of both capitals – she fell ill when
traveled from Petersburg to Moscow. Her mom made this story public for
so that everyone knows about the disease that kills in minutes.

“Maximum repost”

mother Yana began the retelling of her tragedy with words. She is convinced that if all
parents knew the symptoms of meningococcal infection, then many children could be
save.

“I
I am writing this post so that all around the parents of children of any age are
vigilant, did not expect irreversible consequences: pain in the head, sore throat,
vomiting, high fever can be not just SARS, but a disease with
fatal… due
there is no information on this disease in our country, vaccination is not
obligatory and paid,” the woman wrote on the social network.

How
Yana said that on January 7, 2018, she was returning with her daughter after a vacation in
Petersburg to Moscow. A couple of hours before the train left, my daughter complained about
chills, after a couple of hours, already on the train, the temperature rose to 39. 5. All the time
asked for a drink. The temperature was brought down for a while, but it again rapidly
rose to 40, 40.5 degrees. The girl began to rave.

Chief
train called an ambulance to a stop in Tver. Doctors gave an injection of lytic mixture,
but they did not insist on hospitalization, saying that they did not see anything fatal.
The family moved on. Mom notes that the child was lying on the train all the time
on his side and complained of pain in his leg at the slightest touch. Then came
spots on the skin.

Promised
there were no ambulances at the station in the capital; doctors at the station first-aid post
also did not notice anything extraordinary at first, and only after Yana
said that her daughter complains of pain in her leg, the doctor began to check exactly
symptoms of meningitis. The girl was rushed to the hospital, but after a few
minutes she died.

Doctors
did everything possible. For people who ask. We didn’t get sick
colds. Everything, absolutely all vaccinations were done. Take care of family and friends!
Be safe! Check and recheck the symptoms! – Eva’s mother writes in
social network. – Our daughter was loved by her parents and all the people around her. She
was happy, not childishly sensible and dreamed of being a princess, having
magic wand and make people happy… and do gymnastics on
air canvases … “.

B
the same day in the same hospital in Moscow a few hours earlier from the same
infection, 11-month-old Alfiya died.

Meningitis cycle – 35-40 years

Last
times an outbreak of meningococcal infection in St. Petersburg and the neighboring 47 region
recorded in autumn 2015. In the Smolny Newsletter
it is specified that several children in Sestroretsk fell ill with serous meningitis.
Doctors did their best to reassure the population, explaining that there was no epidemic
No. Clinical manifestations of “serous meningitis” were found in 9children,
All of them were promptly hospitalized and treated in the hospital. However,
then we are talking about one of the subtypes of a terrible infection – serous meningitis, which
must be distinguished from the more dangerous meningococcal bacterial meningitis.
Serous meningitis with timely help is quite easily cured without
consequences for the body. Petersburg for the last decades has not been
recorded deaths caused by serous meningitis. Wherein
infectious disease doctors note that the latest epidemic rise in the incidence
meningitis in Russia was at 1980s, and its cycle is 35-40 years.
This means that the incidence is likely to increase in the coming years.

There is no outbreak of meningitis in St. Petersburg

Frightened
With terrible news from Moscow, Petersburgers started talking about an outbreak of meningitis. “PD”
appealed directly to the Office of Rospotrebnadzor, the Health Committee
Smolny and to the chief pediatric infectious disease specialist of the city Vladimir Timchenko for
explanations and statistics.

B
The Office of Rospotrebnadzor was assured that there was no outbreak, no outbreaks
morbidity was not recorded, the incidence does not exceed
average scores.

B
The Health Committee also clarified that there was no talk of any epidemics
goes and reported that in 2016, three children died from meningitis in St. Petersburg,
in 2017 – five. These are certainly tragedies, but not exceeding the usual
mortality rates from this disease.

Main
pediatric infectious disease specialist Vladimir Timchenko suggested that rumors about an alleged
outbreak is probably related to the fact that on January 30 and 31 in St. Petersburg
the Russian scientific and practical conference “Meningococcal infection:
old experience and new threats. Other bacterial and viral lesions of the nervous system
systems”, organized by the Research Institute of Children’s Infections. It will report the results
study of meningococcal infection by specialists from leading medical institutions
Russia, the experience of diagnostics, prevention and treatment of diseases,
caused by meningococcus.

“This is
an absolutely planned event, in no way connected with the cases in Moscow.
I responsibly declare that there is no increase in the incidence of meningitis in St. Petersburg,”
– said the chief pediatric infectious disease specialist.

He
also said that in the fight against such a dangerous and serious disease as
meningococcal infection is the only reliable means of prevention is
vaccination. Meningitis vaccinations are not
included in the National Immunization Calendar, since the issue of inclusion
a certain vaccination is decided based on the number of cases per 100 thousand
population (for inclusion in the calendar, the threshold must exceed two cases per 100
thousand population. In meningococcal infection – 0.3 cases per 100 thousand), but
You can and should do it on your own initiative. Now the world is producing
about 20 types of vaccines against meningococcal meningitis.

“Need
understand that the vaccine will either completely protect the child from infection, or help
recover with minimal complications. This is especially important in the case of
meningococcal infection, in which the probability of death is high,
noted the chief pediatric infectious disease specialist of St. Petersburg.

What you need to know about meningitis

Meningococcal
(bacterial) meningitis is a severe form of meningitis, a serious infection of the small intestine
membranes surrounding the brain and spinal cord. More common for bacterial meningitis
affects small children aged 0 to 5 years. The chance of getting sick depends
from immunity. Prerequisites for the disease may be constant contact of people
indoors, high temperature and humidity, increased
concentration of carbon dioxide and hydrogen sulfide.

Feature
of this infection is that from the manifestation of the first symptoms to the most severe condition
a few hours or even minutes pass – often a person does not even have time to get there
to the medical facility. If you are late with treatment, then the victim is waiting for either
disability or death.

If
diagnosed within the first 12 hours of onset, the risk of death
outcome is reduced to 0.7-1.5%. If treatment was started in a day – up to 2 – 4%,
after two days – 5 – 6%, after three or four days – 15-18%. No treatment 85%
sick people die, 15% remain severely disabled.

Meningococcal symptoms

Hatching
the period ranges from 2 to 10 days (usually 4-6 days).
