Post-viral fatigue refers to lingering feelings of extreme tiredness after a viral illness. Doctors are still trying to learn more about it.

Fatigue is an overall feeling of tiredness or exhaustion. It’s completely normal to experience it from time to time. But sometimes it can linger for weeks or months after you’ve been sick with a viral infection, such as the flu. This is known as post-viral fatigue.

Read on to learn more about the symptoms of post-viral fatigue and what you can do to manage them.

The main symptom of post-viral fatigue is a significant lack of energy. You might also feel exhausted, even if you’ve been getting plenty of sleep and resting.

Other symptoms that can accompany post-viral fatigue include:

  • concentration or memory problems
  • sore throat
  • headache
  • swollen lymph nodes
  • unexplained muscle or joint pain

Post-viral fatigue seems to be triggered by a viral infection. In learning about your condition, you might come across information about chronic fatigue syndrome (CFS). This is a complex condition that causes extreme tiredness for no clear reason. While some consider CFS and post-viral fatigue to be the same thing, post-viral fatigue has an identifiable underlying cause (a viral infection).

Viruses that seem to sometimes cause post-viral fatigue include:

  • Epstein-Barr virus
  • Human herpes virus 6
  • human immunodeficiency virus
  • enterovirus
  • rubella
  • West Nile virus
  • Ross River virus

Experts aren’t sure why some viruses lead to post-viral fatigue, but it may be related to:

  • an unusual response to viruses that can remain latent within your body
  • increased levels of proinflammatory cytokines, which promote inflammation
  • nervous tissue inflammation

Learn more about the connection between your immune system and inflammation.

Post-viral fatigue is often hard to diagnose because fatigue is a symptom of many other conditions. It may take some time to rule out other potential causes of your fatigue. Before seeing a doctor, try to write down a timeline of your symptoms. Make a note of any recent illnesses, when your other symptoms went away, and how long you’ve felt fatigued. If you see a doctor, make sure to give them this information.

They’ll likely start by giving you a thorough physical exam and asking about your symptoms. Keep in mind that they might also ask about any mental health symptoms you have, including those of depression or anxiety. Ongoing fatigue is sometimes a symptom of these.

A blood and urine test can help to rule out common sources of fatigue, including hypothyroidism, diabetes, or anemia.

Other tests that can help to diagnose post-viral fatigue include:

  • an exercise stress test to rule out cardiovascular or respiratory conditions
  • a sleep study to rule out sleep disorders, such as insomnia or sleep apnea, which could be affecting the quality of your sleep

Experts don’t fully understand why post-viral fatigue happens, so there aren’t any clear treatments. Instead, treatment usually focuses on managing your symptoms.

Managing the symptoms of post-viral fatigue often includes:

  • taking over-the-counter pain relievers, such as ibuprofen (Advil), to help with any lingering pain
  • using a calendar or organizer to help with memory or concentration issues
  • reducing daily activities to conserve energy
  • energizing relaxation techniques, such as yoga, meditation, massage therapy, and acupuncture

Post-viral fatigue can be extremely frustrating, especially if you’ve already been dealing with a viral infection. This, combined with the limited information about the condition, can make you feel isolated or hopeless. Consider joining a group of others experiencing similar symptoms, either in your local area or online.

The American Myalgic Encephalomyelitis and Chronic Fatigue Syndrome Society offers a variety of resources on their website, including lists of support groups and advice on how to talk to your doctor about your condition. The Solve ME/CFS also has many resources.

Recovery from post-viral fatigue varies from person to person, and there’s no clear timeline. Some recover to the point where they can return to all of their daily activities after a month or two, while others continue to have symptoms for years.

According to a small 2017 study in Norway, getting an early diagnosis may improve recovery. A better prognosis is often observed for people that receive an early diagnosis. Lower recovery rates are associated with people who have had the condition for a longer period of time.

If you think you might have post-viral fatigue, try to see a doctor as soon as possible. If you have limited access to healthcare and live in the United States, you can find free or low-cost health centers here.

Post-viral fatigue refers to lingering feelings of extreme tiredness after a viral illness. It’s a complex condition that experts don’t fully understand, which can make diagnosis and treatment difficult. However, there are several things that can help to manage your symptoms. You may have to try a few things before you find something that works.

Symptoms of acute respiratory infections and SARS. Treatment of Protracted Colds

ARVI is an acute respiratory viral disease, a disease of a viral nature that affects the respiratory tract. ARI is an acute respiratory disease or any inflammatory disease of the respiratory tract. Few of us can boast of the absence of a meeting with these ailments.

In the everyday world we are constantly surrounded by viruses, protozoa, bacteria, fungi. The human body is a place for the reproduction and existence of these life forms. Viruses cannot reproduce in the external environment, since they need a cell; Bacteria, fungi, protozoa can survive in the external environment, but the most comfortable place for their life and reproduction is, no matter how sad it is to admit, our body. When these life forms enter our body, they multiply and cause a respiratory infection.

The human body has a high susceptibility especially to viruses. SARS and ARI are spread by airborne droplets. The source of infection is a sick person who remains contagious for 2-3 days from the onset of the disease, especially when an increase in body temperature is recorded.

You should urgently see a general practitioner if you have:

  • Increased body temperature above 38.0°C
  • Fever
  • Severe general weakness
  • There is a severe headache, mainly in the temporal and frontal regions
  • Lachrymation, pain in the eyes, especially when moving the eyeballs
  • Lachrymation, pain in the eyes, especially when moving the eyeballs
  • Photophobia
  • Muscle and joint pain
  • Painful, hacking cough, chest pain when coughing, streaks of blood appeared in sputum
  • Hoarseness of voice appeared

SARS or acute respiratory infections? What are the symptoms of ARVI and ARI?

It is a very common misconception that ARVI and ARI are one and the same. Of course, there are common signs, but there are also differences in the etiological factor and in clinical manifestations.

The causative agent that causes ARVI is caused by viruses. ARI is caused by viruses, bacteria, fungi, and protozoa.
Onset of the disease Gradual onset, begins with the onset of malaise, weakness. A sharp increase in body temperature up to 38 0 C.
Increasing symptoms The first signs are implicit, the presence of a prodromal period: weakness, headache, malaise. There is an increase in symptoms and their severity for 2-3 days. Persistence of symptoms, without increasing their severity.
The height of the disease It occurs on the 3rd-4th day: fever, pronounced acute runny nose, nasal congestion, sneezing, pain, sore throat, increased headache, general weakness. There is no peak period of the disease, the intensity of symptoms persists in one pore.
Runny nose, conjunctivitis, cough Pronounced. May be absent or not very pronounced.
Disease duration 5-7 days, in the absence of complications in the form of a secondary infection. Manifestations of the disease persist for a long period of time, about two weeks (if the patient does not take antibiotic therapy).
Characteristic changes in the blood test Lymphocytosis, monocytosis Neutrophilia, shift of the leukocyte formula to the left.
Complications Uncommon, but not to be neglected: tonsillitis, tracheitis, laryngitis, bronchitis, otitis media, meningitis, glomerulonephritis, bronchitis. Frequent. Otitis, sinusitis, bronchitis, pneumonia.

IS SARS DANGEROUS?

Any disease can lead to complications.

Complications of acute respiratory infections and acute respiratory viral infections can be: on the part of the respiratory organs – bronchitis, pneumonia, tracheitis. From the ENT organs – laryngitis, rhinitis, sinusitis, frontal sinusitis, otitis, sinusitis. From the side of the central nervous system – encephalitis, meningitis. From the excretory system – glomerulonephritis.

The development of complications depends on the state of the body’s immunity, the age of the patient: children and the elderly, often ill people, are more vulnerable and more difficult to tolerate a respiratory infection.

Complications can be avoided if, at the first symptoms, you immediately seek medical help from a qualified general practitioner who will make a diagnosis and select the correct and individual treatment regimen.

“Acute respiratory viral infection is not as bad as its complications.”

PREVENTION OF ALL VIRAL RESPIRATORY DISEASES AND INFLUENZA got off easy runny nose and cough? Why does someone lie for two weeks with antibiotics with difficulty recovering from complications, and someone – 3-4 days and in the ranks?

Of course, there are a number of factors that affect the frequency and depth of respiratory diseases.

Good immunity is a guarantee that all viruses, bacteria, fungi, protozoa, even if they enter the body, will not cause illness. What should be done to keep the immune system in order?

  • Proper nutrition – a healthy diet without fatty, fried, smoked canned foods.
  • Healthy lifestyle – avoid smoking, alcohol and other bad habits.
  • Compliance with the daily routine – night sleep up to 6-8 hours.
  • No stress.

The number of viruses – the onset of the disease is strongly dependent on the number of pathogens that have entered the body. The more viruses that have entered the body, the more likely the onset of the disease is. To avoid this, first of all, contact with a sick person should be avoided, since transmission occurs by airborne droplets. Ventilate the room more often, especially during the period.

The team of the Healthy Motherland Medical Center wishes you and your loved ones to be healthy, have strong immunity and good mood!

signs, symptoms, treatment and prevention

Influenza is a severe viral infection that affects men, women and children of all ages and nationalities. Influenza epidemics happen every year, usually during the cold season. In terms of the number of cases in the world, influenza and SARS rank first, the share in the structure of infectious diseases reaches 95%.

Influenza and SARS, gradually undermining health, reduce the average life expectancy of a person by several years. In severe cases of influenza, irreversible damage to the cardiovascular system, respiratory organs, and central nervous system often occurs, provoking heart and vascular diseases, pneumonia, tracheobronchitis, and meningoencephalitis.

Influenza collects the greatest victims among the elderly population groups suffering from chronic diseases.

The influenza virus is very easily transmitted:

  • The most common route of transmission is airborne.
  • It is also possible that the household route of transmission, for example, through household items.

When coughing, sneezing, talking, particles of saliva, mucus, sputum with pathogenic microflora, including influenza viruses, are ejected from the nasopharynx of a patient or a virus carrier. An infected zone is formed around the patient with a maximum concentration of aerosol particles. The range of their scattering usually does not exceed 2 – 3 m.

What is SARS? How is it different from the flu?

The term “acute respiratory disease” (ARI) or “acute respiratory viral infection” (ARVI) covers a large number of diseases that are largely similar to each other. Their main similarity lies in the way of transmission (they enter the body along with inhaled air through the mouth and nasopharynx) and in a set of symptoms:

  • The patient has a fever, sore throat, cough, chills, muscle pain and headache for several days.
  • The most common symptom of respiratory disease is a runny nose; it is caused by a number of related viruses known as rhinoviruses.

With recovery, all these symptoms disappear and do not leave behind any traces.

In general, the causative agents of acute respiratory infections are transmitted from person to person through coughing or sneezing of the patient. Any person in close (approximately 1 meter) contact with another person with symptoms of SARS is at risk of exposure to potentially infectious inhaled droplets. Viruses can enter the body (in the eyes, nose or mouth) through the hands when in contact with an infected surface.

Personal hygiene can help prevent the spread of pathogens that cause respiratory infections.

Signs and symptoms of the flu Signs and symptoms of SARS
  1. Influenza comes unexpectedly and completely takes over your body in a matter of hours;
  2. Influenza is characterized by a sharp increase in temperature (in some cases up to 40.5 degrees), increased sensitivity to light, aches throughout the body, as well as pain: headache and muscle;
  3. On the first day of influenza, there is no runny nose, which is characteristic only of this virus;
  4. The most active phase of influenza falls on the third-fifth day of the disease, and the final recovery occurs on the 8-10th day.
  5. Given that the influenza infection affects the blood vessels, it is for this reason that hemorrhages are possible: gingival and nasal.
  1. The onset of the disease is gradual and most often begins with fatigue and an external manifestation of the virus, such as a runny nose;
  2. The next day after the activation of the disease, a dryish cough appears, which eventually transforms into a wet (expectorating).

Differences between COVID-19, colds and flu

As you know, the new coronavirus infection COVID-19 is transmitted mainly by airborne droplets. She is characterized by the presence of clinical symptoms of SARS (you can find a detailed educational program from Sevdzdrav at the link – https://sevdz.ru/mednavigator/profilaktika/koronavirus/).

Important! COVID-19 is sometimes asymptomatic, but this does not make the carrier of the virus any less contagious. Especially in such cases, people with chronic diseases suffer.

Key recommendations for the prevention of influenza and SARS for the population

It is especially important to observe preventive measures now – during the pandemic of a new coronavirus infection.

The self-isolation regime has been canceled, but the pandemic has not disappeared anywhere! We all need to think about our health and the health of those around us.

  • Avoid close contact with people who appear unwell, show fever (temperature) and cough.
  • Avoid crowded places or reduce time spent in crowded places.
  • Avoid touching your mouth and nose.
  • Observe hand hygiene – wash hands frequently with soap and water or use an alcohol-based hand sanitizer, especially when touching the mouth, nose.
  • Increase the flow of fresh air into living quarters, open windows as often as possible.
  • Wear a mask when in contact with a sick person.
  • Maintain a healthy lifestyle, including adequate sleep, eating “healthy” foods, and being physically active.

Preventive immunization of the population (vaccination) is the best prevention of influenza. In turn, the main danger of refusing to vaccinate is the possibility of getting the flu when in contact with a sick person. In addition, a person who has not been vaccinated is potentially dangerous to others, as he is a likely carrier of an infectious disease.

In detail: why vaccination is needed and where to get a flu shot in Sevastopol.

Recommendations for people with symptoms of SARS

  • If you feel unwell, stay at home and follow the recommendations of the doctor, if possible, keep a distance (1 meter) from healthy people.
  • Rest and drink plenty of fluids.
  • Cover your mouth and nose when coughing or sneezing with a handkerchief or other suitable material. Dispose of this material immediately after use or wash it. Wash your hands immediately after contact with secretions from the respiratory tract!
  • Wear a mask if you are in the common area of ​​the house near other people.
  • Tell your family and friends about the illness.

  • Carefully put on the mask so that it covers the mouth and nose, and tie it tightly so that there are as few gaps between the face and the mask as possible.
  • Avoid touching the mask when using it.
  • After touching a used mask, for example when removing it, wash your hands with soap and water or an alcohol-based hand sanitizer.
  • Replace the used mask with a new, clean, dry mask as soon as the used mask becomes damp (wet).
  • Masks intended for single use should not be reused.
  • Throw away disposable masks after each use and dispose of them immediately after removal.

Home care advice
