When to Go to the ER with a Fever

What Is a Fever?

The term “fever” gets tossed around a lot, but the details of what a fever does for your body are not often discussed. A fever is usually a symptom of an underlying condition or infection. The part of your brain called the hypothalamus is responsible for controlling body temperature, and the normal body temperature lies at around 98.6°F or 37°C.

A fever occurs when your body is trying to kill a virus or bacteria that causes an infection. This is because a higher temperature makes the body a less welcoming host for replicating viruses and bacteria. A mild fever is a good indication that your immune system is doing its job, but fevers are not always brought on by infections. Other potential causes of fever include amphetamine abuse, alcohol withdrawal and environmental fevers like heat stroke.

When Should You Go to the ER for a Fever?

While it’s true that a fever typically means your immune system is hard at work, the fever can sometimes raise to unhealthy levels. When the body temperature exceeds 105°F, it exposes the proteins and body fats to temperature stressors that can interfere with their functioning. Prolonged exposure can lead to cellular stress, infarctions, necrosis, seizures and delirium.

To prevent these conditions from occurring, here are some signs that a fever warrants a trip to the ER.

For an Infant Younger than 90 Days Old

If changes in appetite are occurring along with the fever, you should seek emergency care.
If changes in behavior or sleeping patterns accompany the fever, you should seek emergency care.
If diarrhea or vomiting are occurring along with the fever, you should seek emergency care.
If your infant is constipated and has a fever, you should seek emergency care.
If your infant has a cold and a fever, you should seek emergency care.
If your infant has a rash or skin discoloration and a fever, you should seek emergency care.
If your infant has eye discharge, you should seek emergency care.
If your infant is having difficulty waking up to feed alongside a fever, you should seek emergency care.
If your infant is having difficulty breathing, you should seek emergency care.

For a Baby Between the Ages of 90 Days and 36 Months Old

If your baby is experiencing any of the symptoms above alongside a fever, you should seek emergency care.
If your baby is not immunized and has a fever, you should seek emergency care.

For a Child Older than 36 Months Old

If your child is experiencing any of the symptoms above alongside a fever, you should seek emergency care.
If your child is experiencing abdominal pain and has a fever, you should seek emergency care.
If your child is communicating feelings of persistent discomfort alongside a fever, you should seek emergency care.

For an Adult

If an adult is experiencing a painful headache and has a fever, they should seek emergency care.
If an adult is experiencing abdominal pain and has a fever, they should seek emergency care.
If an adult is having difficulty breathing or chest pain accompanied by a fever, they should seek emergency care.
If an adult has a compromised immune system and comes down with a fever, they should seek emergency care.
If an adult has had chemotherapy recently and has a fever, they should seek emergency care.
If the adult’s fever lasts for more than three days, they should seek emergency care.
If the adult’s fever rises above 103°F, they should seek emergency care.
If the adult’s fever is accompanied by nausea, confusion or a rash, they should seek emergency care as these symptoms may be caused by meningitis.
If the adult’s fever is accompanied by confusion, a rapid heartbeat or dizziness, they should seek emergency care as these may be signs of a heat stroke.

Please note that these lists are not all-inclusive. If you are doubtful that the fever will resolve on its own, it is best to have the condition examined by a medical professional.

How To Know If You Should Go To The ER For A Fever

If you are otherwise healthy and alert, having a low-grade fever may not necessarily be cause for concern. However, an elevated temperature can be indicative of another process or illness that needs to be treated. A severe or prolonged fever can even cause complications on its own. Because there are a number of possible causes of fever, many of which trigger a similar set of symptoms, it can be challenging to self-diagnose your condition. The expert team of board-certified physicians at both of iCare ER & Urgent Care’s convenient locations in Frisco and Fort Worth, TX provides prompt and reliable evaluation, diagnosis, and treatment for patients presenting with fever. Find out more about the possible causes of fever here, and learn what situations may warrant a visit to the ER for fever.

What is a fever?

For most adults, a normal body temperature is between 97°F and 99°F, though 98.6°F is generally accepted as the standard of normal. When a patient’s body temperature becomes elevated to 100.4°F or higher, he or she is considered to have a fever. Oftentimes, a fever indicates that the body is fighting off a virus, infection, or another pathogen. Common symptoms of a fever include:

Sweating
Chills
Headache
Body aches
Fatigue
Loss of appetite

What causes a fever?

There are a variety of potential reasons why a person’s body temperature may become elevated, either temporarily or for several days or weeks. Some of the most common causes of a fever include:

Virus
Infection
Cold and/or flu
Stomach bug
Recent vaccination
Heat exhaustion

How long does a fever last?

Depending on the cause of the fever, the patient’s overall health, what treatments are given, and other factors, a fever can last anywhere from several hours to several weeks. For some of the most common illnesses, such as the flu, most people demonstrate an elevated temperature for about 2 – 4 days.

How high is too high for a fever?

Fever of 103°F or above is considered high grade and should be treated immediately. However, even a low-grade fever may be a sign of a dangerous problem for infants and babies. If you are concerned about fever in your infant, your child, or yourself, visit your nearest Fort Worth or Frisco emergency room within iCare ER & Urgent Care’s unique dual-hybrid facility.

When should you go to the ER for a fever?

For patients who are otherwise healthy, alert, and have an obvious explanation for their low-grade fever – such as a cold – at-home remedies and monitoring may be sufficient. However, any fever above 103°F should be treated immediately in the ER. In addition, if you or your child are experiencing any of the following symptoms in conjunction with a fever, a trip to the ER is warranted:

Confusion
Severe pain (abdominal pain, headache, muscle pain, etc.)
Sensitivity to light
Skin rash or irritation
Protracted nausea or vomiting
Inability to eat or drink
Difficulty breathing
Chest pain
Seizure
Inability to stay awake
Fever of 103°F or higher
Fever lasting longer than 3 – 4 days (children)
Any fever (infants)

How is a fever treated in the ER?

To determine the cause of your fever, one of our board-certified ER physicians in Frisco or Fort Worth will perform a thorough examination, take a detailed health history, measure certain vital signs, and possibly draw laboratory studies. Depending on the severity of your condition, the cause of your fever, and other factors, your physician will recommend the most appropriate course of treatment, which may include antibiotics, other medications, fluids, and rest.

Get prompt treatment and rapid relief for your fever by visiting your nearest emergency room in Frisco or Fort Worth, TX

Lassa fever – Nigeria

Outbreak summary

Nigeria is currently experiencing a major outbreak of Lassa fever, during which during the period from the 1st to the 15th epidemiological week of 2023 (week ending 16 April) There were 4702 suspected cases, five probable cases and 877 confirmed cases. Among cases with a confirmed diagnosis, 152 deaths were registered (case fatality rate 17%). Lassa fever is endemic in Nigeria and parts of West Africa, where the African polynipple rat is a major reservoir of the Lassa virus.

The implementation of anti-epidemic measures in connection with the current outbreak is difficult because the country currently has to respond to a number of emergencies at the same time.

The disease is characterized by a wide variety of symptoms, and therefore the diagnosis can be difficult. Most infections (about 80%) caused by the Lassa virus are asymptomatic or mild. However, the infection can cause severe disease with multiple organ dysfunction, with or without bleeding. Therefore, laboratory testing is required to confirm the diagnosis.

Laboratory-confirmed cases of Lassa fever have been reported in states bordering Cameroon (Adamawa, Benue, Cross River and Taraba) and Benin (Oyo and Niger). The overall risk at the regional and global levels is assessed as low because the main route of transmission of Lassa virus is through contact with food or household items contaminated with rat excrement. There is a low level of human-to-human transmission.

Lassa fever epidemiological situation

Nigeria is experiencing a major outbreak of Lassa fever with 4702 suspected cases, five probable cases and 877 cases reported during the period 1st to 15th epidemiological week 2023 (week ending 16 April) with a confirmed diagnosis. Among cases with a confirmed diagnosis, 152 deaths were registered (case fatality rate 17%). The number of cases with a confirmed diagnosis increased by 20% compared to the same period in 2022 (733 cases).

Cases have been reported in 101 Local Government Areas (LGAs) in 26 of 36 states, including the Federal Capital Territory (FCT). Three states have a high concentration of confirmed cases (72%): Ondo (32%), Edo (29%) and Bauchi (11%). Laboratory-confirmed cases of Lassa fever have been reported in states bordering Cameroon (Adamawa, Benue, Cross River and Taraba) and Benin (Oyo and Niger).

Lassa fever epidemiology

Lassa fever is an acute viral hemorrhagic disease caused by the Lassa virus. The virus is most commonly transmitted to humans by direct contact with infected rodents of the genus Mastomys or by contact with food or household items contaminated with the urine or droppings of infected rodents. Accordingly, the virus is transmitted to a person through cuts and scratches or by inhalation of dust particles contained in the air. Person-to-person transmission can occur through direct contact with the blood or body fluids of an infected person, but is rare. Secondary transmission in health care settings can occur when the disease is detected late and treatment is started, and when adequate infection prevention and control (IPC) measures are not followed.

Most Lassa virus infections (about 80%) are asymptomatic or mild, but in about 20% of cases the virus can cause severe disease, sometimes with multi-organ dysfunction with or without bleeding. Without proper laboratory testing, the diagnosis of Lassa fever is difficult due to the variety of possible symptoms of the disease, from asymptomatic infection to multiple organ failure and death.

In patients hospitalized with severe disease, the case fatality rate is typically between 1% and 15%. The disease is particularly severe in the later stages of pregnancy, with rates of maternal death and/or fetal loss exceeding 80% during the last trimester. Maintenance therapy with rehydration and symptomatic treatment in the early stages of the disease is essential to increase the chances of survival. The antiviral drug ribavirin is used to treat Lassa fever, but its effectiveness has not been proven. To date, there is no vaccine against Lassa fever.

The disease was first reported in 1969 in Borno State, Nigeria, where it is endemic. Transmission of infection is observed throughout the year. However, large seasonal outbreaks occur during the dry season, usually from December to April.

In 2023, 42 cases were reported among healthcare workers in 11 states during the period from the 1st to the 15th epidemiological week. During epidemiological week 15, 2023 (April 10–16), 141 new cases with suspected Lassa fever, nine new confirmed cases, and one new confirmed case with a fatal outcome (case fatality rate of 11%) were reported.

The implementation of anti-epidemic measures in connection with the current outbreak is difficult because the country currently has to respond to a number of emergencies at the same time. These include outbreaks of COVID-19, diphtheria, meningitis, measles, cholera and ongoing humanitarian crises. In addition, the country is forced to solve security problems, which makes it difficult to carry out anti-epidemic measures in a timely manner.

Public health response

The Nigerian Centers for Disease Control and Prevention (NCDC) and health authorities in affected states are taking the lead in controlling the outbreak. On January 28, 2023, the National Center for Emergency Situations (ECS) of the NCDC became operational, and Rapid Response Teams (RRTs) were sent to the states of Bauchi, Benue, Ebonyi, Edo, Ondo and Taraba.

Anti-epidemic measures include:

surveillance: detection, monitoring of cases and outbreaks of the disease and laboratory testing;
care for the sick;
preventive measures: educating the public about personal hygiene, food safety and rodent control in the place of residence and work;
response: prescribing antiviral drugs, supportive care to confirmed patients, and tracking contracted individuals to identify those who may have been exposed to the virus.

To strengthen the response to the Lassa fever outbreak in Nigeria, the NCDC, in collaboration with WHO and other partners, developed a national outbreak prevention and control action plan. This plan includes measures to improve surveillance, increase the efficiency and capacity of national laboratories, increase public awareness and ensure greater access to treatment and care services for patients.

WHO risk assessment

Lassa fever is an acute hemorrhagic fever disease that is endemic in West Africa. Confirmed outbreaks and sporadic cases of Lassa fever have been reported in Benin, Burkina Faso, Côte d’Ivoire, Guinea, Ghana, Liberia, Mali, Sierra Leone, Togo and Nigeria. In some regions, rodents of the genus Mastomys are eaten.

Nigeria is a Lassa fever endemic country and has developed the capacity to control outbreaks of this disease, but the overall risk at the national level is currently assessed as high due to several factors:

increase in the number of confirmed cases compared to the same period in previous epidemic seasons;
reduced national capacity due to the need to respond to a range of current health emergencies, which has overburdened the country’s health system and limited the availability of medical resources;
lack of personal protective equipment (PPE), which poses a high risk of spread of healthcare-associated infections;
delays in transporting biomaterial specimens for laboratory testing in several states resulting in delayed confirmation of diagnosis and provision of treatment and care;
Poor health infrastructure, poor sanitation and continued presence of virus-carrying rodents;
insufficient information and education of the public and health care workers about Lassa fever, which can lead to further delays in diagnosis and treatment and increases the risk of infection and the likelihood of death.

Overall regional and global risk is assessed as low because Lassa virus is transmitted to humans primarily from animals and there is low human-to-human transmission.

WHO guidelines

Prevention of Lassa fever involves good hygiene at the community level to control the entry of rodents into homes. Effective measures include keeping grains and other foodstuffs in rodent-proof containers, removing waste disposal sites from homes, keeping homes clean, and keeping pet cats.

When caring for patients in health care settings, regardless of the suspected diagnosis, health care workers should always follow standard infection prevention and control measures. These measures include practicing hand and respiratory hygiene, using personal protective equipment against splashes or other contact with infectious materials, using safe injection practices, and ensuring the safe burial of the deceased.

Healthcare workers caring for patients with suspected or confirmed Lassa fever should take additional infection control measures to prevent contact with patients’ blood and body fluids, and with infected surfaces or materials, such as clothing and bedding. When in close contact with patients with Lassa fever (within one meter), healthcare workers need face protection (face shield or surgical mask and goggles), a clean, non-sterile long-sleeved gown, and gloves (sterile gloves are required for some medical procedures).

There are currently no registered vaccines to protect people against Lassa fever. In the early stages of the disease, the antiviral drug ribavirin may be an effective treatment for Lassa fever, but the evidence is conflicting. Evidence on the effectiveness of ribavirin as a post-exposure prophylactic for Lassa fever is not available.

WHO continues to recommend that all Lassa fever endemic countries improve their early case detection and treatment in order to reduce the number of deaths.

Based on available information, WHO does not recommend any restrictions on passenger or trade traffic for Nigeria.
