Overview
A fever is a temporary rise in body temperature, which is typically a response from the body's immune system. It is usually caused by an infection. For most people, a fever is generally not a cause for concern and usually goes away within a few days. Fever signs and symptoms can include sweating, chills, headache, and in infants, even a low fever may indicate a serious infection. The average body temperature is traditionally defined as 98.6 F (37 C), and a temperature of 100 F (37.8 C) or higher is generally considered to be a fever. Fever treatments include over-the-counter medications, but it is not always necessary to treat a fever if it is not causing discomfort. It is important to seek medical attention for fevers accompanied by severe headache, rash, unusual sensitivity to light, stiff neck, mental confusion, persistent vomiting, difficulty breathing, abdominal pain, or other symptoms causing significant discomfort.
Understanding the disease
Symptoms
The symptoms of a fever include a temporary rise in body temperature, which is usually caused by an infection. Other symptoms may include sweating, chills, headache, and body aches. If the fever is accompanied by severe headache, rash, unusual sensitivity to bright light, stiff neck and pain when you bend your head forward, mental confusion, strange behavior or altered speech, persistent vomiting, difficulty breathing or chest pain, abdominal pain, or a rash that comes and goes with the fever, it may be necessary to seek medical attention.
Development
The various fevers develop as a result of the body's immune response to an infection. When the immune system detects an infection, it triggers a series of reactions, including an increase in body temperature. The specific cause of a fever depends on the type of infection, such as viral, bacterial, fungal, or parasitic. Fever is a common symptom of many infectious diseases, including the common cold, influenza, and some more severe illnesses like viral hemorrhagic fevers, such as Dengue, Ebola, Lassa, Marburg, and Yellow fever. Fever is usually accompanied by other symptoms, such as chills, sweating, headache, body aches, and fatigue, depending on the underlying infection.
Assessment and Diagnosis
Triage
You should see a doctor if fever is suspected when there are accompanying severe symptoms such as severe headache, rash, unusual sensitivity to bright light, stiff neck and pain when you bend your head forward, mental confusion, strange behavior or altered speech, persistent vomiting, difficulty breathing or chest pain, or abdominal pain. Additionally, if the fever lasts longer than three days or is accompanied by a seizure, call 911 or seek immediate medical attention. It's important to consult your child's health care provider for guidance on special circumstances, such as a child with immune system problems or a preexisting illness. For adults, seek medical attention if the fever is 103 F (39.4 C) or higher or if any of the above-listed severe symptoms accompany the fever.
Diagnosis
To diagnose a fever, a healthcare provider may:
- Ask questions about your symptoms and medical history
- Perform a physical exam
- Take nasal or throat samples to test for respiratory infections
- Order tests, such as blood tests or a chest X-ray, as needed, based on your medical history and physical exam In the case of a fever of unknown origin, you may need to see specialists in one or more medical fields for further evaluations and tests.

Management and Treatment
Home Remedies
Here are some home remedies suggested for fever:
- Stay hydrated: Encourage the consumption of fluids, such as water, clear broths, frozen water or ice pops, and clear juices, to help prevent dehydration.
- Rest: Provide plenty of opportunities for rest and sleep, as these promote healing and recovery.
- Use over-the-counter medications: Acetaminophen (such as Tylenol) or ibuprofen (such as Advil or Motrin) can help reduce fever and relieve discomfort. Always follow the recommended dosage and age guidelines.
- Cold compress: Apply a cold compress, such as a damp cloth or ice pack wrapped in a towel, to the forehead or the back of the neck to help reduce fever. Be cautious not to apply ice directly to the skin.
- Dress lightly: Dress in lightweight, comfortable clothing and use lightweight bedding to help maintain a comfortable temperature.
- Humidifier: Use a cool mist humidifier to add moisture to the air, which may help relieve congestion and make breathing easier. It's important to note that while these remedies can help ease fever symptoms, they do not treat the underlying infection causing the fever. If the fever persists or is accompanied by severe symptoms, such as difficulty breathing, extreme drowsiness, or signs of severe illness, seek medical attention.
Treatment
Treatment for fever usually involves managing the symptoms to make the individual more comfortable. For most cases, fever will go away on its own within a few days. Over-the-counter medications, such as acetaminophen (paracetamol) or ibuprofen, can help reduce fever and relieve discomfort. Always follow the instructions on the package or consult with a healthcare provider for appropriate dosage. It's important to note that if the fever is accompanied by other severe symptoms, such as a stiff neck, severe headache, difficulty breathing, chest pain, abdominal pain, persistent vomiting, or mental confusion, you should seek medical attention immediately. Additionally, if the fever lasts for more than three days or is accompanied by a seizure, seek professional help. It's crucial to consult with a healthcare provider for guidance on treating fever in special circumstances, such as for children with immune system problems or preexisting illnesses.
Preparing for medical consultation
When preparing for an appointment regarding a fever, it is essential to be aware of any pre-appointment restrictions and ask if there's anything you need to do in advance. You should also write down information about the fever, such as when it started, how and where it was measured, and any other symptoms. Note if you or your child has been around anyone who's been ill. Additionally, make a list of all medications, vitamins, and supplements you or your child are taking, and write down questions to ask the care provider. Some basic questions to ask include:
- What's likely causing the fever?
- What kinds of tests are needed?
- What treatment approach do you recommend?
- Is medicine necessary to lower the fever?
- Are there any restrictions that I need to follow? During the appointment, be prepared to answer questions about the fever's onset, the method used to take the temperature, the environment's temperature, any fever-lowering medication taken, other symptoms, chronic health conditions, medications, exposure to ill individuals, recent surgeries, recent travel outside the country, and what, if anything, seems to improve the symptoms.
