COVID recovery with fever
Informed by recognized medical guidance
Overview
COVID is a viral infection that can cause a fever. A fever is when your body temperature goes up. It is a sign that your immune system is working to fight off the virus. Recovering from COVID with a fever means taking care of yourself while this symptom lasts and allowing your body to heal.
Key facts
- A fever is common during COVID and usually improves within a few days.
- A fever is a normal response that helps your body fight the infection.
- Rest, fluids, and simple comfort measures can help you recover.
- Seek medical help if you have trouble breathing or a fever lasts too long.
Yes. Fever is one of the most common symptoms of COVID. Many people have a fever for the first few days of illness, and then it gradually goes away as they recover.

- Sometimes a secondary bacterial infection can cause a new or prolonged fever
Risk factors

When to see a doctor
See a doctor urgently if:
- A temperature above 40°C (104°F) that does not go down with self-care
- Breathing problems or chest pain at any time
- Feeling confused, very sleepy, or unable to wake up
- A seizure
- Being unable to keep any fluids down
Book a routine appointment if:
- Fever that lasts beyond a few days
- Fever that improves and then worsens
- Questions about managing symptoms at home
- You have a health condition that puts you at higher risk
Diagnosis
A healthcare provider will ask about your symptoms and measure your temperature. If needed, they can offer a COVID test to confirm the infection. Most people can manage a COVID fever at home without a formal diagnosis, but testing can guide treatment and help you protect others.
Tests that may be done
- Body temperature reading with a thermometer
- COVID test using a swab from the nose or throat
- In some cases, blood tests if you are in hospital or have complications
What to expect at your appointment
Your provider will check your temperature, heart rate, and breathing. They will ask how long the fever lasted and whether you have other symptoms. They will give advice about fluids, rest, and when to seek urgent care. For most people, no special tests are needed for a simple fever.
Treatment
Fever is a symptom, not an illness. The goal is to keep you comfortable while your immune system works. You do not need to bring a mild fever to normal. Treatment focuses on rest, fluids, and safe fever-reducing options if you feel very uncomfortable.
Self-care at home
- Drink plenty of water, clear soup, or oral rehydration fluids in small amounts throughout the day
- Rest as much as possible and avoid heavy activity
- Dress lightly and keep the room at a comfortable temperature
- Use a damp cloth on your forehead or arms if it helps you feel cooler
- Avoid alcohol and limit caffeine
- Monitor your temperature and symptoms regularly
Medical treatments
In most cases, a COVID fever is managed at home with rest, fluids, and simple over-the-counter fever reducers. For people at higher risk, a healthcare provider may consider antiviral treatment for COVID, but this depends on your health and how quickly you start treatment. Always discuss options with your care team and never take more than the recommended amount of any medicine.
When is surgery considered?
Surgery is not needed for a fever caused by COVID. In rare cases, if a complication like a bacterial infection or severe lung problem develops, a hospital stay or procedure may be necessary, but this is uncommon.
Living with this condition
Fever can make you feel tired and achy. Plan to rest for a few days. Listen to your body and do not rush back to your usual routine. It is normal to have less energy for a while. Gradually increase your activities as you feel stronger.
Lifestyle tips
- Get plenty of sleep and rest
- Keep drinking fluids regularly, even if you do not feel thirsty
- Do very light activity like sitting up or taking a short walk only when you feel able
- Wash your hands often to avoid spreading the virus
- Stay away from others while you still have a fever
Diet and exercise
Eat light meals if you feel hungry. If you do not feel hungry, choose soups, broths, or yogurt. You do not need to force yourself to eat, but keeping fluid intake up is important. Wait until your fever has gone and your energy returns before resuming exercise, and then start slowly.
Mental health and emotional wellbeing
Being unwell with a fever can feel lonely or worrying. You may feel low in energy and mood. This is a normal response. If you feel very anxious or overwhelmed, talk to your doctor or a trusted friend. It is also normal to feel frustrated if recovery takes longer than expected.
Prevention
You can reduce your chances of getting COVID by practising good hygiene, staying up to date with vaccines, and avoiding close contact with people who are infected. If you are already sick, staying at home and covering coughs helps protect others.
Vaccines
COVID vaccines are safe and effective. They lower your chance of getting infected and reduce the risk of severe symptoms like high fever, especially if you are up to date with recommended boosters.
Screening programmes
Routine testing is not always needed, but if you have a fever and may have been exposed to COVID, testing can help you know whether to self-isolate and protect others.
Complications
If left untreated
- Dehydration from not drinking enough fluids
- Extreme tiredness or weakness that lasts longer than usual
- Pneumonia or lung infection in severe COVID cases
- A secondary bacterial infection that may need medical treatment
Long-term outlook
Most people with a COVID fever recover fully within a week or two. The fever usually goes away as the body fights off the virus and the infection settles. Some people may feel tired for a while longer, but that is normal. With rest, fluids, and good care, the vast majority of people make a complete recovery.
