A fever is an elevated body temperature, generally defined as 100.4°F (38°C) or higher. It is a common symptom associated with COVID-19, a viral illness.
How Long a COVID Fever Typically Lasts
A fever associated with COVID-19 usually lasts for a few days, often returning to normal within three to four days. However, duration can vary, with some fevers lasting anywhere from two to ten days. Not everyone infected will develop a fever; some may experience only a low-grade temperature or none at all. Even when present, fever can sometimes come and go.
Why Fever Duration Varies
The length of a COVID-19 fever can vary significantly among individuals due to several factors. Vaccination status plays a role, as vaccinated individuals may experience milder symptoms, including shorter fever durations or no fever at all. The specific virus variant can also influence how long a fever lasts, potentially leading to different symptom profiles.
Individual immune responses are another factor, as each person’s body reacts uniquely to the infection. Age can also affect fever duration, with adults sometimes more prone to fever than children, though children commonly develop fever. Underlying health conditions can also contribute to variations in fever duration and symptom severity.
When to Contact a Healthcare Provider for Fever
Knowing when to seek medical attention for a COVID-19 fever is important. You should contact a healthcare provider if your fever persists beyond a few days or if your symptoms begin to worsen. Immediate medical attention is necessary if you experience emergency warning signs, such as trouble breathing or difficulty catching your breath.
Other serious symptoms that warrant prompt medical care include persistent pain or pressure in the chest. New confusion or an inability to wake or stay awake are also urgent signs. Observe for pale, gray, or blue-colored skin, lips, or nail beds, as these can indicate dangerously low oxygen levels. If a very high fever (over 103°F or 40°C) does not improve after a few days of home treatment, or if you become unusually drowsy or confused, seek medical advice.
Managing COVID Fever at Home
For managing a COVID-19 fever at home, several strategies can help alleviate symptoms. Rest is important, as the body needs energy to fight the virus. Staying well-hydrated by drinking plenty of fluids, such as water or clear broths, is also beneficial, especially since fevers can lead to fluid loss through sweating.
Over-the-counter fever reducers, like acetaminophen or ibuprofen, can effectively lower a fever and ease associated body aches. Follow the recommended dosages on the labels for these medications. Wearing comfortable clothing and maintaining a comfortable room temperature can also contribute to feeling better while the fever runs its course.
