Temperature check: how long does a fever last?

Fevers are like the body's red alert system, signaling something isn't quite right. They can make you feel hot and uncomfortable and often come accompanied by a whole host of symptoms. But one burning question that lingers in many minds is, "How long does a fever last?"

So, whether you're navigating a feverish episode right now or simply seeking knowledge to prepare for the future, join us as we take a temperature check.

What is considered a fever? Fever defined.

A fever is your body's way of alerting you to an underlying issue. But what exactly constitutes a fever in terms of body temperature? Knowing the threshold to recognize when your body is running hotter than usual is essential.

Generally, a fever is considered when your body temperature rises above 100.4°F when measured orally. Rectal measurements tend to be slightly higher, with 100.6°F or higher typically indicating a fever.


Core body temperature.

When measured orally, the average normal body temperature is around 98.6°F. However, body temperature can naturally fluctuate throughout the day, often slightly lower in the morning and higher in the late afternoon and evening.


Mild vs. high fevers.

Fevers can vary in severity. A mild fever might range from 100.4°F to 102.2°F, while a high fever is typically above 102.2°F.


Why it matters.

Recognizing a fever is crucial because it often signals that your body is fighting off an infection or other health issue. It's a part of your body's immune response.

Understanding the temperature threshold for fever is the first step in recognizing when your body is running a bit too hot.


How long does a fever last with COVID?

COVID-19, caused by the novel coronavirus SARS-CoV-2, has brought new attention to fevers as one of its hallmark symptoms. Understanding how long a fever typically lasts with COVID-19 can help individuals monitor their health and make informed decisions.

Initial fever.

For many COVID-19 patients, the fever often begins as an early symptom. It can last for several days, typically ranging from 2 to 14 days after exposure to the virus.

COVID-19 fever duration.

The duration of the fever with COVID-19 can vary widely from person to person. Some individuals experience a fever for a few days, while others may have a prolonged fever that lasts up to a week or more.

Fever as a symptom of COVID-19.

It's important to note that a fever may not be the only symptom of COVID-19. Many individuals also experience cough, shortness of breath, fatigue, loss of taste or smell, and muscle aches.

Monitoring and isolation.

If you suspect or have been diagnosed with COVID-19, closely monitoring your symptoms, including fever, is crucial. Isolation protocols are typically recommended to prevent the potential spread of the virus to others.

Seeking medical care.

If you experience severe symptoms with fever, such as chest pain, confusion, and bluish lips, seek immediate attention in the emergency room. Less severe symptoms such as symptoms of a common cold can be easily and effectively evaluated and treated at CityMD.
