A viral fever is any fever that happens as a result of a viral infection. Viruses are tiny germs that spread easily from person to person.
When you contract a viral condition, such as a cold or flu, your immune system responds by going into overdrive. Part of this response often involves raising your body’s temperature to make it less hospitable to the virus and other germs. Most people’s usual body temperature is around 98.6°F (37°C). Anything 1 degree or more above this is considered a fever.
Unlike bacterial infections, viral illnesses don’t respond to antibiotics. Instead, most simply have to run their course. This can take anywhere from a couple of days to a week or longer, depending on the type of infection. While the virus runs its course, there are several things you can do to help manage your symptoms. Try to drink as much as you can when you have a viral fever to replenish lost fluids.
