Does the Flu Always Cause a Fever?

December 22, 2023

Flu is caused by the influenza virus. Common symptoms include fever, cough, fatigue, a runny nose, chills, a sore throat and loss of appetite. However, not all people develop a fever as a result of an influenza infection. Children usually develop a high fever close to 1000F, but not all adults do. In this blog, we’ll explore the relationship between the flu and a fever. Visit AFC Urgent Care Cortez for same-day treatment!

The Influenza Virus

The flu is caused by the influenza virus. The disease is spread through inhaling droplets from the coughs and sneezes of people who have the flu. A runny nose, a dry cough, tiredness, muscle and joint pain are commonly observed symptoms. There may also be diarrhea, vomiting and stomach pain, coupled with a loss of appetite. A cold can appear more gradually and mainly affects your nose. You can carry on normally with a cold, while the flu will leave you feeling more debilitated.

Is the Flu Always Accompanied by a Fever?

Although it is one of the first symptoms of the flu virus, influenza is not always accompanied by a fever. This is especially when people have already taken some antibiotics as a way of protecting themselves from the effects of the virus. Fever is the body’s way of protecting itself from infection, and should not always be viewed as bad. A flu related cough can last for about two weeks. If your immunity is strong, you could recover from the effects of the flu within a week or two. You may feel lethargic or run down during this period.

Can the Fever be Caused by Other Conditions?

It is possible that fever experienced during an attack of the flu virus is not really caused by influenza. It may in fact be caused by other diseases, like almost any other infection. This makes it important to seek a professional diagnosis. A rise in body temperature may also be brought on by certain medications or taking a vaccine.

How to Recover from Influenza

If you are otherwise healthy, you can take some over the counter medicines to relieve flu symptoms. Be careful to practice good hygiene and wash your hands regularly with soap and warm water. Drink plenty of fluids and herbal teas. Eat easily digestible foods and avoid dairy products. Use tissues to wipe hands and nose and all the surfaces you touch, even your computer keyboard and mouse.
