Did you know you could catch the flu from someone even if they’re fever-free? Here’s AFC’s guide to identifying the flu without a fever.
When flu season arrives in Caldwell County, many people assume they’re in the clear as long as they don’t have a fever, or aren’t around anyone who does. So, they continue to take their children to play at the MLK Jr. Center or spend an evening with them at Main Street Magic Cafe.
But while a fever is one of the most recognizable flu symptoms, it isn’t always present. That leads to a common and important question: Can you catch the flu from someone who doesn’t have a fever?
The answer is yes. The flu can still spread even when a fever isn’t part of the picture. Understanding how the flu works, how it spreads, and when to seek care can help keep you and your community healthier throughout flu season.
What Is the Flu?
The flu, also known as influenza, is a contagious respiratory illness caused by a virus. It primarily affects the nose, throat, and lungs and spreads easily from person to person. While most people recover within a week or two, the flu can cause uncomfortable symptoms and sometimes lead to complications, especially for children, older adults, and individuals with weakened immune systems.
It’s also important not to confuse the flu with the “stomach flu.” Influenza does not typically cause vomiting or diarrhea. Instead, it affects the respiratory system and is known for causing sudden, intense symptoms.
Because the flu is highly contagious, even mild or early symptoms can still put others at risk.
Flu Symptoms to Watch Out For (Other Than a Fever)
When a fever is absent, it can be harder to tell whether symptoms are caused by the flu or a common cold. Flu symptoms can range from mild to severe and may include:
- Cough
- Sore throat
- Runny or stuffy nose
- Muscle or body aches
- Headaches
- Fatigue
- Chills
- Loss of appetite
One helpful way to tell the difference between a cold and the flu is how symptoms appear. Cold symptoms usually develop gradually. Flu symptoms, on the other hand, may take a few days to show up but tend to appear suddenly and feel much more intense once they do. That sudden onset is often a strong indicator of the flu.
How the Flu Spreads
The flu spreads through respiratory droplets released when an infected person coughs, sneezes, or talks. These droplets can land in the mouths or noses of nearby people or contaminate surfaces that others touch.
The virus enters the body through the eyes, nose, or mouth. Since flu symptoms don’t appear immediately, people can spread the virus before they realize they’re sick.
Generally, individuals are most contagious during the first three to four days after symptoms begin. However, it’s possible to spread the flu up to one day before symptoms appear and remain contagious for about a week afterward. Children and people with weakened immune systems may spread the virus for even longer.
So yes, you can absolutely catch the flu from someone who doesn’t have a fever. A fever simply signals that the body is fighting an infection; it doesn’t determine whether someone is contagious.
