Flu, also called influenza, is a contagious respiratory illness caused by flu viruses that infect the sinuses (nose and throat) and sometimes the lungs. Influenza A and B are the two main types that cause the annual influenza outbreak. In general, the flu is worse than the common cold, and symptoms are typically more intense and begin more abruptly. Colds are usually milder than the flu.
How do I get the flu?
Flu viruses are spread mainly by tiny droplets made when people who already have the flu cough, sneeze, or talk. These droplets can land in the mouths or noses of people who are nearby.
Who can get the flu?
Flu virus infection is very common, so anyone can catch the flu. You can pick up the flu from being around others who have the flu or by coming into contact with the flu virus. You can help prevent the flu by washing your hands often, staying away from individuals who are sick, drinking plenty of water, and getting rest.
What does the flu feel like? Symptoms of the flu:
- fever or feeling feverish
- chills
- cough
- sore throat
- runny or stuffy nose
- muscle or body aches
- headaches
- fatigue (tiredness)

Flu Symptoms 2023
The flu consists of two main strains: Influenza A and Influenza B. Influenza A typically appears early in the year and accounts for more than two-thirds of all flu cases. Influenza B tends to show up later in the season—around February or March. Influenza A has been thought to be more deadly; however, both strains can cause severe sickness and hospitalization. In recent years, influenza B has been more severe in children. Another main difference is that influenza A can be spread among humans and animals, while influenza B is only spread among humans.
Flu symptoms in 2023 have stayed consistent with those of prior years, although reports of stomach flu have been reported.
