Flu Season

Influenza, better known as the flu, is a contagious respiratory illness caused by influenza viruses that infect the nose, throat and sometimes the lungs. Influenza viruses spread primarily through tiny droplets made when people with the flu cough, sneeze or talk.

Most people who get the flu recover without any issues. However, the flu can be associated with very serious illness and lead to hospitalization or death. The risk is especially high for seniors, young children, pregnant people, and people with chronic medical conditions. It commonly causes people to miss school and work.

Flu season typically runs from October through May, with the peak coming in February. Approximately, 3-11 percent of the U.S. population catches influenza every year — which equates to about 100,000 Allegheny County residents, annually.

While the severity of the 2022-2023 flu season cannot be predicted, it may be severe. The past two flu seasons were unusually mild because of behaviors related to the COVID-19 pandemic (masking, social distancing, working from home, and at-home school). Now, many of those behaviors have changed.

The best way to reduce your risk from influenza illnesses, hospitalizations and death is to get vaccinated every year. The influenza vaccination, or flu shot, has been used for almost 80 years. Everyone 6 months and older should get a shot every flu season, with rare exception. For people 65 years and older, particular flu shots help provide even better protection. Getting the shot protects you, your family, and your community. Since the vaccine is most effective in the first six months following the shot, the best time to get it is before the end of October. Cases can occur as late as May, so even people who don’t get it in October should still get it later in the season. 

Finally, to protect yourself and others from getting the flu, cover your mouth when coughing or sneezing, wash your hands regularly, consider wearing a mask in crowded places, and stay home if you are sick. Maintain your overall health by eating a healthy diet, getting proper rest, being physically active, and reducing stress.
