Influenza (flu) is a contagious respiratory illness caused by influenza viruses that infect the nose, throat, and lungs. Some people, such as older people, young children, and people with certain health conditions, are at higher risk of serious flu complications. There are two main types of influenza (flu) viruses: Types A and B. The influenza A and B viruses that routinely spread in people (human influenza viruses) are responsible for seasonal flu epidemics each year.
The first and most important step in preventing flu is to get a flu vaccine each year. The flu vaccine has been shown to reduce flu-related illnesses and the risk of serious flu complications that can result in hospitalization or even death. CDC also recommends everyday preventive actions (like staying away from people who are sick, covering coughs and sneezes and frequent hand-washing) to help slow the spread of germs that cause respiratory (nose, throat, and lungs) illnesses, like flu.
The CDC recommends that everyone 6 months and older should receive a yearly flu vaccine. Flu can cause mild to severe illness. Not only will the flu vaccine help decrease the number of flu cases alongside COVID-19 cases within the community.
