Communicable Diseases


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.

Actions To Help Prevent the Flu

  • GET VACCINATED: A yearly flu vaccine is the first and most important step in protecting against flu viruses 
  • STOP GERMS: Take everyday actions to help stop the spread of germs. Cover coughs and sneezes, stay home when you’re sick, and wash your hand frequently 
  • GET TREATMENT: If you become sick and are at increased risk for serious complications from flu, contact your doctor right away to discuss the benefits of antiviral medications that can be used to treat flu illness.
