Influenza (Flu)

Influenza (flu) spreads easily by coughing and sneezing. Flu can cause a high fever (usually over 101˚ F), cough, headache, and muscle aches. This respiratory virus can lead to pneumonia and heart problems. Flu can be very serious for babies and they often need to be hospitalized if they get flu. Flu is even more serious for kids with chronic illnesses, such as asthma, heart disease, or diabetes.

Symptoms include:

  • Fever.
  • Headache.
  • Tiredness.
  • Dry cough.
  • Sore throat.
  • Nasal congestion.
  • Muscle aches.

If you or someone you know has these symptoms and they are severe, contact your health care provider as soon as possible.

Flu vaccine can protect against certain types of the influenza virus. Each year a new vaccine is produced based on the types of influenza virus circulating that year. Flu vaccine is recommended for persons aged 50 years or older, kids aged 6 months to 18 years, and anyone with a chronic illness or special medical needs. The vaccine is also available for anyone who wants to avoid getting the flu.

The vaccine is not perfect for preventing all flu symptoms for elderly and frail people; however, it is excellent in preventing severe influenza, hospitalization, and death. If you get the flu after being vaccinated, it will be a much milder case.
