(Indianapolis, Ind.) - The number of flu-related deaths in Indiana continues to climb.

The Indiana State Department of Health announced Monday that 21 people have now died from illness related to the flu. There were 15 deaths reported as of Wednesday, January 9.

Two of the Indiana deaths were under the age of 18, one was between ages 50 and 64, and the others were people 65 and older. Nationally, 20 children age 17 or younger have died this flu season, according to the Centers for Disease Control and Prevention.

Although the nation is well into the flu season, doctors are still urging people to receive the vaccine if they haven’t already. No official shortages of the influenza vaccine have been reported in Indiana, state health officials say. Flu vaccine can typically be found at local health departments, pharmacies and health care providers.

Places where citizens can find the flu vaccine are listed at www.flu.gov.

Aside from the vaccine, there are other steps people can take to help limit the spread of influenza. Remember the three C’s:

Clean. Properly wash your hands frequently with warm, soapy water.

Cover. Cover your cough and sneeze with your arm or a disposable tissue.

Contain. Stay home from school/work when you are sick to keep your germs from spreading.
