There’s an estimated 375-thousand Floridians living with some form of hepatitis… and many don’t know they are infected.

The Florida Department of Health is raising awareness of the different types of hepatitis spreading through the state. Hepatitis C is the most deadly and is spread through the exchange of bodily fluid.

Louis Pierno, lost his brother to hepatitis. He was a firefighter and contracted the virus helping a victim.

“Get tested. Be aware of your body. Firemen get tested a lot as they should. You know it’s something you can’t see. Being aware of this disease is very important, for every one not just firefighters.”

Seven firefighters in Florida have died from hepatitis. Today marks World Hepatitis Day.
