INDIANAPOLIS, Ind. (WOWO): Since October, 19 people have died of influenza associated illnesses, including two children.

Most of the deaths have occurred among those who are at higher risk of complications from the flu – the elderly, very small children, pregnant women and those with underlying medical conditions.

The Indiana State Department of Health says there’s been an increase in flu activity, including severe illnesses in schools, long-term care facilities and correctional facilities in recent weeks.

Distinguishing a cold from the flu can be tough sometimes. If you’re sneezing, have a sore throat and a stuffy or runny nose, it’s a cold. There can be mild body aches and fatigue with a cold, but if there’s a fever and you feel like you just can’t get out of bed, it’s more likely the flu.

Doctors recommend that everyone age 6 months and older get an annual flu vaccine.

People can help prevent the spread of flu by washing their hands frequently and thoroughly, avoiding touching their eyes, nose and mouth with their hands and staying home when sick.
