The flu is currently making its way across Iowa, and it's already killed multiple people.

The Daily Nonpareil reports:

112 of the flu cases have lead to hospitalization so far. Although none have been reported in Scott County, the rate of positive tests in Eastern Iowa is rising, says IDPH's weekly flu report. Additionally, respiratory syncytial virus (RSV), an illness that can be fatal in children, is also prevalent in Eastern Iowa, with 41 percent of Rapid RSV tests coming back positive in the last week.

So what exactly falls under the umbrella of "the flu?"

According to the Department of Public Health, the flu is a respiratory illness that's caused by a virus. Symptoms vary, but usually include headache, fever, lethargy, congestion, cough, sore throat, and body aches.

The elderly and small children are the most at risk of death from the illness.
