Authorities have not identified the 4-year-old, who died outside of the county, according to a news release from the Riverside University Health System-Public Health.
That year, Clark County didn't enter active flu season until the end of January, and stayed above the 10 percent threshold until spring. About 80 percent of the children who died didn't receive a flu shot.
In contrast, H1N1 tends to target children and younger adults more than seniors - and flu-trackers like Skowronski say this season is no exception.
Just last week, the Indiana Department of Public Health said flu activity is now "high" and "widespread" across the state. "We continue to recommend community members get their flu shot".
The flu is a contagious respiratory disease caused by influenza viruses and can cause mild to severe symptoms. "This is a tragic reminder that the flu can still kill and that children are particularly susceptible to the illness".
The best protection against the flu is the flu shot, but is it too late to get vaccinated? Healthcare workers should also get the vaccine to protect themselves and those that they care for. The 64-year-old man hadn't received his vaccination, according to the county.
Experts say it takes about two weeks to build up immunity against the virus after getting vaccinated. There were about 80,000 estimated deaths, including 180 children - the most since the CDC started using its latest surveillance procedures.
Dr Kelleher said that while most people will get better themselves from flu, anyone who was concerned about their condition should telephone their GP or an out-of-hours medical service so they could arrange to be treated in a way that did not put others at risk.
