The same flu strain that caused the 2009 flu pandemic is back again this year.
Angela Minicuci is a spokesperson for the state Department of Community Health.
She says everyone should be protected from H1N1, not just those considered high-risk, like the elderly, pregnant women, and people with chronic illnesses.
"What we are seeing is that people who are otherwise healthy adults, people we wouldn't typically think would be seriously affected by coming into contact with the flu virus, are in fact being hospitalized," says Minicuci. "We've already had a number of deaths occur in both children and adults in Michigan."
Minicuci says it is not too late to get a flu shot.
It is not possible to get the flu from the shot, because it uses dead virus. This year's vaccine does include the H1N1 strain, so it offers good protection from the flu that is out there.
At least six adults and one child have died of the flu already this year in the state.
