October marks the official start of flu season, and already sporadic cases are appearing in Minnesota. 

The state health department's first weekly influenza report released Thursday three confirmed flu hospitalizations and one outbreak of influenza-like illness in a school.

Light flu activity is typical in October and does not necessarily signal an early start to the season. But health officials say flu cases can surge at any point, so people shouldn't delay getting vaccinated. 

The influenza that's circulating in the Midwest right now is primarily a strain that's harder on elderly people said Karen Martin, an epidemiologist at the Minnesota Department of Health.

"But it's really to early to say what kind of season it's going to be," she added.

In Minnesota, more than 1,500 people were hospitalized for flu last season. Three children died.

Those at a higher risk of flu complications include seniors over age 65, young children, pregnant women and people with chronic health conditions such as asthma, diabetes or heart disease. 

Public health officials are concerned that vaccination rates could drop this year because the nasal mist form of the flu vaccine is not available. 

In June, a U.S. Centers for Disease Control and Prevention advisory board discouraged health providers from using FluMist. The recommendation is based on government data showing the nasal mist offered poor or no protection against flu in recent seasons.  

Deemed ineffective, FluMist is nixed in favor of vaccines

So, once again, shots are the only option. 

"You know it's too bad for those people who didn't like injections that they're not able to get the FluMist this year," said Martin. "But we're hoping that people understand that influenza is a serious disease and will continue to get vaccinated."  

Last year flu vaccination rates dipped after researchers reported that the previous season's vaccine was a very poor match to circulating flu strains. 

Because flu vaccines are not 100 percent effective even in the best of circumstances, Martin said flu prevention strategies should always include good health habits.

"We really still encourage good hand hygiene and staying home from work and school when you're sick," said Martin.
