"The flu can be severe enough to take a life so we have to take it seriously for sure", Ross said.

There were 10,313 confirmed cases of influenza in the 2018-19 flu season in Maine.

The flu season generally begins in October or November, peaks between January and February, and can last as late as May.

Getting the shot can reduce flu illnesses, doctor visits, missed work and school due to flu, as well as prevent flu-related hospitalizations. A year ago during this time there were 16 pediatric deaths. However, Indiana has not seen any pediatric deaths yet. A/H1N1 (pdm09) is the other main circulating strain, and Piedra said that "older folks have a lot of immunity against that type of virus". "There are more children who have died [this year] at the same point in time as previous years".

The most common strain so far this season is influenza A H1NI, accounting for about 60 percent of cases, followed by influenza B (Victoria) strain at roughly 35 percent.

According to the newest updated stats from the Centers for Disease Control and Prevention (CDC), there's just a 58% match with B/Victoria viruses-aka, one of the most common viruses out there right now, representing nearly 98% of circulating influenza B strains.

So far, 32 children have died from flu-related illness in the 2019-2020 flu season, including 21 deaths associated with influenza B viruses and 11 with influenza A viruses. Health experts believe the increased number of deaths has to do with the type of Influenza that is circulating. "Almost every year, one of the viruses is not perfectly matched".

You can get your flu shot from your healthcare provider, at many local pharmacies, or at Public Health Department clinics. "We tell people if you get the flu vaccine, you will have a 50 percent less chance of getting the flu". "People transmit it by coughing and sneezing in public", Alvarado says.
