In most parts of the country, most illnesses right now are being caused by a flu strain that leads to fewer hospitalizations and deaths as the kind of flu that dominated a year ago, according to officials at the Centers for Disease Control and Prevention.
The H1N1 virus is also the predominant strain in the US this year.
In California, Fresno County has seen six flu-related deaths since October, the Fresno Bee reported on Friday, while a total of 42 lives have been lost throughout the state, according to the Los Angeles Times. Vaccines also work better against it, said the CDC's Dr. Alicia Fry.
Health officials recommend Hoosiers protect their families by getting a flu shot if they haven't already and to take precautions, including frequent hand-washing and covering their mouths when coughing.
The health agency also released new estimates of how the flu season is playing out.
-Roughly 70,000 to 80,000 have been hospitalized. Typically, the CDC waits until the end of flu season before calculating the estimates.
Some doctors and nurses were anxious going into this flu season, considering how bad previous year was, said Dr. James Steinberg, chief medical officer at Emory University Hospital Midtown in Atlanta.
