There have been another 100 flu cases reported in Genesee County in the past two weeks, bringing the season total to 250.
At this point in the season last year, said Public Health Director Paul Pettit, there were 53 confirmed cases.
The flu season started Sept. 1.
The local increase in flu cases is consistent with reports of more flu cases all over the country.
Pettit encourages everybody who has not been vaccinated to get vaccinated. There are reports that this year's vaccine is less effective against the most common strain of flu this season, but it does work on other strains and health officials say the vaccination will lessen the severity of symptoms.
