Health officials say the H3 strain is different from the most common strain this season and is causing an increase of the flu in the state.
Director of Health Michael Fine says this year's flu vaccine protects the H3 strain and other strains, and it's not too late to get vaccinated. Fine says getting vaccinated not only protects you but also those around you, including senior citizens who are now the most vulnerable.
State officials say two people in Rhode Island have died and 295 people have been hospitalized because of the flu this flu season.
