Rhode Island Health Director Michael Fine says the flu is officially widespread in the state.  Fine's declaration means that all healthcare workers who are not immunized must wear surgical masks when seeing patients.  Even those who had a flu shot this year may not be safe, as the vaccine is not well matched to this year's flu strain.  Hundreds of people die each year in the state from the flu, and Fine is urging anyone who has not been immunized to get a shot immediately, as it's still the best way for people to protect themselves.
