Governor Charlie Baker is warning that a more contagious strain of Coronavirus is likely already in Massachusetts.
Baker says the more contagious form of the virus threatens to bring a new surge of cases in the state.
He says this makes it more important than ever that everyone in the state always wears masks in public and practices social distancing.
While state officials are concerned about the new strain, experts say it is not uncommon for viruses to mutate.
