MPH. “Massachusetts has been preparing for a possible case of this new coronavirus, and we were fortunate that astute clinicians took appropriate action quickly. Again, the risk to the public from the 2019 novel coronavirus remains low in Massachusetts.”How does the virus spread? The virus is thought to spread from person to person through respiratory droplets emitted by coughing or sneezing — but it’s not clear exactly when a person becomes contagious. There’s currently no evidence that the virus is airborne — meaning, for instance, it doesn’t travel across a large room.
