It’s been a rough couple of weeks for the Windsor Skilled Nursing and Rehabilitation facility, operated by Integritus Healthcare of Pittsfield. Since February 21, 75 residents have come down with Covid-19, as well as 20 staff members. Five of the infected residents did not survive. In recent days, the infection numbers have dropped significantly, said Lisa Gaudet, Vice-President of Communications for Integritus -- down to 21 resident cases and 15 staff cases as of Monday, March 6. The facility expects that, at this rate, Covid should be cleared from the nursing home by March 15.
