BOSTON (The Boston Globe) — Public health officials say the number of people in Massachusetts who have tested positive for the new coronavirus more than doubled on Sunday to 28, up from 13 on Saturday. The state Department of Public Health said all 15 of the new cases had a direct connection to a meeting of the biotech firm Biogen held for company employees at a Boston hotel last month. The new cases include eight men and seven women. Most of them live in the greater Boston area. They range in age from in their 30s to 60s. All are in isolation at home.
