There are 15 new presumptive positive cases of coronavirus in Massachusetts, the state's Department of Public Health announced Sunday.
Of the presumptive positive cases announced today, eight are men and seven are women. Five are from Suffolk County, five are from Middlesex County and another four are from Norfolk County. The number also includes a woman whose place of residence DPH could not confirm, according to a statement.
In all, 23 of the 28 Massachusetts residents with coronavirus attended the biotech company's conference, held last week at the Marriott Longwharf in Boston and attended by roughly 175 people. Of the remaining five cases, three are connected to travel to northern Italy, one is connected to travel to China, and one has no known connection to either travel or the conference.
Two international workers for Biogen, along with a Tennessee man and two Indiana residents, also were found to have the virus after attending the conference.
Worldwide, the coronavirus has infected more than 108,000 people and killed more than 3,600, the vast majority in China. Most cases have been mild, and more than half of those infected have recovered.
The DPH said the risk of coronavirus to the general public in Mass. remains low at this time.
