The Boston Public Health Commission reports 35 Covid-19 cases in Boston this month have been traced to the outbreak in Provincetown - most in people who had been fully vaccinated.
Because of that, the commission today recommended that anybody who's visited Provincetown since July 1 - or who plans to in the near future - self-isolate and stay away from gatherings or groups for at least five days, even with complete vaccination. And then, get a Covid-19 test - and keep self-isolating until you get back a negative result.
Close, sustained contact with other people indoors increases your risk of exposure to COVID. While those vaccinated are strongly protected from serious illness or hospitalization, it is still possible to get COVID and spread it to others.
The commission did not say how severe any of the Boston cases were.
