A Boston Public Health Commission report shows higher rates of positive tests for Covid-19 in Hyde Park, Mattapan, parts of Dorchester and East Boston than the rest of the city - with Hyde Park showing the highest rate - one that is more than double that of neighboring West Roxbury.

The data, current through April 2, also shows that roughly 45% of the city's 1,232 diagnosed cases as of mid-day on April 2 have been in people under 40 - and that the numbers are roughly equal between men and women. The vast majority of cases were in people who stayed at home; only 96 required hospitalization. Some 6% of the cases - 68 in all - were among healthcare workers living in Boston.

So far, 10 Bostonians have died from Covid-19 complications.
