State figures out tonight show that Boston is now seeing 11.1 new daily Covid-19 cases per 100,000 residents, the third week in a row the city has been in the state's "red" zone - and an increase from last week's rate of 10.0.
The number is important not just because it shows a continuing growth in the number of daily Covid-19 cases in Boston, but because three weeks in "red" is the figure recommended by state education officials to move all public-school classes to online-only instruction.
Mayor Walsh and School Superintendent Brenda Cassellius last week delayed an expansion of the BPS "hybrid" system - in which more students could return to school for part of the week - from tomorrow until Oct. 22 because of rising Covid-19 numbers. Currently only special-needs, ESL and homeless students or students under the care of DCF, who were already spending some time in schools
The 11.1 rate represents roughly 77 new Covid-19 cases a day in Boston. For the two weeks ending Aug. 12, Boston was seeing about 49 new cases of Covid-19 per day. And for the two weeks ending July 20, Boston was seeing about 20 new cases a day.
Even the most current figures are still far lower than during the "surge" days in April and May, but some experts have cautioned that only means we need to continue to be careful and do things such as wear masks, wash hands frequently and avoid large gatherings, to keep another surge from exploding.
Boston Public Health Commission figures for Covid-19 tests show that for the week ending Oct. 10, 4.4% of tests came back positive, up from 4.1% the week before.
The city figures do show some good news: The rate at which East Boston residents are testing positive for the virus has been dropping steadily, from close to 14% of tests being positive several weeks ago to 6.5% for the week ending Saturday. But 02125 in Dorchester and 02121, which covers parts of Dorchester and Roxbury, now show a positivity rate of 9.7%. And Hyde Park was at 9.1%.
