Massachusetts Data Update September 17,2020

The positivity rate for newly tested people dropped back to 2.0% today after reaching 2.2% several days ago, primarily from today’s newly reported data  (1.5% positive on a large number of tests). Suspected cases have increased quite a bit over the past week (almost 30 per day compared to 10 a day the week before), which explains the widening difference between the confirmed case positivity rate and the confirmed plus suspected case rate. Testing is leveling out, and repeat testers are now over two-thirds of those tested.  The number of newly tested people is lower than last week and one month ago.

Test Positivity Rate (All Tests)   0.8% 0.9% 1.3%
Test Positivity Rate (Newly Tested)   2.0% 2.1% 1.6%
Test Positivity Rate (Repeat Testers)   0.2% 0.3% 0.7%
Percentage Repeat Testers   67.3% 65.3% 32.7%

All Tests (Lagged 1 Week)   43,096 42,140 22,780

And the beat goes on.  Hospitalization data remains basically unchanged from a week or month ago, except for a minor decline in the total number of patients hospitalized.

New Confirmed Patients   19 21 20
         
Percent ICU / Hospitalized   19% 16% 17%
Percent Intubated / ICU   37% 43% 41%

Unfortunately, after a brief decline, the percentage of deaths from long-term care facilities has begun to climb again.  The case increase is clearly from increased test positivity, as the number of newly tested people is roughly the same as four weeks ago, and substantially less than last week.
