Coronavirus Local Impact

CHICOPEE, Mass. (WWLP) – For nearly two months now the percent positivity rate in Massachusetts has slowly been rising. 22News looks at those numbers and explains how it is calculated.

On August 10, the Massachusetts Department of Public Health reported the 7-day average of percent positivity is 2.91%, with 146 positive cases out of 8,103 molecular tests. The percent positivity rate has been increasing daily since June 26 with the lowest rate since the beginning of the pandemic at 0.31%, with 72 positive cases out of 13,281 molecular tests.

The last time Massachusetts was over 3% for a percent positive rate was in February of this year. The highest the percent positive rate has ever been in Massachusetts, once testing became more available to the public, was April 13, 2020 with 28.22%

The 7-day average of percent positivity is 2.91%

COVID-19 Molecular Test:

The percent positivity rate is calculated using molecular tests only. Percent positivity is calculated by dividing the number of positive tests by the total number of tests during the time period.

  • 0-4 years: 5.31%
  • 5-9 years: 6.12%
  • 10-14 years: 5.96%
  • 15-19 years: 20.30%
  • 20-29 years: 18.25%
  • 30-39 years: 14.19%
  • 40-49 years: 5.79%
  • 50-59 years: 11.59%
  • 60-69 years: 7.20%
  • 70-79 years: 3.03%

The DPH reports the positive tests by age group of Massachusetts residents weekly. The highest age group of all the positive tests conducted for the week of August 8 were ages 15-19 years, accounting for 20.30% of those positive tests. This is not the same as percent positivity.

The most common kind of molecular test is a PCR test. This diagnostic test identifies the presence of virus’s genetic material. These tests are very accurate and a positive result means someone has a current COVID-19 infection.
