The OCTA Research Group on Monday, Feb. 20 said the seven-day positivity rate for Covid-19 in Metro Manila has slightly increased.

In an update posted on social media, OCTA Research fellow Dr. Guido David said Metro Manila’s positivity rate had a “negligible” increase, from 1.6 percent on Feb. 11 to 1.7 percent on Feb. 18.

David pointed out that the positivity rates in Metro Manila, as well as in other major provinces, remained “low” at less than 5 percent.

Positivity rate refers to the number of individuals who yielded positive results from those who were tested for Covid-19.

The World Health Organization has recommended a positivity rate of 5 percent or less to show that the spread of the virus is under control.

The Department of Health on Sunday, Feb. 19 reported 50 new Covid-19 cases in Metro Manila.
