MANILA, Feb 22 (Mabuhay) –Positivity rate in the National Capital Region (NCR) has decreased to 4.9%, lower than the recommended 5% of the World Health Organization, according to OCTA Research on Tuesday.

The independent monitoring group said this is the first time the positivity rate in the region decreased to less than 5% since December 26, 2021 prior to the COVID-19 surge caused by the more transmissible Omicron variant.

NCR remained at “low risk” classification for COVID-19 with an average daily attack rate (ADAR) of 2.85 and a reproduction number of 2.85.

Reproduction rate refers to the number of people infected by one case. A reproduction number that is below 1 indicates that the transmission of the virus is slowing down.

ADAR, on the other hand, pertains to the incidence showing the average number of new cases in a period per 100,000 people.

Meanwhile,  Batangas, Cavite, Laguna, Rizal all remained at “low risk” classification, according to OCTA Research.

Quezon, meanwhile, is now at “very low risk” for COVID-19, it said.

Data from OCTA showed that ADAR in Quezon was at 0.51 per 100,000 individuals while its reproduction number was at 0.18. Its growth rate was recorded at -40%. All are considered very low.

According to, a region’s overall risk level is based on its ADAR. Low risk means an ADAR of less than 1 per 100,000 population.

Otherwise, the overall risk level reflects the highest risk level across the three metrics such as the ADAR, infection rate, and test positivity rate.

NCR mayors will meet on Tuesday night to discuss if the alert level in the region could already been downgraded from Alert Level 2 to 1 in March. (MNS)
