MANILA – The slight increase in Metro Manila's Covid-19 positivity rate, average daily attack rate (ADAR), and reproduction rate was due to the holiday frenzy and not necessarily because of the Omicron variant, OCTA Research fellow Dr. Guido David said on Monday.

David said it is premature to say that the newest coronavirus variant had something to do with the spike in numbers.

Based on two-week growth rates (TWGR), David reported that the current reproduction number is at 0.85 percent while the ADAR in the National Capital Region (NCR) is at 0.82 percent.

The positivity rate slightly increased to 1.4 percent.

"So, hindi natin masasabi ngayon na Omicron-driven ito dahil nakita rin naman natin ito last year. Siguro doon sa pagtitipun-tipon ng mga kababayan natin kaya kailangan doble pag-iingat lang naman din ang kinakailangan natin (So we can't really say that it is Omicron-driven because we have seen this last year. The gatherings might have caused this, so we just really need to be extra careful)," he said in a media briefing.

As of Monday, the country has 9,579 active Covid-19 cases, the 10th straight day that the tally was below 10,000.

Four cases of the Omicron variant have been confirmed so far.

Just like last year, David noted that the Covid-19 testing slowed down as laboratories took a break and the recent onslaught of Typhoon Odette affected the operations of some testing centers.

He said a "clear picture" as to how the Covid-19 cases suddenly increased might be available until the first week of January next year.

"Ang nangyari naman noong January this year lang, noong January of 2021, iyong uptick ay bumalik na siya sa normal level. So bumaba ulit siya. Iyon iyong sanang gusto nating makita ngayon na after January, kapag na-resolve na iyong testing, iyong kakulangan natin sa testing at iyong mga closed laboratories ay bababa ulit sa normal levels ang bilang ng kaso. Iyan iyong gusto nating mangyari (So, in January this year, the uptick went back to its normal level. So it went down again. So, that's what we want to see after January [next year], if we resolved our backlogs in testing and in our laboratories, then the cases will go back to normal levels. That's what we want to happen)," David said.

David sees no need yet to increase restrictions or push for premature interventions.

"It could just be a holiday uptick, which means na after the holidays, possibly bababa din iyong number of cases and iyong positivity rate (it is possible that the number of cases and the positivity rate will go down)," he added.

David reminded the public to continue adhering to minimum public health standards and avail of Covid-19 vaccines. (PNA)
