Without CMCO, Four Million Klang Valley Residents Could Have Contracted Covid-19: MOH

MOH reported 2,018 new Covid-19 cases today, the third-highest daily record, pushing Malaysia’s cumulative infections to 95,327.

KUALA LUMPUR, Dec 21 — Four million residents in the Klang Valley, or two-thirds of the region’s population, might have been infected with Covid-19 if a Conditional Movement Control Order (CMCO) was not imposed, health authorities claimed today.

Health director-general Dr Noor Hisham Abdullah said the Ministry of Health’s (MOH) projection was based on an infectivity rate, or R0, of 2.2. An R0 of 2.2 means each Covid-19 case on average leads to another 2.2 new infections.

Dr Noor Hisham only revealed this projection today, more than two months after the CMCO was first implemented in the Klang Valley on October 14.

Back on October 12, he said MOH had advised the government to implement a CMCO in Malaysia’s economic centre to prevent yellow zones from turning red, even as the Klang Valley back then was reporting fewer than 100 Covid-19 cases a day.

Based on MOH’s Covid-19 case modeling, in the week before October 12, the trend of daily Covid-19 cases (average 468 a day nationwide) still fell below an R0 of 0.95. The highest projected R0 value in MOH’s model was 1.50.

“If we look back when Covid happened in Sabah, we predicted that in the Klang Valley, cases would rise. At that time, we predicted the R0 was high in the Klang Valley, and our action was proactive, which was to do a targeted CMCO on October 14,” Dr Noor Hisham told a press conference today on Malaysia’s Covid-19 cases.

“If we didn’t do the CMCO, our projection was maybe we’d get four million residents who would be infected. We used an R0, or infectivity rate, of 2.2. But with the CMCO, we reduced the R0 to 0.97 as of now. So our objective is to reduce it further to 0.5 or 0.4.”

He added that movement restrictions were imposed in the Klang Valley two months ago because of high population density, people’s movements, and a concentration of migrant workers. The Klang Valley has an estimated six million residents.

Dr Noor Hisham said the Covid-19 situation in Sarawak has been improving, with a state R0 of 0.4.

“If it reduces to 0.4, then we can flatten the curve.”
