Two more areas have been declared as COVID-19 red zones, after registering high number of the virus infection cases.

According to the Health Ministry, the areas are Sepang in Selangor and Kota Samarahan in Sarawak, which had registered 46 and 42 cases respectively.

The latest addition brings the total number of red zones in the country to 23, with Lembah Pantai topping the list with 412 cases.

Sepang is the fifth red zone in Selangor, while Kota Samarahan is the second in Sarawak, since the outbreak.

A location is designated as a red zone if it registers more than 40 COVID-19 cases.

All districts in Kuala Lumpur were declared red zones last Sunday.

A green zone, meanwhile, is a district which has zero recorded COVID-19 cases. A yellow zone is one between 1 and 20 recorded COVID-19 cases, while an orange zone has between 20 and 40 recorded COVID-19 cases.

Yesterday, Defence Minister Ismail Sabri Yaakob said that the government is preparing a guideline to be applied on colour-coded zones.

For example, he said, certain leeway maybe given to people in green zones, once the Movement Control Order (MCO) is lifted.

The MCO was enforced on March 18 and was supposed to last until March 31, before it was extended to April 14.

There are 3,963 confirmed COVID-19 cases in Malaysia, with 63 deaths, as of Tuesday evening.
