The zones are categorised based on the number of cases in a district - green for areas with zero cases, yellow for areas with one to 20 cases, orange for areas with 21 to 40 cases, and red for areas with more than 41 cases.

Ministry to review zone classification method

During Health director-general Dr Noor Hisham Abdullah's press conference aired live on 8 April, he said that the ministry is looking into the way the zones are classified.

So far, the ministry has been calculating cases in a certain area collectively, so recovered cases and such were not taken into consideration when the zones are classified. “This way at some point, all areas will become red zones,” he said during the press conference.

He added that the ministry is looking at analysing the situation on two-weeks basis to determine how prevalent COVID-19 is in an area.
