States like Sabah, Kelantan, Melaka, Labuan, Putrajaya, Pahang, Perak, and Sarawak have recorded Rt levels above 1 as of April 4, which means that the Covid-19 outbreaks there are growing.
Areas with high Covid-19 prevalence were originally placed in the fourth phase of the national vaccination programme, before they were brought forward to the second phase, says Dr Adham Baba.
A positivity rate of above 5% in a locality or cluster indicates the possibility that more people infected with coronavirus in the community haven’t been tested yet.
