Health director-general Dr Noor Hisham Abdullah has reiterated his call for all Malaysians to observe a two-week "self-lockdown" even without the formal government declaration initially expected to be announced today.

Speaking during a joint press conference with Senior Minister Ismail Sabri Yaakob, Noor Hisham said the two-week period would assist the ministry in efforts to break the Covid-19 infection chain.
