The health ministry reported 4,855 new cases — the highest since Jan 31 — and 27 deaths. It has seen a total of 458,077 coronavirus cases and 1,788 fatalities.

Malaysia declared a nationwide lockdown on Monday, prohibiting inter-district travel and shutting down schools. It has been under a state of emergency since January to curb the spread of the virus, according to Reuters.
