Sabah recorded the highest number of cases, with 25, including 17 from the Benteng LD cluster in Lahad Datu.
Only one case was reported in Kedah while the Bunga cluster in Negeri Sembilan also recorded four cases, involving ship crew members.
The new infections bring the number of cases to 9,946, health director-general Dr Noor Hisham Abdullah said in a statement.
Seven patients were discharged today, bringing the total number of recoveries to 9,203.
There are 615 active cases currently, with 11 admitted in the intensive care unit and five patients requiring respiratory assistance.
No new Covid-19 related deaths were reported, leaving the death toll at 128.
The three imported cases involved two Malaysians and an Indonesian who entered the country from Indonesia.
Meanwhile, the local cases involved 19 citizens and nine foreigners.
Four of the local cases in Sabah, outside of the Benteg LD cluster, were detected during a severe acute respiratory infection screening at Hospital Lahad Datu, a pre-operation screening at Hospital Kudat, a referral screening at Hospital Tawau and a screening on a senior citizen at Klinik Kesihatan Merotai.
Another local case was detected from close contact screenings, while a prisoner at the Kudat police headquarters also tested positive for the virus.
The case in Kedah is linked to the Sungai cluster, bringing the total number of infections there to 57.
The four new cases from the Bunga cluster were from second screenings on 22 crew members of a ship that has been docked in Port Dickson. This brings the total number of cases to 10.
The Benteng LD cluster has recorded 420 positive cases in total, comprising 185 Malaysians and 235 foreigners.
Noor Hisham called on residents of the Kota Setar district, which is under an administrative enhanced movement control order (EMCO), to cooperate with the authorities in preventing the spread of the virus.
He also urged them not to go outside their homes unless it is absolutely necessary.
