The Ministry of Health on Friday night confirmed four more cases of coronavirus infections, bringing the total to 51.
One of the four infected persons, a 39-year-old Malaysian Islamic preacher from Kampong Cham province's Kang Meas district, is being treated at the provincial hospital.
In Phnom Penh, a 33-year-old Cambodian man from Russei Keo district's Chhrang Chamres II commune is being transferred to the Chak Angre Health Centre in Meanchey district for treatment.
The ministry said the man was not among the 79 who attended the Muslim religious event in Malaysia but had direct contact with them.
The other two men, aged 38 and 48 from Battambang province, are Cambodians who recently returned from the same Muslim gathering in Malaysia. Both are being treated at the provincial hospital.
