The Kingdom on Saturday saw two more cases of coronavirus infections, bringing the total to 53.
While the majority of the previous cases are linked to a Muslim religious gathering in Malaysia, the latest cases involved two French tourists visiting Sihanoukville.
The Ministry of Health said the pair, aged 67 and 80, were due to leave the Kingdom on Saturday, only to be found positive for Covid-19. They are being treated at the provincial hospital.
In a separate case, a disabled British woman aged 65 who was suspected of having contracted the virus tested negative twice on Saturday and will be discharged from the Royal Phnom Penh hospital in the capital on Sunday.
Of the 53 cases recorded thus far, 25 were found in Cambodian Muslims, of whom 23 had recently returned from the same religious gathering in Malaysia. The other two contracted the virus from their husbands.
