The Ministry of Health on March 1 recorded 15 more cases of Covid-19, all but one of which were linked to the February 20 community transmission.
The cluster cases include one Cambodian and 13 Chinese nationals, five of whom stayed in Preah Sihanouk province and are receiving treatment there. These bring the country's third community transmission cases to 316 in just over a week.
The only imported case is an Indonesian man who registered his address in Sampov Loun commune in Kandal province's Koh Thom district and arrived from Indonesia via Singapore on February 26.
The man was travelling with 71 other passengers, all of whom tested negative and are being quarantined in the capital.
The latest cases bring the Kingdom's Covid-19 tally to 820, with 477 having recovered and been discharged from hospitals.
