The Centre for COVID-19 Situation Administration says it will punish large factories that have not completed preventative measure assessments by 15th June.
Only 650 of 3,300 large factories across the country have completed a required assessment of sanitation at their premises.
The CCSA wants these assessments to help with its containment of the virus and companies will be punished if they refuse to cooperate.
The factories have also been warned they must complete the survey with direct answers. If they fail the assessment, training officers will visit to improve their conditions.
CCSA assistant spokeswoman Dr Apisamai Srirangson said that over the past two months, more than 200 workers in large factories across 10 provinces had caught the virus due to overcrowding, poor ventilation and too few sanitiser points.
“The disease is spreading through factories,” Dr Srirangson said, adding that infections among Cambodian workers were 3.9 times higher than among Thai nationals at the same plant – 275 of 1,637 Cambodian workers had COVID-19, a rate of 16.8%. Meanwhile, only 206 Thais out of 4,213 had the disease, a rate of 4.9%.
Cambodian workers lived in dormitories at their workplace while their Thai colleagues lived at home or in nearby dorms. The Cambodians’ living quarters were crowded, with 3-6 workers in each room, Dr Srirangson said.
