The newspapers are reporting large numbers of migrant workers (Cambodians, working legally or illegally in Thailand) who are now daily streaming across the Thai-Cambodian border, legally or illegally. They earn about $10 or $11 a day in Thailand (which gives you a clue how low their pay would be if they were in Cambodia because they’re going to Thailand to get more money than here) but now there is a spike in coronavirus infections in Thailand and the workers are afraid for their personal safety and also many of the businesses that employed them have closed so there are no jobs.
This presents quite a problem for Cambodia because more than 80 of the returnees have tested positive. That’s one sixth of all the cases in the kingdom. And those are the ones who crossed at the legal checkpoints and were tested. Others sneak in through the jungle because they don’t want to be quarantined. It could be a perfect setup for a major infection in Cambodia.
