BANGKOK (AP) — Faced with a sharp rise in coronavirus cases, the Thai capital on Sunday announced a ban on indoor dining and gatherings of more than 20 people, in addition to the closure of construction sites and the sealing off of workers’ quarters in Bangkok and nine other provinces. The measures will remain for 30 days. Thailand reported 3,995 confirmed cases and 42 dead in the last 24 hours. The numbers have doubled recently, and health officials blame a lack of cooperation from migrant workers employed in construction and in factories. The situation has become critical as the number of hospital beds in Bangkok for seriously ill COVID-19 patients is running short despite the creation of several field hospitals. Prime Minister Prayuth Chan-ocha said Friday that a proposal for a seven-day curfew for all of Bangkok has been rejected for the time being. Under the new restrictions, construction workers will be isolated in camps in Bangkok and five neighboring provinces, and in the country’s four southernmost provinces, all virus hotspots.
