BANGKOK — Thailand’s government says it is tightening restrictions aimed at stopping the spread of the coronavirus as the country logged another 527 new cases.

Officials said Tuesday that foreign migrant workers accounted for 439 of the new infections, while 82 were Thais infected locally and another six were new arrivals from abroad. Thailand on Monday reported 745 infections, the most since the pandemic began.

After almost no locally transmitted infections for almost half a year, Thailand in recent weeks has seen a viral resurgence first spotted in communities of foreign factory and market workers just outside Bangkok.

The government has responded by putting in place fresh antivirus measures across large parts of the country, including closing schools and limiting restaurant hours. The government said Tuesday that it will restrict travel between provinces in so-called “red-zone” to goods, cargo and necessary travel. Field hospitals were being set up in at least five hot zones.
