BANGKOK — Thailand announced new restrictions to slow its spread but didn’t institute any curfews or lockdowns.

Thai health officials on Friday confirmed 1,582 new cases, raising the total number of confirmed cases to 39,038 and 97 confirmed deaths.

Infections have been surging to record highs almost daily since early April. Most of the new cases involve the virus variant first found in Britain.

New nationwide protective measures take effect nationwide Sunday for at least two weeks. They include restrictions on school, no gatherings of more than 50 people and closing of bars.

Inter-provincial travel is not banned, though some provincial authorities have ordered testing of arrivals.

Prime Minister Prayuth Chan-ocha suggested harsher measures could cause economic hardships.
