YANGON, Myanmar —- Myanmar health authorities have reported 743 new confirmed cases of the coronavirus, bringing the country’s total over the 10,000 mark.

The Health Ministry has announced a total of 10,734 coronavirus cases since March, including 226 deaths. There were 28 new deaths recorded Sunday.

Myanmar’s biggest city, Yangon, tightened lockdown measures last week. Residents cannot travel outside their officially designated wards. Police on Monday were manning checkpoints to ensure that vehicles driving through have valid exemptions such as medical reasons.

Most businesses must have their employees work from home and many factories are closed. There are exemptions to the restrictions for services deemed essential, including banks, petrol stations and food production.

The authorities have said there is a pressing need for increasing the capacity of quarantine centers and hospitals and other COVID-19 treatment facilities, and upgrading hospital staffing and equipment.
