COLOMBO, Sri Lanka — Sri Lanka has confirmed that more than 300 garment factory workers have been infected with the coronavirus, after reporting its first community infection in two months.

The health ministry said 321 cases have been identified in the cluster as of Tuesday after the first patient was diagnosed at a hospital two days ago.

To contain the outbreak, the government imposed a curfew in two suburbs of the capital where the majority of patients live, closed schools and universities, and imposed restrictions on public transport.

For more than two months, Sri Lanka health officials have said they have prevented a community spread of the virus and that all diagnosed patients had belonged to two known clusters.

The country has reported 3,471 patients with 13 deaths. Of the total patients, 3,259 have recovered.
