KUNMING -- Ruili, a border city in Southwest China's Yunnan province, now has no medium- or high-risk areas for the novel coronavirus, the city's COVID-19 prevention and control headquarters announced on May 4.

COVID-19 risk levels in two areas of the city were downgraded from medium to low from 8 pm Tuesday, marking the clearance of all areas with medium or high infection risks in Ruili.

Dozens of domestically-transmitted COVID-19 cases have been reported in Ruili since March 30. Local authorities launched several citywide COVID-19 testing campaigns to curb the spread of the virus.
