上海加强疫情防护措施 - 2021年04月07日

Shanghai has tightened its COVID-19 prevention and control measures on people from domestic high- and medium-risk areas, authorities said on Tuesday after Ruili, a city in southwest China's Yunnan Province, enlisted three high-risk areas.
People from high- and medium-risk areas should inform their residential or village committees, working units or hotels immediately or within 12 hours after arriving in Shanghai, according to the city's epidemic prevention and control authorities.
Anyone arriving from a high-risk area is required to have two nucleic acid tests and quarantine for 14 days at designated venues for observation.
