Shanghai has built about 15,000 nucleic acid sample collection sites across the city for its normalized COVID-19 prevention and control.

These PCR sample collection kiosks have been set up at local residential communities, office buildings, industrial parks, near Metro stations and transport hubs, said Zhao Dandan, deputy director of the Shanghai Health Commission.

They include about 4,000 spots for residents at local communities, about 6,000 for companies, schools and construction sites, as well as about 5,000 for any citizen, Zhao told the city's daily press briefing on Monday.
