On March 28, the government announced that all international arrivals had to stay quarantined at designated sites, but there were exceptions. International arrivals with transfer to Jiangsu, Zhejiang and Anhui provinces are not quarantined in Shanghai. Instead, they are taken directly to their destinations.
Seniors, juveniles, pregnant women, people with physical disabilities, those who need to take care of the elderly or children, or those who have underlying diseases can apply for quarantine at home.
