or communities "as needed". My parents live in a gated community at outer band of Shanghai. Sounds like they close off a part of the city, test everyone, quarantine for 2 days while waiting for the result, then 2 weeks quarantine if there are positive test in the community. But a week or two ago, they were tested every other day for 2 weeks, so essentially a 2-week quarantine. With the rumor of the city wide shutdown coming, there has been panic buying/hoarding past month.
