A spate of mysterious second-time infections is calling into question the accuracy of COVID-19 diagnostic tools even as China prepares to lift quarantine measures to allow residents to leave the epicenter of its outbreak next month. It's also raising concerns of a possible second wave of cases.
From March 18-22, the Chinese city of Wuhan reported no new cases of the virus through domestic transmission — that is, infection passed on from one person to another. The achievement was seen as a turning point in efforts to contain the virus, which has infected more than 80,000 people in China. Wuhan was particularly hard-hit, with more than half of all confirmed cases in the country.
But some Wuhan residents who had tested positive earlier and then recovered from the disease are testing positive for the virus a second time. Based on data from several quarantine facilities in the city, which house patients for further observation after their discharge from hospitals, about 5%-10% of patients pronounced "recovered" have tested positive again.
Some of those who retested positive appear to be asymptomatic carriers — those who carry the virus and are possibly infectious but do not exhibit any of the illness's associated symptoms — suggesting that the outbreak in Wuhan is not close to being over.

Did you see where Smallbury suspended all recycling except cardboard, to protect their employees. Do they not know that the virus lives long on paper and cardboard?
I wonder how they come to these decisions?
Better than Worcester. Your on your own in public works there. No directives on safety at all. Oh, but the commissioners are having social distancing meetings with cameras. Of course they're more important than the peons digging thru trash.
The county gets all of the city's collected recyclables except cardboard. The county has shut down its recycling, therefore there's nowhere for the city of Salisbury to take residents' recycled glass, plastics, aluminum and bi-metal cans.
The choices are to keep the recyclables until the bans are lifted, or put them in regular trash for pickup and burial at Mt. Wicomico.
Thank you for helping people figure this out. It's very simple, protect others throw recycle in the trash until this ends.
