According to new Caixin reporting (in Chinese; in English), there are new asymptomatic cases of COVID-19 in Wuhan, often numbering “more than a dozen a day,” that are not being reported in official numbers. The widely criticized policy of not including asymptomatic cases in official numbers in China has been in effect since February 7, according to previous Caixin reporting.
This is worrying, because “the number of ‘silent carriers’ — people who are infected by the new coronavirus but show delayed or no symptoms — could be as high as one-third of those who test positive, according to classified Chinese government data” that the South China Morning Post claims to have seen. Earlier World Health Organization estimates, based on Chinese data, had downplayed asymptomatic transmission.

The SCMP also has a report with more information on one case of asymptomatic COVID-19 in a district in Wuhan:
Qiaokou authorities said a 62-year-old man from the district was tested for the pneumonia-like illness three times — he was negative on Tuesday, positive on Thursday, when he was admitted to hospital, but tested negative again on Friday.
The man did not have symptoms such as a fever or cough so was not counted as a confirmed case, according to a statement.
Nevertheless, Wuhan is loosening its lockdown, allowing some residents to return to work and gradually reopening public transportation, per the Guardian. Shanghai has also lowered its emergency alert level, per Reuters.
