I'm confident Wuhan does not have community spread of Coronavirus. To eliminate the virus, China tested all 11 million residents of Wuhan for coronavirus in just 14 days [1]. That's more than 500,000 people per day. Dozens of asymptomatic carriers were found, who were then quarantined. Wuhan hasn't had new cases in weeks.
China used a similar mass testing strategy in Beijing. When an outbreak appeared at the Xinfadi wholesale market in June [2], the government had a short (several weeks long) lockdown and tested more than half the city's population. Some days they did ~400,000 tests per day [3]. This was possible because they sent in testing resources from across the country to Beijing. The outbreak was eliminated within a month.
I believe mass testing is an effective way to reign in the coronavirus. It's impossible to have a widespread outbreak if you preemptively test and isolate all carriers.
