China's Wuhan Increases COVID-19 Testing—Fearing Second Wave

According to Reuters, authorities in Wuhan, China have tested over 3 million residents for the coronavirus.
The tests occurred in April and May. The city is the epicenter of the original outbreak and new infections recently popped up.
The city plans to conduct more tests for the rest of its 11 million residents over a period of just 10 days.
Testing priority will be given to those who have not yet been tested, people living in places with previous cases of infection, old and densely populated estates.
Wuhan reported a second cluster of cases after their city reopened on April 8.
The infections were previously asymptomatic -those who had COVID-19, but showed no fever or other symptoms.
