APTOPIX Virus Outbreak China

In this March 18, 2020 photo released by China’s Xinhua News Agency, people applaud as departing medical workers enter Wuhan Tianhe International Airport in Wuhan in central China’s Hubei Province. Last month, Wuhan was overwhelmed with thousands of new cases of coronavirus each day. But in a dramatic development that underscores just how much the outbreak has pivoted toward Europe and the United States, Chinese authorities said Thursday that the city and its surrounding province had no new cases to report. The virus causes only mild or moderate symptoms, such as fever and cough, for most people, but severe illness is more likely in the elderly and people with existing health problems.
