Wuhan has announced  only 3 new confirmed cases since March 18. Restrictions on travel were lifted after a 77 day lockdown on the city, allowing inbound and outbound travel. Some restrictions on housing complexes have been tightened after reports of dozens of asymptomatic cases. The number of asymptomatic cases remains unknown. There is a fear of a second outbreak and authorites are staying vigilant, as it is feared that the first outbreak was worse than previously thought.

Epidemiologists, intelligence agencies, and health experts believe the number of cases reported in Wuhan and China are undercounted. This could be they say a result of local officials wanting to present a better picture, of not enough testing in the early stages, not counting people who died at home, and including people who died of pneumonia under pneumonia instead of coronavirus. Dr Birx, head of the U.S. response effort,  says the U.S. lists people who died of pneumonia in New York as coronavirus deaths because of how widespread it is there, hitting seven people in a thousand.

In addition there is a problem for all countries in counting people without symptoms. No one even knows how big that is, and Dr Birx in the U.S. says it is important to find out.
