China reports 1 new virus case, no deaths

China reported one new case of coronavirus Tuesday and no deaths, marking three weeks since it recorded a COVID-19 fatality.

The National Health Commission said 395 people remained under treatment in the hospital, while 949 were under isolation and observation for suspected cases or after testing positive despite showing no symptoms.

The latest figures come as China strikes back against accusations from U.S. Secretary of State Mike Pompeo and others that the pandemic may have originated in a lab in the central Chinese city of Wuhan where it was first detected late last year.

The World Health Organization has backed up China's refutations and most experts believe the virus developed naturally among bats and was transmitted to humans via an intermediary animal, most likely the armadillo-like pangolin that is sold for human consumption in wet markets, including the one in Wuhan linked to the pandemic's origin.

China has reported 4,633 deaths from the virus among 82,881 cases, but strict travel restrictions, testing, quarantining and case tracing policies appear to have stemmed the virus as warm weather arrives in much of the country.
