One official dismissed the lab leak theory as a rumor that ran counter to common sense.

A senior Chinese health official said on Thursday he was shocked by the World Health Organization’s plan for the second phase of a study into the origins of COVID-19.

Deputy Minister of the National Health Commission Zeng Yixin dismissed the theory of laboratory leaks as a rumor going against common sense.

The WHO chief admitted last week that it was premature to rule out a potential link between the pandemic and a coronavirus leak from a Chinese laboratory.

Mr. Zeng called the theory a rumor that flies in the face of science.
