Australian scientist defends Wuhan lab's operation By MAY ZHOU in Houston | China Daily Global | Updated: 2021-06-29 11:13 [Photo/Agencies] Virologist Danielle Anderson, the last and only foreign scientist who was in the Wuhan Institute of Virology's BSL-4 Lab until November 2019, a couple of months before the COVID-19 outbreak, spoke out for the first time since the pandemic and said she believes the novel coronavirus "was a natural acquired infection at some point somewhere". In what appeared to be an exclusive interview with Bloomberg, Anderson talked about her experience in the Wuhan Institute of Virology and said that half-truths and distorted information have obscured an accurate accounting of the lab's functions and activities.
