The origin of the pandemic
At a recent press briefing, the World Health Organization team investigating the origin of the covid-19 pandemic dismissed the possibility that the virus had accidentally leaked from a laboratory (Nature doi:10.1038/d41586-021-00375-7). But some commentators find the circumstantial evidence hard to ignore. The Wuhan Institute of Virology is only 10 miles from the site of the initial outbreak and is known to research wild coronaviruses. In contrast, the natural coronavirus variants that most closely resemble SARS-CoV-2 come from a region in south west China more than 900 miles away (https://undark.org/2021/03/18/utterly-plausible-lab-leak-hypothesis/).
