A panel of experts from the World Health Organization has recommended further investigation into the leakage theory of the emerging coronavirus. The Scientific Advisory Group, which was formed by the World Health Organization in 2021 and includes 27 members from different countries, including Russia, China, India, Germany, the UK, and others, on the source of new pathogens (SAGO), indicates that the Leak Theory virus from the laboratory requires additional research.

The advisory group report indicated that epidemiological data and survey results suggest that the ancestors of the SARS-CoV-2 strain are of animal origin, and the closest genetically related viruses are a coronavirus beta mutant found in horseshoe bats in China in 2013 and Laos . As of 2020, however, no ancestor of the virus, no natural/intermediate host, and no cases of human transmission of the virus have been identified so far. Although the results of the preliminary investigation confirmed that the Wuhan seafood market played an important role in the spread of the pandemic, the source of the new coronavirus and the mechanism by which it entered the market is unknown. According to experts.
