вЂњWe know now that this virus has a very unique feature, called the furin cleavage site that makes it the pandemic pathogen it is. On whether the virus was modified in the lab before a leak, Chan said: вЂњWe have heard from many top virologists that a genetically engineered origin of this virus is reasonable.and this includes virologists who themselves have made modifications to the first SARS virus. It might be five years from now, it might be 50 years from now, but we live in an era where there's so much data being collected and stored.we just need a credible, systematic investigation,вЂќ she said. вЂњRight now it's not safe for people who know about the origin of this pandemic to come forward. On the question of her level of confidence that the world would eventually be able to establish the true origins of COVID-19, Chan said it was simply a matter of time. There is no evidence pointing to a natural animal origin of the virus at that market,вЂќ she noted.

вЂњWe all agree that there was a critical event at the Huanan Seafood Market, that was a superspreader event caused by humans. A Canadian molecular biologist on Wednesday told cross-party members of Parliament (MPs) on the House of Commons Science and Technology Committee that a leak from a laboratory in Wuhan region of China is now the вЂњmore likelyвЂќ origin of the COVID-19 global pandemic.Дr Alina Chan, specialising in gene therapy and cell engineering and co-author of вЂViral: The Search for the Origin of COVID-19', told the Parliament panel's evidence session on scientific research that the pandemic was being caused by the unique feature of the coronavirus called вЂњfurin cleavage siteвЂќ, which has been linked to the Wuhan Institute of Virology.ДЄsked by the panel about the probability of a lab leak as the origin of the pandemic, Chan said a вЂњlab origin is more likely than natural origin at this pointвЂќ.
