In this video, Dr. Tommy Lam from the University of Hong Kong discusses the origins of the coronavirus. He explains that the virus likely emerged from animal populations, with bats being the most probable source. However, an intermediary host, such as a pangolin, may have facilitated the transmission from bats to humans. Dr. Lam also addresses conspiracy theories about the virus being man-made, stating that there is no evidence to support this claim. The exact cause of COVID-19 is still unknown, and understanding its origins is crucial for preventing future pandemics.
