Several lab-leak theories have been circulating which propose that COVID-19 may have accidentally escaped from a lab in Wuhan, China. Supporters of this theory point to the Wuhan Institute of Virology’s work on bat coronaviruses, some reportedly similar to COVID-19.
However, it’s important to stress that all conclusions, for now, are theories and under investigation and review. Scientific consensus has not been reached on the lab-leak theory or the zoonotic transmission theory. Scientists and investigators are working to gather more data for a clearer picture. So, I would advise checking the latest and most reliable health or news websites for the most recent updates.
