Animal spillover? Lab leak? What the science says about the origins of COVID-19

The debate over whether COVID-19 originated from a lab leak or animal spillover has gained renewed attention with the release of Dr. Anthony Fauci's pandemic diaries. Scientists remain divided, with some supporting the theory that the virus naturally jumped from animals to humans, while others suggest a lab accident in Wuhan. This controversy matters because understanding the origins could shape future pandemic preparedness and response strategies, influencing everything from global health policies to international relations. The release of Fauci's documents adds fuel to this contentious discussion, prompting a deeper look at the evidence and its implications.
