During the pandemic, one of my go-to sources for context was science journalist Jon Cohen. Cohen is a long-time infectious disease reporter and a senior correspondent for Science magazine. He has written more than 100 deeply reported stories about all aspects of SARS-CoV-2, the virus that causes COVID-19, including how the virus impacts the body’s immune system and the global race to access vaccines.
Now that the acute phase of the pandemic is over, the story of where SARS-CoV-2 came from is gaining more prominence. Did it come from an animal? Or from a research lab? The answer remains elusive, though the greater share of evidence points to an animal.
