The Hunt for a Pandemic’s Origins
Martha Nelson | Jan 4, 2022
Dozens of researchers, including myself, worked for years to uncover that swine flu had leapt to humans from a pig in Mexico in 2009. We learned a lot about influenza evolution, pig farming, and outbreak risk along the way.

Q&A: New Tool Ranks Viruses by Their Risk of Jumping to Humans
Jef Akst | Apr 9, 2021
Researchers involved in a long-term project to identify viruses of concern have now assessed the risk factors that could help forecast which pathogens are the most likely to spillover from wildlife to people.
Opinion: Disease Prediction by Bat Virus Surveys Is a Waste
