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.
Seven years of surveillance and research revealed the complex history of the H1N1 virus that leapt from pigs to humans and sparked the global swine flu outbreak.
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.
Costly virus hunts are ineffective in protecting public health and have unfairly harmed the historically excellent safety record of bats as beneficial neighbors.
