Tag #H1N2

What factors contribute to the increasing frequency of H1N2 1C spillover events from pigs to humans?

The H1N2 1C virus's ability to bind to human airway receptors, replicate efficiently in human cells, and remain stable in airborne droplets significantly increases its transmissibility. This, coupled with low pre-existing immunity in the population (only about one-third of U.S. adults show detectable neutralizing antibodies), elevates its pandemic risk.
