"The medical, the nutritional and the food research industries all are keenly interested in the health benefits of phytochemicals in all sorts of fruits and vegetables," said Myers. "We are happy to find out we can accomplish this in...... outbreaks in people." However, the researchers say that much more work needs to be done to understand the multiple variables driving the emergence of infectious diseases from wildlife to human populations.
