[T]he number one route of pathogen introduction to North America is … via military personnel. Military personnel who have been posted to various hot and chaotic climes do not undergo any medical screening if they don’t complain of sickness prior to returning home. Typhoid fever and hepatitis are regularly brought into the US by soldiers who return from being stationed in Afghanistan and Iraq.So it’s the heroes who are putting us at risk?
Tourists, it seems, are pathogen introduction route number two.
Illegal immigrants come in after ill winds.
