The three things you need to know:
- the more long-distance travel there is, the more aggressive a pathogen can be and not go extinct by killing all the hosts it can reach what with being able to reach more hosts
- if you keep adding long-distance travel, there's an abrupt transition between extinction being unlikely and extinction being nigh-certain for the host population. We know this point exists but not how to identify it in the real world.
- if you think this doesn't apply to extractive economic behaviour as well as diseases, you need to contemplate the concept of "model" a little more.
Prolonged upper respiratory tract viral DNA shedding after skin lesion resolution challenged current infection prevention and control guidance.
That is, the traditional-with-pox viruses guidance that after the lesions scab over and the scabs fall off you're not contagious anymore? With this pox virus, that's wrong. Effective treatment involves at least a month of strict isolation of the patient, and we purely do not have the capacity to do that for very many people.
