Rapid and reliable methods for detection of these organisms are needed to prevent further dissemination.

A systematic review of the global occurrence of zoonotic TB, suggesting a worldwide low incidence of the disease, even in high-risk, low-income countries.

Epidemic fade-out occurred as susceptible hosts were depleted and vector-suitable environmental conditions declined.

Short-term travelers often visit (sub)tropical regions where influenza viruses continuously circulate and after contracting the disease they could become vectors that further spread the virus worldwide.

Control efforts could be targeted according to dry season incidence and proximity to known epidemic hotspots.

Different influenza viruses circulate simultaneously among pig populations throughout the year.

This lineage is more closely related to human-associated than to classical animal-associated M. tuberculosis complex strains.
