Ecologic and evolutionary features of multihost pathogens determine the likelihood of emerging infectious diseases.

Integrating virology, ecology, and other disciplines enhances prediction of new emerging zoonoses.

Emerging and reemerging species of human pathogens are associated with a broad range of nonhuman hosts.

Epidemiologic and genetic data show that person-to-person spread likely took place during the prodromal phase or shortly after it ended.

Genotype 5 lyssaviruses are endemic in the Netherlands, and can cause fatal infections in humans.

Contact with food animals was associated with SARS-CoV infection in the People’s Republic of China.

This area has the highest prevalences of both forms of this disease in the world.

Pigs may be reservoirs for human noroviruses, and porcine/human genogroup II recombinants could emerge.

Airborne transmission may have resulted in an outbreak of SARS in Hong Kong.

The PanAsia strain is spreading explosively in Asia and extending to parts of Africa and Europe.

DNA in porpoises suggests an emerging infectious disease in marine mammals.

Food animals are likely the primary reservoir of resistant S. Typhimurium.

Etiologic subtype IC of virus persists, 5 years after the major 1995 epidemic.

This first report of intergenogroup recombination for any calicivirus highlights a possible route of zoonoses.
