Characteristics

Coronaviruses

Influenza

Paramyxoviruses (henipaviruses)

Animal reservoirs

Huge diversity in insectivorous bats and fruit-eating bats. Horseshoe bats (genus Rhinolophus) in Southeast Asia harbor SARS-like coronaviruses.

Water birds, poultry, and domestic pigs. Some outbreaks in dogs and horses.

Some family members abundant in fruit bats.
