Nipah virus (NiV) is an emerging zoonotic virus that can be transmitted to humans from animals (both wild and domestic). Fruit bats of the Pteropodidae family are the natural hosts of Nipah virus. NiV infection can be asymptomatic or mild (subclinical), but it also causes acute respiratory illness and fatal encephalitis.

Swine influenza is a respiratory disease of pigs caused by type A influenza viruses that regularly cause outbreaks of influenza in pigs. Influenza viruses that commonly circulate in swine are called “swine influenza viruses” or “swine flu viruses.” Like human influenza viruses, there are different subtypes and strains of swine influenza viruses.
