Menangle virus infection is a recently emerged, zoonotic disease of swine, currently limited to one outbreak in Menangle, New South Wales, Australia. Menangle virus appears to be maintained asymptomatically in fruit bat (flying fox) populations, but it can emerge to become established in some swine herds. Sows infected with Menangle virus have a reduced farrowing rate and give birth to smaller litters with fewer live piglets. Affected litters have an increased number of mummified or stillborn piglets, some with congenital defects of the skeletal and neurological systems. This virus is also zoonotic: during the only known outbreak, two people who were in close contact with infected pigs developed a severe but selflimited influenza-like disease.
