Swine fever
African swine fever virus (ASFV) is a large, double-stranded DNA virus in the Asfarviridae family. It is the causative agent of African swine fever (ASF). The virus causes a hemorrhagic fever with high mortality rates in domestic pigs; some isolates can cause death of animals as quickly as a week after infection. It persistently infects its natural hosts, warthogs, bushpigs, and soft ticks of the genus Ornithodoros, which likely act as a vector, with no disease signs. It does not cause disease in humans. ASFV is endemic to sub-Saharan Africa and exists in the wild through a cycle of infection between ticks and wild pigs, bushpigs, and warthogs. The disease was first described after European settlers brought pigs into areas endemic with ASFV, and as such, is an example of an emerging infectious disease.
ASFV replicates in the cytoplasm of infected cells. It is the only virus with a double-stranded DNA genome known to be transmitted by arthropods.
MERIAL launches new White Book on Classical Swine fever at recent Asian Pig Veterinary Society Congress, Manila, Philippines.
During the 2nd Congress of the Asian Pig Veterinary Society Congress (19 & 20 September 2005) held at the Edsa Shangri-la Hotel, Manila, a Corporate Symposium was organised by MERIAL on classical swine fever (better known in the Philippines as hog cholera).

USDA's Animal and Plant Health Inspection Service is amending its regulations by adding Chile to the list of regions considered free of classical swine fever (CSF). Chile also is added to a list of CSF-free regions that must meet certain certification requirements.
This amendment will allow Chile to export live swine, swine semen, pork and pork products to the United States. The certification requirements for origin and handling are intended to ensure that exports of these commodities do not...
