North-American Influenza - USDA vet tells Senate: New virus not found in U.S. swine

30-Apr-2009
The H1N1 virus that has triggered fears of a global human flu pandemic has not been found in U.S. swine and so far has not "been shown to affect swine," U.S. Department of Agriculture chief veterinarian Dr. John Clifford testified yesterday during a Senate hearing. Naming the virus "swine flu" -- a name, Clifford allowed, that was apt to stick -- has caused unnecessary alarm with U.S. trade partners and dismay in the animal agriculture industry.

North-American Influenza - FAO acts over H1N1 human crisis

30-Apr-2009
The FAO-OIE Crisis Management Centre – Animal Health is mobilizing a team of experts to assist government efforts to protect the pig sector from the novel H1N1 virus by confirming there is no direct link to pigs, increasing animal disease surveillance and maintaining response readiness should the new virus become introduced into the pig population.

North-American Influenza - OIE position on safety of international trade of pigs and products of pig origin

29-Apr-2009
Because the current A/H1N1 related human health event has been described as swine influenza, the World Organisation for Animal Health (OIE) wishes to further clarify the facts from the animal health perspective, particularly in relation to international trade of pigs and of products of pig origin. The OIE also points out that it will continue to respond to new, incoming information as the situation evolves.

North-American human influenza

It is produced by a virus with genetic material from porcine, human and avian viruses which has shown the ability unusually for such a virus to transmit from human to human. The virus appears to have 2 of 8 gene segments that derive from eurasian swine viruses. The NA and matrix genes of the new virus have not been seen in humans or pigs before.

Swine influenza: epidemiology and emergence of new viruses

The first swine influenza viruses were all H1N1 and were for about 60 years in North America. In the middle 1980’s, there appeared in European pigs H3N2 viruses that were derived originally from humans and had adapted to pigs and were therefore known as human-like H3N2 viruses. These viruses have since appeared in other parts of the world most notably as H3N2 in the USA in 1998. These viruses however contained bits of human, avian and swine viruses and were therefore called triple re-assortants.

North-American Influenza - A/H1N1 influenza like human illness in Mexico and the USA: OIE statement

28-Apr-2009
Any current information in influenza like animal disease in Mexico or the USA could support a link between human cases and possible animal cases including swine. The virus has not been isolated in animals to date. Therefore, it is not justified to name this disease swine influenza. In the past, many human influenza epidemics with animal origin have been named using their geographic name, eg Spanish influenza or Asiatic influenza, thus it would be logical to call this disease “North-American influenza”.

North-American Influenza - WHO raises pandemic alert level

28-Apr-2009
The Emergency Committee, established in compliance with the International Health Regulations (2005), held its second meeting on 27 April 2009. The WHO Director-General has raised the level of influenza pandemic alert from the current phase 3 to phase 4.
