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.
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.
U.S. commodity markets retreated Monday in part on fears related to the outbreak of swine flu, potential reduced pork consumption and the banning of pork imports from the United States by Russia, China and other countries, although there have been no reports of the virus in U.S. swine.
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.
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.
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”.
German pig futures prices fell by around 3.5 percent on Monday because of fears that bad publicity about swine fever will cut pork consumption, traders said.
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.
The Russian government has suspended imports of all meat from Mexico as well as Texas, California and Kansas shipped after April 21 on fears of the spread of swine flu. In addition, China has banned pork imports from Mexico and the U.S. states of Texas, Kansas and California.
As of 26 April 2009, the United States Government has reported 20 laboratory confirmed human cases of swine influenza A/H1N1 and the Government of Mexico has reported 18 laboratory confirmed cases of swine influenza A/H1N1.
The Public Health Agency of Canada’s National Microbiology Lab in Winnipeg has confirmed four cases of A, H1N1 swine flu from Nova Scotia. The British Columbia Centre for Disease Control identified two additional cases from British Columbia. All six cases are same strain of human swine influenza that has been found in the U.S. and Mexico. These first cases were detected as a result of the increased surveillance the federal government initiated with the provinces and territories and health professionals given concerns over the spread of swine flu in Mexico and the United States.
The National Pork Producers Council and the National Pork Board are urging all pork producers to take steps to prevent their pigs from contracting swine influenza.
The Australian Veterinary Association says the international swine flu outbreaks not a threat to Australian pigs and that eating pork poses no human health risk.
The AVA is not concerned about an outbreak among pigs here in Australia.
Considering the current situation we are reproducing an article by Tom Alexander previously published by 3tres3.com on 30/dec/2005.
A key factor in the epidemiology of influenza is the ability of the virus to mutate or, when cells are infected by two different strains, to recombine to produce new viruses. Either of these genetic changes results in the repeated appearance of new strains with different immunogenic structures and/or virulence, including their ability to infect different hosts.
