HANOI, May 27 (Xinhua) --

Porcine Reproductive and Respiratory Syndrome (PRRS), known as "blue ear" disease, has hit 270,000 pigsin Vietnam, or one percent of the country's pig population, since late March, local newspaper Vietnam Economic Times reported Tuesday.

Northern Thanh Hoa province has suffered the biggest loss with nearly 200,000 affected pigs, accounting for nearly 15 percent of the province's pig population, the paper quoted Nguyen Thanh Son, vice director of the country's Department of Animal Health, as saying.

Now, PRRS is hitting 10 Vietnamese provinces, including Thanh Hoa, Thai Binh, Thai Nguyen, Nam Dinh and Ninh Binh in the northern region, and Ha Tinh, Nghe An, Lam Dong and Thua Thien Huein the central region, and Vinh Long in the southern one, according to the department.

Two die in Vietnam from pig virus, bird flu returns

Monday, July 23, 2007


HANOI (Reuters) - Two people have died in northern Vietnam from a virus that has killed thousands of pigs in recent weeks while bird flu has returned to the central region, killing hundreds of ducks, government and media reports said.

Twenty two people, most from northern areas, have been taken to a Hanoi hospital so far this year after they fell sick from the Porcine Reproductive and Respiratory Syndrome (PRRS) virus, the Vietnam News Agency said on Monday.

Two of the infected had died, it said without giving more details.

On July 14, Agriculture Minister Cao Duc Phat said more than 16,000 pigs had been infected by the virus

Virus Spreading Alarm and Pig Disease in China

A highly infectious swine virus is sweeping China's pig population. believed to cause an unusually deadly form of an infection known as blue-ear pig disease
"They haven't really explained what this virus is," says Federico A.
Zuckermann, a professor of immunology at the University of Illinois College of Veterinary Medicine. "This is like SARS. They haven't sent samples to any international body.

Health experts say China has declined to send tissue samples to testing labs outside the country for independent verification by a lab affiliated with the World Organization for Animal Health in Paris.

International health experts are already calling this one of the worst disease outbreaks ever to hit Asia's livestock industry

A similar virus has already been detected in neighboring Vietnam and Myanmar
other experts say they are not even certain that the blue-ear virus is the one that is spreading.

Scientists who track blue-ear pig disease are puzzled because the disease is generally not so deadly.

"This virus generally makes them ill but on its own it doesn't cause a lot of deaths," said Steven McOrist, a professor of pig medicines at the University of Nottingham in England. "The evidence they put up so far is not conclusive."
"This is more severe than we've seen elsewhere," said Derek Armstrong, a senior veterinary scientist at the Meat and Livestock Commission in Britain. "It may be a co-infection of pigs with other things."

The United Nations Food and Agriculture Organization is now pressing China to share its research and tissue samples.

Government scientists themselves said that last year the virus affected two millions pigs and killed 400,000. Here in Sichuan province, home to some 55 million pigs and one of the world's most densely populated pig breeding areas, there is devastation.

Many experts, meanwhile, worry that China, which the F.A.O. says is the fourth-largest exporter of live and slaughtered hogs, could already be exporting the disease.

"This is already considered to be a threat to the global industry," said Trevor Drew, head of virology at the Veterinary Laboratories Agency in Weybridge, in southeast England. "It would be na?ve to think we could contain this virus."

Porcine Respiratory Disease Complex

Lawrence D. Firkins, D.V.M., M.S.
01/01/1998

Porcine Respiratory Disease Complex (PRDC) is the result of a combination of multiple infectious agents,environmental stressors and production system challenges. Successful intervention requires accurate diagnosis

common respiratory agents in PRDC are PRRS virus,swine influenza virus
A swine influenza control program will be needed on many farms with a history of PRDC. Good results have been obtained through immunization of the sow herd. When stabilizing a breeding herd, initially two doses must be given three weeks apart.

Porcine Respiratory Disease Complex remains a challenge to producers. It is now clear that PRRS is generally involved. Influenza can play a role with PRRS or independent of any other viruses. In order to effectively deal with PRDC, the contributing pathogens must first be identified.

Two die in Vietnam from pig virus, bird flu returns

These deaths may be due to another swine pathogen recently circulated in southern China (Streptococcus Suis). A number cases of severe septic shock happened at Hong Kong, although in a sporadic manner.

Re: _|PRSS IN VIETNAM: AGAIN|_

Yes, it seems that now especially since the disease is so prevalent in Vietnam, we should be seeing a more comprehensive laboratory analysis of these cases. It seems that this is being made as a clinical diagnosis... blue-ear disease...

"blue ear" disease, has hit 270,000 pigs in Vietnam, or one percent
of the country's pig population, between late March 2008 and late May 2008

projection this for China would give 5 million sick pigs,
40% dying(AFAIR), just for 2 months !
