The first reports were not from China. They were from countries south of China after H5N1 Bird Flu spread to those countries. Here is the first report from VietNam in 2004. Note the quick communist government DENIAL!

HANOI - A deadly strain of bird flu has been detected in initial tests of several Vietnamese pigs, the Food and Agriculture Organization said Friday, but a Vietnamese government official said they were unaware of any such finding.

"The H5N1 virus was in the nasal cavities of the pigs," said Anton Rychener, Vietnam representative of the U.N. agency. He added that blood tests on the pigs had been sent to Hong Kong and results were not yet returned. The pigs had not fallen ill with the virus that has killed at least 18 humans.

Indonesian pigs have avian flu virus; bird cases double in China

May 27, 2005 (CIDRAP News) – Avian influenza could be infecting up to half of the pig population in some areas of Indonesia, but without causing symptoms, Nature magazine reported in this week's edition.

Meanwhile, Chinese officials said a flu outbreak among wild birds is twice as large as previously reported, but they denied reports of human cases.

In Indonesia, Chairul Nidom, a virologist at Airlangga University's tropical disease center in Surabaya, Java, was conducting independent research earlier this year. He tested the blood of 10 apparently healthy pigs housed near poultry farms in western Java where avian flu had broken out, Nature reported. Five of the pig samples contained the H5N1 virus.

The Indonesian government has since found similar results in the same region, Nature reported. Additional tests of 150 pigs outside the area were negative. However, the story said, lack of funding for surveillance and testing is a concern to Nidom, who said he has samples from 90 more pigs from Banten, but he can't afford to test them or to broaden his investigation.

"I think pigs pose a much greater threat of spreading the disease to humans than poultry," Nidom told Nature. Pigs are often described as a mixing vessel in which human and avian flu viruses can swap genetic information, which could lead to a hybrid virus with the ability to spread easily among people.

The Indonesian government sent a report to the World Organization for Animal Health (OIE) on May 23 that describes three surveys involving "purposive and pooled sampling" of pigs, with a total 187 samples.

The first survey, Nidom's Feb 23 study on one farm, yielded 5 positives out of 10 samples tested for H5N1. The second, on Apr 14 in another village, involved 10 nasal swabs from 31 pigs and produced positives in 6 of the 10…..
