Moving rapidly from one farm to the next, the virus has been devastating pig communities throughout China for more than a year, wiping out entire herds, driving pork prices up nearly 87 percent in a year and helping push the country's inflation rate to its highest levels since 1996.
The Chinese government has admitted that the swine deaths amount to an epidemic but contends that the situation is under control.
China says it is moving swiftly to stop the infections by quarantining and slaughtering the affected pigs. It says its researchers have developed an effective vaccine in record time for the likely cause -- blue ear pig disease, a reproductive and respiratory illness that is highly fatal in pigs but that so far does not seem to pose danger to humans. And it maintains that it has been "open and transparent" all along.
Some experts, both inside and outside China, are skeptical, citing the government's handling of the avian flu outbreak in 2004 and SARS in 2002 and 2003. While China's central government has made numerous improvements since then in how it deals with infectious disease control and informs the public, it has once again been slow to share scientific data and tissue samples with other countries.
As a result, there is worry that while China is lagging, the virus is quickly turning into a global problem. China does not export pork to the United States, but the virus has already been found in pigs in China's southern neighbors, Vietnam and Burma.
"We are concerned that with international traffic this particular virus could enter other continents -- Europe or Africa or the Americas," said Juan Lubroth, head of infectious diseases for the United Nations Food and Agriculture Organization, based in Rome.
