Veterinarians play down disease threat

Although some have blamed the current epidemic on the unsanitary conditions of Sichuan's small-scale pig farms combined with hot temperatures, Yao said experts had yet to determine what specifically triggered the outbreak.

The bacteria is endemic in swine, but experts need to know under what conditions the disease will break out, given that not all pigs on a single farm will come down with the disease, Yao said.

"I hope more money and manpower will be pooled to study the infection and find out what other animals may carry and transmit the bacteria," he said.

The Ministry of Health issued a national guideline yesterday explaining the symptoms of the disease, and how to treat patients and prevent and control the epidemic.
