Undiagnosed (?) Pig Disease
Rages In China

From Patricia Doyle, PhD
Hello Jeff - Please note that Promed is still calling the pig outbreak, undiagnosed. China calls it everything from Strep Suis to High Fever Pig Disease to, the new one, Blue Ear but we still do not have a definite pathogen or disease name.
Classical Swine Fever, African Swine Fever, Blue Ear, Pig High Fever Disease? Whatever it is, it is still ravaging Chinese pigs.

According to Xinhua News Agency, a spokesperson for the News Office of the Ministry of Agriculture said yesterday [17 Jun 2007] that at the start of June [2007], Chongqing, Hunan, Guangxi, Guizhou, and Shaanxi provinces had outbreaks of highly pathogenic pig blue ear disease.
Because locales made preparations extremely early this summer, improving preventative dynamics and putting in place comprehensive preventative measures, highly pathogenic pig blue ear disease is somewhat milder than during the same period last year [2006], with sporadic occurrence [only]. There has not been widespread occurrence.
The Ministry of Agriculture has transferred more than 20 million milliliters of pig blue ear disease vaccine and the Ministry of Finance is releasing 285 million CNY [USD 37.4 million] in supplemental vaccine funds. Vaccination work is now being carried out in key locales. All regions are intensifying outbreak reporting systems, in accordance with the Ministry of Agriculture's outbreak monitoring schemes and reporting system requirements. When suspected outbreaks are discovered, quick verification, prompt diagnosis, and prompt reporting via the animal disease surveillance network [is done].

In a recent media-derived information (see ProMED-mail 20070612.1913), the following provinces were mentioned to have been affected by the so-called "swine high fever disease" (SHFD) -- in which porcine reproductive and respiratory syndrome (PRRS, also called blue ear disease) seems to play a role -- since its 1st appearance in mid 2006: Hunan, Hubei, Jiangxi, Henan, Hebei, Yunnan, some areas of Guandgong, some areas of Guangxi, the western part of Shandong, Zhejiang, Fujian, Jiangsu, Anhui, Beijing/Tianjin/Tangshan, Liaoning, Jilin, and Inner Mongolia. Other reports mention different data.

The flood of data, originating from various (official, semi-official, unofficial, central, provincial, and foreign) sources, with contradictory pieces of information on SHFD, its etiology and distribution, could be put on hold if/when detailed, 1st hand, authoritative results of laboratory investigations from each affected province become available, pertaining -- in addition to PRRS (blue ear disease) -- to the entire range of potential causal agents (including classical swine fever/CSF, African swine fever/ASF, avian influenza, and foot-and-mouth disease/FMD) and preferably officially submitted to the OIE. It would be reassuring if samples were to be submitted for confirmation to OIE's ASF (World Organization for Animal Health, African swine fever) reference laboratory(ies). - Mod.AS
