China organizes national Japanese encephalitis workshop

28–29 September 2011 - Chengdu, China

The China Centers for Disease Control (China CDC) organized a "National Workshop on Japanese Encephalitis Surveillance and Laboratory Testing" from 28 to 29 September, 2011 in Chengdu, China. More than 65 participants from China CDC, selected provincial CDCs, vaccine manufacturers and the World Health Organization attended. Officials from China CDC presented summaries of national Japanese encephalitis (JE) surveillance data and recent JE related research activities followed by presentations by nine provincial CDCs on JE incidence, disease burden and vaccination data. Most provincial laboratories conduct vector (mosquito) surveillance, pig serosurveillance and healthy children serosurvey as well as JE/Acute Encephalitis Syndrome surveillance. The first JE vaccine came into use in China in the 1970s, and the number of reported JE cases has gradually declined since then, but China still accounts for an estimated half of global JE cases. JE vaccine was added to the national EPI schedule in 2008 to accelerate JE control. Experience presented from the provinces in this meeting suggests that routine JE vaccine use along with catch-up campaigns has had an impact. The China CDC JE laboratory is a WHO Regional Reference Laboratory and provides training and quality assurance for a network of provincial and lower-level laboratories, which conduct primary testing for JE. In 2011, China's Ministry of Health will designate 10 subnational JE laboratories in China, which will also collaborate with the Western Pacific Regional Office.
