Via the Centre for Health Protection: Stay on guard against Japanese encephalitis. Excerpt:
The Government today (June 30) urged the public to stay alert to the risk of Japanese encephalitis (JE) and to take proper anti-mosquito measures.
Following a report of a JE case in Yuen Long in mid-June, the Food and Environmental Hygiene Department has been conducting JE vector surveys in the district and collected a total of seven batches of specimens of Culex tritaeniorhynchus for testing for the JE virus by the Department of Health (DH). Laboratory test results just confirmed that the JE virus was found in a batch of specimens of adult Culex tritaeniorhynchus collected in Mong Tseng Wai, Lau Fau Shan, Yuen Long, on June 26. The rest of the specimens did not carry the virus.
"Positive results from time to time are not unexpected as JE is endemic among local pigs. Mosquitoes may acquire the virus from wading birds and pigs, which are known hosts of the virus," the spokesman said.
Various government departments have strengthened inspections and mounted special operations in the vicinity, including larviciding and fogging to clean up the environment and remove mosquito breeding places, as well as related publicity and education efforts.
"The anti-mosquito actions and monitoring of JE vectors will continue," the spokesman said.
