Via the Centre for Health Protection: CHP investigates imported case of Japanese encephalitis. Excerpt:
The Centre for Health Protection (CHP) of the Department of Health (DH) is today (August 24) investigating an imported case of Japanese encephalitis (JE) affecting a man aged 61 and urged the public to take precautions against mosquito-transmitted diseases.
The patient, with good past health, travelled to Yingcheng, Hubei from July 30 to August 13. He developed fever, headache, arthralgia and vomiting since August 13, and consulted a private doctor on August 14. As his symptoms persisted, he attended the Accident and Emergency Department of Princess Margaret Hospital on August 16. He was admitted on the same day for further management and was found to be confused and disorientated upon admission. He has all along been in a stable condition.
His cerebrospinal fluid tested positive for immunoglobulin M (IgM) antibodies against JE upon testing by the CHP's Public Health Laboratory Services Branch.
Epidemiological investigations are ongoing. According to the patient's information, his travel collaterals have remained asymptomatic so far. He could recall mosquito bites in the Mainland during the incubation period.
To date, two JE cases (one under investigation and one imported) have been reported to the CHP this year. Two (one local, one unclassified) and five (three local, two imported) were filed in 2015 and 2014 respectively.
