日本腦炎 Japanese B encephalitis

Hong Kong Hiking Web: 戶外大夫專欄 Outdoor Doctor Forum: 日本腦炎 Japanese B encephalitis
   By Outdoor Doctor (Doctor) on Thursday, June 10, 2004 - 8:38 pm:  Edit

A young woman died of Japanese B encephalitis recently in Hong Kong. The causative agent is Japanese B encephalitis virus. It is transmitted by a species of mosquito (namely Culex). Mosquito bites infected pig or bird. Afterwards, it can transmit the virus to human.

This disease was rarely seen in Hong Kong previously.
The death of the woman should raise alert to all hikers in Hong Kong. Most the people infected by the virus will get mild symptom or no symptom. However, it can definitely cause an extremely serious form of encephalitis 腦炎 and lead to death.

Being an outdoorer, you should prevent mosquito bite always. Suggestions: 1) wear long-sleeve shirts and trousers, 2) apply insect repellent (e.g. those containing DEET), 3) avoid going to places with a lot of mosquitoes.

If you got fever/headache/confusion a few days after being bitten by mosquito, you'd better see a doctor and have a proper examination. The disease can progress VERY RAPIDLY and can kill oneself.

There is no proven drug to treat this viral disease.

If you encounter such illness or know that your hiking friend having an encephalitis (and was admitted to hospital recently), please tell us (especially the wild place they have gone).

The species of mosquito (Culex) transmitting Japanese encephalitis is not the same as those common mosquito (白紋伊蚊) transmitting Dengue Fever. Many of us can recognize the 白紋伊蚊 from the black and white strip on the legs.

Does anybody know how to recognize the Culex mosquite?

There is no specific treatment for Japanese encephalitis (i.e. no drug is available to kill that virus). Some patients may just have a mild illness after having this infection. One out of 300 patients can have encephalitis which is a severe illness. Doctors used drugs, fluids and sometimes mechanical ventilation to support the life of the patient. Serious encephalitis can cause permanent damage to the brain.
