Encephalitis suspect in Yuen Long
Sylvia Hui
A New Territories man is suspected of having contracted Japanese encephalitis, the Centre for Health Protection said.
The 45-year-old lives in Palm Springs, Yuen Long, and lab tests are being conducted to confirm the diagnosis. If confirmed, it would be the second local case of Japanese encephalitis this year.
Results of the laboratory tests are expected within a day.
The Food and Environmental Hygiene Department has carried out vector surveys and mosquito control measures near the patient's residence.
The man, a Hong Kong resident, became ill on June 8. He developed symptoms including fever, headache and drowsiness. He was admitted to the North District Hospital and was later transferred to the Pamela Youde Nethersole Eastern Hospital where he is in a critical condition.
The patient has not travelled outside Hong Kong in the past three months. The centre's medical staff have visited the patient's four household contacts and put them under medical surveillance.
They did not have any symptoms of the illness.
Relevant departments will take action in the event the case is confirmed.
``If proven, the case would prove that Japanese encephalitis is a very serious threat indeed,'' medical constituency legislator Lo Wing-lok said. ``It would mean that the disease has spread from west Kowloon to west of the New Territories, affecting a much larger area and population,'' he said. The dengue fever outbreak last year also originated from these two districts.
``These are the high-risk districts and the government must step up its pest control measures.''
Seven cases of the disease have been reported since 1992, and earlier this month an Indonesian domestic helper living in Kwai Chung died of the disease.
Japanese encephalitis is transmitted by Culicine mosquitoes that breed mainly in rural areas.
Mosquito levels in the territory have increased in recent months.
The overall mosquito index reading for last month was 31.6 per cent, a significant increase from April's 11.9 per cent. The index for the same period last year was just 17.1 per cent.
The mosquitoes breed in waterlogged fields and marshes.
Removing stagnant water helps prevent them from breeding.

As a resident in Palm Springs and a birdwatcher, I think I can share my views with you on this piece of news. If you can remember that there was a similar case of JE a few months ago who was a resident of Fairview Park, it's no surprise that it will happen again in the neighbourhood.
JE is endemic in our neighbouring countries. JE virus needs ampliflying hosts, commonly pigs and unfortunately our feathered friends, like herons, in its natural cycle. It is well known that these two elements are around this area, and so possibily is the virus too.
The first case in Lai Chi Kok is more alarming since there is no pig farm within 2km.
Vaccination on pigs and anti-mosquito measures together with public awareness are the only ways to prevent a major outbreak in human.
I think to avoid being bitten by a mosquito is always a wise thing to do (esp during dawn, dusk and night). Good luck and happy birding!

why the government has to accuse the birds for spreading JE in such a high profile? To cover up their failure in mosquitos preventive measure?
Or....provide an excuse of property developers to "clean up" lands near Mai Po/TBT, and build up a "well-managed" estate to prevent JE?

Well, there appears to be some difference among the reports from different newspapers. I believe the apparent "high profile accusation" may originate from some of the news reporters / editors rather than the government.

米埔白鷺曾驗出抗體
【東方日報專訊】漁農自然護理署證實，早前在米埔的白鷺身上驗出日本腦炎病毒抗體。先後有居民感染日本腦炎的元朗錦𥉐花園及加州花園毗鄰候鳥出沒的米埔自然保護區，而早前發現日本腦炎的九華徑新村附近根本沒有豬場，令病毒源頭指向野鳥。但管理米埔的世界自然（香港）基金會強調，豬隻才是主要的傳播媒介，該會一直有在米埔進行防蚊工作，市民做足防蚊措施，觀鳥仍是安全。
漁護署高級獸醫王啟熙昨表示，有定期抽驗野鳥的血清，早前曾發現一些白鷺帶有 日本腦炎抗體，顯示牠們曾受感染。
王啟熙稱，野鳥染病只為期三、四天，庫蚊必須在該數天內叮到牠們，才會感染病 毒再叮人傳播。
保護區稱觀鳥安全
米埔自然保護區經理楊路年昨強調，日本腦炎「唔關雀仔事」，眾多候鳥中只有白鷺才會感染日本腦炎，其他候鳥不受影響。他指，現時米埔只有一萬隻候鳥，較冬天時五至六萬隻為少。世界自然（香港）基金會一直在米埔進行如清除積水、在魚塘飼養食蚊魚及蝦等防蚊措施。他強調，市民接觸雀鳥不會感染日本腦炎，市民做足防蚊措施，觀鳥仍是安全。市民應採取的預防措施包括到戶外時，應穿長袖衫及長褲保護手腳，特別是足踝；亦應在外露的皮膚重複塗驅蚊劑，及避免逗留在茂密的草叢範圍。
宪生署宪生防護中心顧問醫生曾浩輝則稱，市民若感到自己屬受感染高危一族，應 暫時避免到郊外觀鳥，但相信市民做足預防措施，觀鳥還是安全。

明報 Mingpao 七成野鳥有日腦抗體
http://full.mingpaonews.com/20040626/gaa2r.htm
「【 明 報 專 訊 】 雀 鳥 是 日 本 腦 炎 病 毒 的 其 中 一 個 天 然 宿 主 ， 漁 護 署 過 去 監 察 野 鳥 ， 發 現 高 達 六 至 七 成 有 日 腦 抗 體 ， 顯 示 牠 們 曾 受 感 染 ， 而 受 感 染 的 雀 鳥 ， 主 要 是 白 鷺 （ egret ） 、 鷺 鳥 （ heron ） 及 烏 鴉 （ crow ） ， 漁 護 署 正 監 察 鳥 類 以 取 得 更 多 日 腦 資 料 。 」
AFCD's monitoring found Japanese encephalitis antibodies in up to 60 to 70% of wild birds, which means that they have been infected by the virus previously. The affected birds are mainly egrets, herons and crows.
