The 2016 Summer Olympics takes place during the month of August in Rio de Janeiro. Apart from the focus on the athletes’ performance, the world is particularly concerned with the impacts on the spread of the Zika virus. Although August is not a mosquito season in Rio, numerous precautionary measures are taken by the Brazil government to prevent transmission of the virus among athletes and tourists.
The map shows the updated epidemic status of Zika in 2016 on the eve of Rio Olympics (5 August), highlighting the situations in countries of Central and South America and at state-level in Brazil. Cumulatively Brazil has reported 66,180 confirmed cases. Columbia and several countries of Central America also have more than 3,000 cases identified. Within Brazil, Bahia and Rio de Janeiro are the most seriously affected places in term of the cumulative number reported. Both have identified more than 40,000 suspected and confirmed cases. Expressing as an incidence by population, Mato Grosso gave the highest rate of around 9,000 cases per million population. The impacts of the Olympics on the Zika epidemic, if any, would unfold in the months to come.

二零一六年夏季奧林匹克運動會在八月於里約熱內盧舉行。矚目的除了運動員的表現外，各界都關注奧運會對寨卡病毒的傳播會有甚麼影響。雖然八月並不是里約熱內盧的蚊季，但巴西政府積極防蚊，嚴防病毒傳播。
地圖顯示截至奧運會開幕前夕 (8月5日)，寨卡病毒於中南美洲國家及巴西各州分於2016年的疫情。其中，單以巴西已經有66,180宗累積確診個案。哥倫比亞及中美洲多國亦錄得超過3,000宗個案。而巴西各州分中，巴伊亞州及里約熱內盧州均錄得超過40,000宗懷疑及確診個案成為最嚴重受創州分 。若以人口比例計，馬托格羅索州則以每百萬人9,000個案遠超其他州分。奧運會會否影響寨卡疫情，讓我們拭目以待。

Zika Virus 寨卡病毒
What is Zika virus? 什麼是寨卡病毒
- Zika virus is the cause of a mosquito-borne infectious disease. Common symptoms of Zika virus disease include fever, rash, joint pain and conjunctivitis. The illness is usually mild and seldom requires hospitalization. In May 2015, multiple birth defects of new-born babies, including microcephaly, and Guillain-Barré syndrome were reported in Brazil. It is highly suspected that Zika virus is the causative agent of such outbreaks. It is therefore a new concern for pregnant women who may be exposed to the virus.
- 寨卡病毒感染是一種以蚊傳播的傳染病。感染後常見病徵包括發燒、皮疹、肌肉或關節疼痛及結膜炎。寨卡病毒引發的病徵一般輕微，只有少數病者需要留院治療。於2015年5月，巴西出現多宗初生嬰兒畸形包括俗稱『小頭症』及吉巴氏綜合症，同期爆發的寨卡病毒極大可能為其致病原因。寨卡病毒為疫症地區孕婦帶來新的憂慮。
How does it spread? 如何傳播?
- Zika virus is spread through the bite of mosquitoes from the Aedes genus, primarily Aedes aegypti. The common Aedes albopictus in Hong Kong and Macao could also be the vector for transmitting Zika virus. Recent research also suggests that the virus could be transmitted through sexual contact.
- 寨卡病毒主要是經被帶有病毒的埃及伊蚊叮後而傳播的傳染病，香港及澳門常見的白紋伊蚊亦可作為其蚊媒。近期研究亦指出病毒有機會經性接觸傳播。
Vaccine? Prevention? 如何預防?
- Currently there is no vaccine to protect from Zika virus. The best measure is to minimise the breeding grounds of the Aedes mosquitoes by for example sealing up puddles of stagnant water, and avoiding mosquito bites, for example through the use of insect repellent and mosquito nets.
- 目前仍未有有效防止寨卡病毒感染的疫苗。預防措施的重點首是減少伊蚊繁殖的地方，包括清除積水防止蚊子滋生，以及避免被蚊子叮咬，例如使用驅蚊劑和蚊帳。
