microcephaly
記事の中で気になった単語は"microcephaly"です。Oxford Dictionaries.comには"Abnormal smallness of the head, a congenital condition associated with incomplete brain development"と定義されております。先天的に頭が小さい状態で生まれる症状を指すようです。
ブラジルでは，このような小頭症で生まれる子どもが上昇しているとのことです。蚊を媒介として観戦するジカ熱と関連がある可能性が指摘されております。米国では妊婦はブラジルへの旅行を控えるように警告を出しました。（Ume）
Brazil Zika outbreak: More babies born with birth defects
New figures from Brazil show a further rise in the number of babies born with abnormally small heads to mothers infected with the Zika virus.
There have been 3,893 cases of microcephaly since October, when the authorities first noticed a surge, up from 3,500 in last week's report.
Zika is transmitted by the bite of the Aedes aegypti mosquito, which also spreads dengue and chikungunya.
Brazil is experiencing the largest known outbreak of Zika.
The Zika virus has already killed five babies in the country, said the health ministry. Another 44 deaths are being investigated to determine if they were caused by Zika.
Last week, the Brazilian Health Minister Marcelo Castro said a new testing kit was being developed to identify quickly the presence of either of the three viruses.
