9月4日、デング熱のウイルスを持った蚊が東京都渋谷区の都立代々木公園で見つかった。これを受けて東京都は同公園を午後2時から緊急封鎖したと発表した。
封鎖されたのは中央広場や噴水のある北側のA地区。都道413号線の南にある陸上競技場、サッカー場などのB地区は通常通り使用できる。封鎖は「当分の間」となっており、解除時期は未定だ。都は5日以降、蚊の駆除を急ぐ。
代々木公園内の10カ所で9月3日に採集した蚊について、デングウイルスを保有していないか調査したところ、4カ所からウイルスを保有した蚊が検出された。下の地図中の×印が検出された場所。5日以降、公園内の調査地点を20カ所に増やして、蚊のデングウイルス保有調査を強化する。
デング熱は蚊が媒介する感染症で、高熱が出る。厚労省は、代々木公園とその周辺で発生したデング熱の国内感染が、東京、神奈川、千葉に住む男女8人で新たに確認されたと4日に発表した。約70年ぶりに確認されたデング熱の国内感染は11都道府県在住の計55人になった。代々木公園やその周辺でウイルスを持った蚊に刺されて、感染したとみられる。
また、代々木公園に放送センターが隣接するNHKも4日、職員2人がデング熱に感染した疑いがあると発表している。MSN産経ニュースなどが伝えた。
ＮＨＫは４日、同局の女性職員１人と女性契約スタッフ１人の計２人がデング熱に感染した疑いがあると発表した。女性職員は入院中だが、命に別条はない。２人は「代々木公園周辺を訪れた」と話しているという。

TO GO WITH AFP STORY by Natalia Ramos\nA researcher examines transgenic Aedes aegypti mosquitos kept in cages to collect their eggs, at a laboratory of biotech company Oxitec, in Campinas, 100 km from Sao Paulo, Brazil, on August 21, 2014. Oxitec produces genetically modified mosquitoes to fight dengue, a deadly tropical disease more prevalent in Brazil than anywhere else in the world. The factory developed a technology where eggs of Aedes aegypti receive microinjection of DNA with genes that produce a protein which prevents their offsprings from reaching adulthood and thus reducing the total population of transmitters of dengue.

Noriega, 79, who was extradited from France in 2011, is serving three 20-year prison terms for the disappearance of opposition activists during his years in power (1983-89). The former dictator has been petitioning to be placed under house arrest since 2012, arguing that his ailing health warrants it. Noriega was toppled from power in a US invasion in 1989, and spent nearly two decades in prison in the United States and France on drug charges.
