More than 50,000 monkeypox cases have been recorded in the global outbreak, WHO figures showed Wednesday, though transmission is slowing in the virus hotspots of Europe and the United States.

世卫组织周三的数据显示,全球爆发的猴痘病例已超过5万例,不过在欧洲和美国的病毒热点地区,传播速度正在放缓。

The World Health Organization's dashboard listed the 50,000 cases and 16 deaths as reported this year to the U.N.Agency, which declared the outbreak a global public health emergency in July.

世界卫生组织的仪表盘列出了今年报告给联合国的5万例病例和16例死亡病例,联合国机构在7月宣布疫情为全球公共卫生紧急状态。

WHO chief Tedros Adhanom Ghebreyesus said the declines in new infections proved the outbreak could be halted.

世卫组织总干事谭德塞表示,新感染人数的下降证明疫情是可以被遏制的。

A toxic7 red tide is blamed for dead fish in the San Francisco Bay area in the western U.S. AP correspondent Lisa Dwyer reports.

据美联社记者丽莎·德怀尔报道,有毒的红潮导致了美国西部旧金山湾区的鱼类死亡。

An unprecedented8 red tide in the San Francisco Bay area is killing9 thousands of fish and other marine10 life whose carcasses are washing ashore11, creating a foul12 odor that experts say could get worse during this weekend's expected heat wave.

旧金山海湾地区一场史无前例的赤潮导致数以千计的鱼类和其他海洋生物死亡,它们的尸体被冲上岸,专家表示,在本周末预计的热浪期间,这种恶臭可能会变得更糟。

Crews have begun to remove dead crabs13, bat rays, striped bass14 and other fish that began piling up on the rocky shores of Oakland's Lake Merritt over the weekend.

工作人员已经开始清理死蟹、蝙蝠鱼、花斑鱼和其他鱼类,这些鱼周末开始堆积在奥克兰梅里特湖的岩石海岸上。

The fish die-off at Lake Merritt and at spots throughout the Bay Area maybe due to a harmful algae15 bloom that has been spreading across the bay since late July.

梅里特湖和整个湾区的鱼类死亡,可能是由于有害的藻类爆发,自7月下旬以来一直蔓延到整个海湾。

Most algae blooms end after a week or so.

大多数藻类的繁殖在一周左右后就会结束。

Officials say a years-long drought has prevented stagnant16 water from flowing into the ocean and unseasonably warm and sunny weather may be helping17 the algae spread.

官员们表示,长达一年的干旱阻止了积水流入海洋,而反常的温暖和阳光天气可能助长了藻类的蔓延。

Reports of dead fish started coming in last week.

上周开始陆续收到死鱼的报告。

I'm Lisa Dwyer.
