世卫组织周二表示，留尼汪岛据信有数万人感染登革热。这个属于法国领土的岛屿是印度洋上的热门度假胜地。
Dengue is a set of viruses found in tropical and sub-tropical parts of the world. Humans get dengue from being bitten by mosquitos infected with the virus.
登革热是一种在全球热带和亚热带地区发现的病毒。被感染该病毒的蚊虫叮咬后会让人类患上登革热。
Health officials on the island told the WHO of the disease outbreak in March 2018. About 50,000 probable cases of the disease were reported between 2018 and April of this year. That includes 22,000 so far in 2019, the health agency said in a statement.
该岛上的卫生官员告诉世卫组织这种疾病于2108年3月爆发，2008年到今年4月期间报告了大约5万起疑似病例。该卫生机构在一份声明中表示，其中包括2019年迄今为止的2.2万例病例。
The WHO described the rise of confirmed and probable cases reported last year as unprecedented.
世卫组织称去年报告的确认和疑似病例的攀升是前所未有的。
There is no treatment. But with early discovery and good medical care, fewer than one percent of people infected die from the disease.

世卫组织称，自2018年留尼汪岛疫情爆发以来，已经有14人病死。该地区有86.65万人。

2017年到2018年世界各地的登革热病例数量有所下降，但是2019年出现了大幅增长，尤其是在越南、澳大利亚、柬埔寨、中国、老挝、马来西亚、菲律宾和新加坡。
