世界卫生组织警告，寨卡病毒很可能会扩散到全美洲。到目前为止该病毒感染已扩及加勒比、北美和南美地区的 21 个国家。其中巴西出现的病例最多。今年夏天的奥林匹克运动会就将在巴西举行。以下是 BBC Wyre Davies 从巴西发来的报道：
Since first being detected in Brazil less than a year ago, the Zika virus has spread like wildfire and has now been reported across Latin America.

The virus usually only results in a mild rash and fever, but it's also been linked to asurge in microcephaly – a condition where babies are born with abnormally small heads.

Although the epicentre of the outbreak is in Northern Brazil, there've also been several cases of Zika in Rio de Janeiro. Olympic officials here say that in the run-up to this year's games they will inspect and if necessary fumigate areas where mosquitoes that transmit the disease might breed.

Some countries including the United States have advised pregnant women not totravel to Zika-infected areas, including parts of Brazil. With concerns about theimpact on athletes and spectators coming to Rio for the Games, the British Olympic Association told the BBC they've been liaising with the London School of Tropical Medicine and will be monitoring the situation closely.
