世界衛(wèi)生組織警告，寨卡病毒很可能會擴散到全美洲。到目前為止該病毒感染已擴及加勒比、北美和南美地區(qū)的 21 個國家。其中巴西出現(xiàn)的病例最多。今年夏天的奧林匹克運動會就將在巴西舉行。以下是 BBC Wyre Davies 從巴西發(fā)來的報道：

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 a surge 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 to travel to Zika-infected areas, including parts of Brazil. With concerns about the impact 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.
