Chikungunya , a mosquito borne illness that causes fever and severe joint pain, has been spreading throughout several Caribbean territories since late last month .
Officials on the island of St. Martin, have begun vector control measures  to reduce the population of the aedes aegypti  mosquito, which is primarily responsible for the spread of the virus; regional netizens have been using Twitter to give updates:

American Science Professor and blogger Jeff Stratford predicted that it is only a matter of time until cases of the virus appear in the United States :
Why do I think Chukungunya is coming to the US? The virus is carried by mosquitoes are are ubiquitous throughout the Americas. All the virus needs to get a foothold in the US is for an infected individual (say a tourist) to bring the virus back to the Americas while the virus is circulating in their bloodstream. Then an “American” mosquito can bite the infected person, pick up the virus, and the cycle starts anew.
Since 2005, cases of the virus has been reported in over 40 countries  worldwide. You can keep track of the regional spread of the disease via Twitter, under the hashtags #chikungunya #caribbean .
