Via the blog Cruise Law News: Are Cruise Ships Vectoring Chikungunya Virus to Florida? Excerpts:
Today I received a comment from a Royal Caribbean passenger who said that he was infected with the dreaded chikungunya virus when he sailed to St. Martin last year on the Oasis of the Seas:
You might need a new cruise category "Disease" as the cruise industry has become a vector for spreading the Caribbean epidemic of Chikungunya Fever virus to Florida . . . I got infected during my Oasis trip to St Martin last Dec - this thing is horrible and can be catastrophic for older passengers - one major "coincidental" cause of increased death among these folks isn't the virus ... it is suicide.
We have been contacted in the last 6 months by many cruisers concerned about being infected. But this is the first time that someone has contacted us after being bitten by an infected mosquito.
There has been a good amount of chatter on the cruise fan pages about the virus and fears of contracting it while cruising to the Caribbean.
Some but not all cruise lines warn about the disease.
