I'm a little nervous about going now having read about the Chikungunva Virus.
Chikungunya is no joke, but on the other hand the mortality (i.e., death) rate from the virus is basically zero. (That is, unlike other mosquito borne tropical illnesses, there are no confirmed cases of individuals that have died from this virus.) It is present throughout Puerto Rico - in fact, I have friends from the western part of the island where multiple individuals in the same family contracted Chikungunya last year. Although mortality is low in all age groups, I have heard that symptoms tend to be worst in the elderly and in people with pre-existing joint conditions, such as arthritis. Luckily no one in our family has yet been affected.
The good news is that the number of cases has declined greatly from last year to this year.
