Mongooses (Herpestes auropunctatus) have been introduced into most of the larger Caribbean islands, some notable exceptions being Dominica, Tobago, and Montserrat. Rabies in Caribbean mongooses is present in Puerto Rico, Cuba, the Dominican Republic (and presumably Haiti), and Grenada. Bat rabies is known on Cuba, Grenada, and Trinidad, although mongooses found on Trinidad are free of the disease. None of the other islands is known to have rabies, although it could be present in sequestered bat populations. All reported case numbers of mongoose rabies in the Caribbean are underestimates, and available information is at best incomplete and at times fragmentary. Nevertheless, data are presented from the four affected islands. Mongoose reduction campaigns have been undertaken on Cuba and Grenada. In Cuba strychnine sulfate inoculated into labeled eggs is used, whereas in Grenada sodium fluoroacetate (1080) has been used in boiled cowhide baits. Mongoose poisoning is unsatisfactory and ineffective in the long-term. Because many mongooses naturally exposed to rabies virus develop serum neutralizing antibodies and are considered to be immunized, possibly for life, vaccination in the wild has been under consideration since the mid-1970s. Early attempts to produce a pill coated with ERA vaccine for enteric absorption in mongooses were not very successful, but new modified vaccines and recombinant techniques hold considerable promise.
