The Caribbean enjoys a long-standing eminence as a popular tourist destination; however, over the years it has also amassed the sobriquet “arbovirus hotspot”. As the planet warms and vectors expand their habitats, a cognizant working knowledge of the lesser-known arboviruses and the factors that influence their emergence and resurgence becomes essential. The extant literature on Caribbean arboviruses is spread across decades of published literature and is quite often difficult to access, and, in some cases, is obsolete. Here, we look at the lesser-known arboviruses of the insular Caribbean and examine some of the drivers for their emergence and resurgence. We searched the scientific literature databases PubMed and Google Scholar for peer-reviewed literature as well as scholarly reports. We included articles and reports that describe works resulting in serological evidence of the presence of arboviruses and/or arbovirus isolations in the insular Caribbean. Studies without serological evidence and/or arbovirus isolations as well as those including dengue, chikungunya, Zika, and yellow fever were excluded. Of the 545 articles identified, 122 met the inclusion criteria. A total of 42 arboviruses were identified in the literature. These arboviruses and the drivers that affect their emergence/resurgence are discussed.

Dogs inThe Bahamas have been documented since the time of Columbus, so dogs have been residents of the country for at least as long as our written records. While the term "potcake" has been associated with mongrel dogs in The Bahamas for some time, written references have been traced back only as far as 1970. Since then, the written word potcake has become relatively common. Potcakes, while reviled by some, are considered as quintessentially Bahamian by others. This paper attempts to determine if the potcake is unique to The Bahamas. Our analysis of potcake DNA from New Providence and Grand Bahama suggests that the importation of dogs has diluted the pool of any ancient potcake DNA to an extent that the Bahamian potcake, if it ever existed, is now either extinct or highly admixed. Some implications for demystifying this Bahamian icon based upon the current welfare offered potcakes are proposed.
