Prevalence of cancer-associated viral infections in healthy afro-Caribbean populations: a review of the literature

Abstract

Cancer is one of the five leading causes of death in the Caribbean. Viral infections have been associated with cancer development and propagation, but the prevalence of such infections in the Caribbean is unknown. This review of the published literature shows that in 161,196 subjects from 14 Caribbean Islands, the adjusted prevalence of HHV8 infection is 4.5%, HTLV-1: 1.0%, HPV: 57.5%, HCV: 0.4%, HBV: 9.4%, and EBV: 92.2%. With the exception of HCV, the prevalence was significantly higher in the Caribbean than in the United States. These findings may significantly contribute to the high incidence of cancer observed in the Caribbean.
