Abstract
INTRODUCTION There have been several advances in the treatment of hepatitis C virus (HCV) infection which have resulted in major reductions in the morbidity and mortality from liver-associated disease. These are not widely available in the Caribbean, due in part, to lack of knowledge of the epidemiology of infections with HCV. As efforts are made to eliminate HCV from the region, these and other existing barriers such as lack of an established database on HCV must be addressed. This review seeks to identify gaps in the knowledge of HCV in the Caribbean with respect to seroprevalence, genotype distribution and general epidemiologic characteristics. MATERIALS AND METHODS The literature for the period January 1, 2005, to October 2022, was reviewed to gather country specific data on HCV across the Caribbean. References were identified through indexed journals accessed through established databases. The usage pattern of HCV drugs was determined from data obtained from Pharmacists and Infectious Diseases Specialists across the region. RESULTS The prevalence of HCV in the Caribbean was 1.5%; the region should therefore be considered an area of moderate prevalence. Notably, data from specific countries were limited. The prevalence of HCV among intravenous drug users (21.9-58.8%); persons living with HIV/AIDS (0.8 to 58.5%); prisoners (32.8-64%) and men who have sex with men (MSM) (0.8-6.9%) was generally higher than in the general population (0.8-2.3%). Genotype 1 (83% was most prevalent followed by genotypes 2 (7.2%) and 3(2.1%), respectively. Drugs currently being used for treatment of HCV infections across the Caribbean include Epclusa (Sofosbuvir/velpatasvir), and Harvoni (Ledipasvir/sofosbuvir). Some of these drugs, are only available in the private sector and are sourced externally whenever needed. CONCLUSION There is a paucity of current data on the seroprevalence of HCV in the Caribbean and well-designed prospective studies are indicated to drive the implementation of treatment and control programs for HCV in the region. Barriers which need to be first overcome include unavailability and high cost of drugs used to treat HCV infections, injecting drug use and limited access to medical care and laboratory testing.
