“…[8][9][10][11] A longitudinal study conducted among blood donors during 2005-2014 reported decreasing HBsAg prevalence from 3.95% in 2005 to 3.42% in 2014. 12 Among pregnant women in Haiti, the HBsAg prevalence was 5% in a study conducted in 2006 and 2.5% (95% CI: 1.7-3.4) in a study conducted in 2012. 13,14 Haiti is the only country in the AMR that is highly endemic for HBV (HBsAg prevalence > 7%).…”

In 2016, the World Health Assembly endorsed the Global Health Sector Strategy on Viral Hepatitis, which calls for elimination of hepatitis B virus (HBV) by 2030 (definition: £ 0.1% hepatitis B surface antigen [HBsAg] prevalence among children aged 5 years). The burden of chronic HBV infection among children in Haiti is unknown. We conducted a nationally representative cross-sectional serological survey among 5-to 7-year-old children based on a two-stage cluster design with two strata: West (includes metropolitan Port-au-Prince) and non-West (all other departments). We collected demographic, socioeconomic, and vaccination history data and tested for HBsAg using a rapid point-of-care test. We estimated HBsAg prevalence and evaluated the association of HBV infection with vaccination history, demographics, and socioeconomic characteristics.

“…Differences were found when analyzing the prevalence of HBsAg by continent of origin, even compared to other investigations carried out in the countries that mostly comprised the sample, such as Haiti and Venezuela [ 18 , 19 , 43 ]. In the present study, in Central America (n = 198), where Haitians predominated (89.4%), the frequency of HBsAg was 8.6% (n = 17/198; 95% CI: 5.4–13.3%), while among participants from South America (n = 152), especially Venezuelans (87.2%), it was 3.3% (n = 5/152; 95% CI: 1.4–7.5%).…”

Introduction: Eliminating hepatitis B and C in immigrant and refugee populations is a significant challenge worldwide. Given the lack of information in Brazil, this study aimed to estimate the prevalence of infections caused by hepatitis B and C viruses and factors associated with hepatitis B in immigrants and refugees residing in central Brazil. Methods: An observational, cross-sectional, and analytical study was conducted from July 2019 to January 2020 with 365 immigrants and refugees. Hepatitis B was detected by a rapid immunochromatographic test, enzyme immunoassay, and chemiluminescence, and hepatitis C by rapid immunochromatographic test. Multiple analysis was used to assess factors associated with hepatitis B infection. Results: Of the participants, 57.8% were from Haiti and 35.6% were from Venezuela. Most had been in Brazil for less than 2 years (71.2%). The prevalence of HBV infection and exposure was 6.6% (95% CI: 4.5–9.6%) and 27.9% (95% CI: 23.6–2.8%), respectively, and 34% had isolated anti-HBs positivity. Reporting a sexually transmitted infection was statistically associated with HBV infection (OR: 7.8; 95% CI: 2.3–26.4). No participant with positive anti-HCV serology was found. Conclusions: The study showed that participants were outside the reach of prevention and control actions for hepatitis B. Therefore, public health strategies must be designed to reach, inform, and vaccinate this group.

BackgroundViral hepatitis causes an important global health burden. In 2016, the World Health Assembly adopted an objective to globally eliminate this as a public health threat by 2030. However, significant gaps exist between countries in their progress. Haiti is the last country that has introduced infant hepatitis B vaccines into the routine immunization program in the Region of the Americas, and its schedule still does not incorporate birth dose vaccines. As the first step to raise awareness of viral hepatitis in this country, we conducted a systematic review and meta-analysis to estimate the prevalence of hepatitis B (HBV), C (HCV), and D (HDV) viruses in Haiti.MethodsWe searched PubMed, EMBASE, Web of Science and Scopus for studies reporting the prevalence of HBV, HCV and HDV among Haitian, with no language restriction, published until November 30th, 2021. Prevalence was pooled via a random-effects meta-analysis using a generalized linear mixed model with the logit link.ResultsOf 453 articles retrieved, 25 studies were included: 16 reported the prevalence of hepatitis B surface antigen (HBsAg), three for anti-HCV antibody, and six for both HBsAg and anti-HCV. No study was found for HDV prevalence. The pooled prevalence of HBsAg was 0.7% [95% confidence interval (CI): 0.3–1.4, I2 = 77.7%] among children, 3.5% (95% CI: 2.8–4.4, I2 = 93.2%) in the general adult population and 7.4% (95% CI: 4.0–13.3, I2 = 83.9%) in high-risk adult population. The pooled prevalence of anti-HCV antibody was 0.9% (95% CI: 0.6–1.4, I2 = 93.5%) among the general population and 1.4% (95% CI: 0.4–4.2, I2 = 0.0%) in high-risk adult population. No study reported the prevalence of anti-HCV antibody exclusively in children.InterpretationThe prevalence of blood-borne hepatitis, particularly that of HBV, is substantial in Haiti. The introduction of birth dose hepatitis B vaccines and improving access to testing and treatment services should be urgently considered to meet the elimination goal.Systematic review registrationhttps://www.crd.york.ac.uk/prospero/display_record.php?ID=CRD42022298081, identifier: PROSPERO (CRD42022298081).
