“…Extreme caution should be exercised regarding the interpretation of the estimated prevalence for South America, due to selection biases observed during study review. These biases have been caused by the absence of information from several countries located far from the Amazon basin, as well as the use of data collected by studies conducted in the 1980s 1,2,5,6 and 1990s 3,4,[7][8][9][10][11][12][13][14][15][16][17]21 , which led to an overestimation of HDV infection cases in the studied area.…”

The information provided in this review revealed that almost all studies had cross-sectional designs [2][3][4][5][8][9][10][11][12][13][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29][30][31] as they fit prevalence studies; therefore, they did not provide information on relative time of exposure and outcome.

“…It is possible that the HDV prevalence reported in this evaluation may be overestimated, since the studies included in the meta-analysis were conducted with more vulnerable populations such as HIV-infected patients, hospitalized patients, health-care workers, injecting drug users and indigenous communities 1,2,[4][5][6][7][8]10,11,[13][14][15][16][17][18][21][22][23][24][25][26][27]30,31 . Discrepancies reported in the global epidemiology for HDV infection prevalence may be related to erroneous participant selection, generally not representative of general population or involving blood donors 1 , reinforcing once again that this estimated HDV infection prevalence in metaanalysis is restricted to the populations studied.…”

“…HDV infection is ubiquitous worldwide, but its distribution pattern is not uniform [1][2][3][4][5][6][7][8][9][10][11][12] .

Hepatitis delta virus (HDV) has been associated with acute or chronic hepatitis in Latin America, but there is no prevalence study covering South American countries. This meta-analysis aimed to estimate anti-HDV prevalence through a systematic review of published articles in English, Portuguese and Spanish until December 2017. Searches were conducted in Health Virtual Library, Capes, Lilacs, PubMed, and SciELO, according to defined criteria regarding participant selection and geographical setting. Study quality was assessed using the GRADE guidelines. Pooled anti-HDV prevalence was calculated using the DerSimonian-Laird random-effects model with Freeman-Tukey double arcsine transformation. Out of the 405 identified articles, only 31 met the eligibility criteria for inclusion in the meta-analysis. In South America, pooled anti-HDV prevalence among hepatitis B virus carriers was 22.37% (95% confidence interval: 13.72-32.26), though it appeared less frequently in some countries and populations, according to the data collection date. The findings indicated significant successive reductions in anti-HDV prevalence over thirty years. However, there was a scarcity of HDV epidemiological studies outside the Amazon Basin, notably in the Southwest continent and absence of target population standardization. There was a high HDV prevalence in South American countries, despite differences in methodological characteristics and outcomes, highlighting a drastic decline in the last decades. Future studies should identify HDV prevalence estimates in other regions of the continent and identify risk factors.

objective Hepatitis B virus (HBV) and hepatitis C virus (HCV) are prevalent in West Africa. To address the WHO 2030 goals of a 90% reduction in incidence and a 65% reduction in mortality for both infections, we assessed the prevalence of HBV and HCV from surveys in the general population.methods Participants in this cross-sectional survey were included from randomly selected houses in a demographic surveillance site in Bissau, Guinea-Bissau. Participants were interviewed and had a blood sample drawn for viral analyses (HBsAg, anti-HBs, anti-HBc, anti-HCV and HCV RNA). Risk factors of HBV and HCV infection were determined by binomial regression adjusted for sex and age.results A total of 2715 participants were included in this study. The overall HBsAg prevalence was 18.7% (95% CI: 17.3-20.2%). HBsAg was associated with male sex (adjusted risk ratio (aRR): 1.64), and prevalence decreased with age >34 years. HBV exposure was found in 91.9% of participants. Although 72.6% of individuals without sexual debut had been exposed to HBV, ever engaging in a sexual relationship was associated with higher risk of HBV exposure (aRR 1.18). The anti-HCV prevalence was 0.5% (95% CI: 0.3-0.9%), and 78.6% of those had detectable HCV RNA. Risk factors for anti-HCV sero-positivity were age above 55 (aRR 10.60), a history of blood transfusion (aRR 5.07) and being in a polygamous marriage (aRR 3.52).conclusion In Guinea-Bissau initiatives to implement treatment and widespread testing are needed to reach the WHO 2030 goals.keywords hepatitis B, hepatitis C, HIV, HIV-2, HTLV, Guinea-Bissau Sustainable Development Goals (SDGs): SDG 3 (good health and well-being), SDG 17 (partnerships for the goals)
