Abstract Introduction : The efficacy of pre‐exposure prophylaxis (PrEP) in preventing sexual acquisition human immunodeficiency virus (HIV) is well established. Little known about the feasibility PrEP implementation middle‐income settings with concentrated epidemics among men who have sex (MSM) and transgender women (TGW). Methods Brasil a prospective, multicentre, open‐label demonstration project assessing delivery context Brazilian Public Health System. HIV‐uninfected MSM TGW 3 referral...
We conducted a web-based survey to understand the impact of social distancing measures on Brazilian MSM and transgender/non-binary lives. A total 3486 respondents were included in this analysis great majority cismen (98%). The median age was 32 years (IQR: 27-40), 44% non-white, 36% low schooling 38% income.

Brazil accounts for almost half Latin American HIV cases Rio de Janeiro is city with second largest number AIDS. Clinical appointments pharmacy antiretroviral refills may be impaired due restricted traffic possible lockdowns, people living those using PrEP from accessing needed antiretrovirals. We hereby describe telemedicine...
Although gay, bisexual, and other cisgender men who have sex with (MSM) transgender women the highest HIV burden in Latin America, pre-exposure prophylaxis (PrEP) implementation is poor. We aimed to assess feasibility of same-day oral PrEP delivery Brazil, Mexico, Peru.Implementation (ImPrEP) was a prospective, single-arm, open-label, multicentre study conducted Brazil (14 sites), Mexico (four Peru (ten sites). MSM were eligible participate if they aged 18 years or older, HIV-negative,...
Abstract Introduction The HIV epidemic continues to disproportionately impact Latin‐American transgender women (TGW). We assessed factors associated with long‐term pre‐exposure prophylaxis (PrEP) engagement and adherence among TGW enrolled in the Implementation of PrEP (ImPrEP) study, largest demonstration study Latin America. Methods HIV‐negative aged ≥18 years reporting 1+eligibility criteria 6 months prior enrolment (e.g. sex partner known be living HIV, condomless anal [CAS],...
By October 30, 2022, 76,871 cases of mpox were reported worldwide, with 20,614 in Latin America. This study reports characteristics a case series suspected and confirmed at referral infectious diseases center Rio de Janeiro, Brazil.
Background The 2022 multicountry mpox outbreak positioned the condition as a public health emergency of international concern. By May 2023, Brazil ranked second globally in cumulative number cases and deaths. higher incidence among gay other men who have sex with current deepens stigma discrimination against sexual gender minorities (SGM). This might worsen structural barriers impacting access to services, which ultimately leads undertesting underreporting cases. There are no data available...
Brazil has the largest population of individuals living with HIV/AIDS in Latin America a disproportional prevalence infection among men who have sex (MSM). This study evaluated PrEP awareness by age (18-24, 25-35, ≥36 years), its associated factors and willingness to use HIV prevention technologies MSM using GSN app Brazil. Inclusion criteria were ≥18 years-old, cisgender HIV-negative serostatus. Of 7242 individuals, 4136 (57%) completed questionnaire. was reported 51% (though lower aged...
In March 2020, telemedicine and HIV self-testing were adopted by Brazilian Public Health services to minimize disruptions in pre-exposure prophylaxis (PrEP) access delivery during the COVID-19 pandemic. To understand acceptability of PrEP teleconsultation self-testing, we conducted a web-based study social distancing period (April–May, 2020) among men who have sex with transgender/non-binary individuals using media. Out 2375 negative respondents, 680 reported use included this analysis....
Abstract Introduction We aimed to evaluate daily oral pre‐exposure prophylaxis (PrEP) uptake, retention, and adherence predictors of study non‐attendance low PrEP in a Brazilian trans‐specific 48‐week (PrEParadas). Methods enrolled transgender women (TGW) engaging high‐risk sexual behaviours between August 2017 December 2018. was based on tenofovir diphosphate concentrations dried blood spots (DBS). used random effects logistic regression models ordinal estimate the odds having missed visit...

HIV incidence estimation is critical for monitoring the epidemic dynamics and effectiveness of public health prevention interventions. We aimed to identify sexual gender minorities (SGM) with recent infections, factors associated infection, estimate annualised rates.
Although strong scientific evidence of the efficacy and effectiveness treatment-as-prevention (TasP) is available, full endorsement "Undetectable = Untransmittable" (U U) "zero-risk" messages could be improved. Increasing knowledge about HIV transmission, prevention treatment a critical component care efforts. The study assessed transmission strategies, perceived accuracy slogan U among sexual gender minorities (SGM) in Brazil.
