Background Pre-treatment HIV drug resistance (HIVDR) to NNRTIs has consistently increased in low-/middle-income countries during the last decade. Objectives To estimate the prevalence of pre-treatment HIVDR and acquired HIVDR among persons living with HIV (PLHIV) on ART for 12 ± 3 months (ADR12) and ≥48 months (ADR48) in Honduras. Patients and methods A nationwide cross-sectional survey with a two-stage cluster sampling was conducted from October 2016 to November 2017. Twenty-two of 54 total ART clinics representing >90% of the national cohort of adults on ART were included. HIVDR was assessed for protease and reverse transcriptase Sanger sequences using the Stanford HIVdb tool. Results A total of 729 PLHIV were enrolled; 26.3% (95% CI 20.1%–33.5%) ART initiators reported prior exposure to antiretrovirals. Pre-treatment HIVDR prevalence was 26.9% (95% CI 20.2%–34.9%) to any antiretroviral and 25.9% (19.2%–33.9%) to NNRTIs. NNRTI pre-treatment HIVDR was higher in ART initiators with prior exposure to antiretrovirals (P = 0.001). Viral load (VL) suppression rate was 89.7% (85.1%–93.0%) in ADR12 and 67.9% (61.7%–73.6%) in ADR48. ADR12 to any drug among PLHIV with VL ≥1000 copies/mL was 86.1% (48.9%–97.6%); 67.1% (37.4%–87.5%) had HIVDR to both NNRTIs and NRTIs, and 3.8% (0.5%–25.2%) to PIs. ADR48 was 92.0% (86.8%–95.3%) to any drug; 78.1% (66.6%–86.5%) to both NNRTIs and NRTIs, and 7.3% (1.8%–25.1%) to PIs. Conclusions The high prevalence of NNRTI pre-treatment HIVDR observed in Honduras warrants consideration of non-NNRTI-based first-line regimens for ART initiation. Programmatic improvements in HIVDR monitoring and adherence support may also be considered.

Background: After serious epidemics of chikungunya (CHIKV) and Zika (ZIKV) in the Americas, dengue (DENV) have reemerged in most countries. We analyzed the incidence, incidence rates, and evolution of DENV cases in Honduras from 2015-2018 and the ongoing 2019 epidemic.Methods: Using epidemiological weeks (EW) surveillance data on the DENV in Honduras, we estimated incidence rates (cases/100,000 population), and developed maps at national, departmental, and municipal levels.Results: From 1 January 2016 to 21 July 2019, a total of 109,557 cases of DENV were reported, 28,603 in 2019, for an incidence rate of 312.32 cases/100,000 pop this year; 0.13% laboratoryconfirmed. The highest peak was reached on the EW 28°, 2019 (5,299 cases; 57.89 cases/100,000 pop). The department with the highest number of cases and incidence rate was Cortes (8,404 cases, 479.68 cases/100,000 pop in 2019). Discussion:The pattern and evolution of DENV epidemic in 2019 in Honduras has been similar to that which occurred for in 2015. As previously reported, this epidemic involved the north and central areas of the country predominantly, reaching municipality incidences there >1,000 cases/100,000 pop (1%). Studies using geographical information systems linked with clinical disease characteristics are necessary to attain accurate epidemiological data for public health systems. Such information is also useful for assessment of risk for travelers who visit specific areas in a destination country.
