In the overall assessment, the organizational component points to compliance with the recommended by the Ministry of Health, and the infrastructure component, accessibility indicated percentages that require advances to improve access.Keywords: Accessibility to Health Services, Health Centers, Primary Health Care. RESUMENObjectivos: Evaluar el acceso y la accesibilidad a las Unidades Básicas de Salud (UBS) en diferentes regiones de Brasil, multiplasándolas de acuerdo con los componentes organizativos y de infraestructura.

BackgroundThis cross-sectional study evaluated the prevalence of infection with human T-lymphotropic virus 1 and 2 (HTLV-1 and HTLV-2) in a population from the municipalities of Anajás, Chaves, São Sebastião da Boa Vista (SSBV) and Portel in the Marajó Archipelago and correlated these data with the epidemiological characteristics of the study population.MethodsA total of 1899 biological samples were evaluated. The samples were screened for the presence of anti-HTLV antibodies using an enzyme-linked immunosorbent assay (ELISA), and infection was confirmed using conventional polymerase chain reaction (PCR), real-time PCR and nucleotide sequencing.ResultsEleven samples (0.58%) were seropositive for HTLV, but molecular analysis confirmed positivity in only two samples (0.11%). Nucleotide sequencing and phylogenetic analysis indicated that the two samples positive for HTLV-1 that were isolated in Chaves belonged to the Cosmopolitan subtype 1 (HTLV-1a) and Transcontinental subgroup (A).ConclusionOur results confirmed the presence of Cosmopolitan Transcontinental HTLV-1 in the Marajó Archipelago, Amazon region, and the majority of the population revealed a lack of knowledge about sexually transmitted infections, which increases the risk of dissemination of HTLV and other agents.

Although the study indicates a low HIV-1 prevalence in Marajó Island, some factors may increase the risk for HIV-1 and these include early sexual initiation, unprotected sexual intercourse and the use of illicit drugs.

Background Colombia has the fourth highest incidence rate of HIV/AIDS among all Latin American countries and it has been increasing since the 1980s. However, the number of studies that addresses this trend is limited. Here, we employed spatial and temporal trend analyses to study the behaviour of the epidemic in the Colombian territory. Methods Our sample included 72,994 cases of HIV/AIDS and 21,898 AIDS-related deaths reported to the National Ministry of Health between 2008 and 2016. We employed the joinpoint regression model to analyse the annual HIV/AIDS incidence and AIDS mortality rates. In the spatial analysis, we used univariate autocorrelation techniques and the Kernel density estimator. Results While the HIV/AIDS incidence had an increasing trend in Colombia, the AIDS mortality rate was stable. HIV/AIDS incidence and AIDS mortality showed a downward trend in the 0–14 age group. An upward trend was observed for HIV/AIDS incidence in people older than 15 years and with the highest trend in the 65 years and above group. AIDS mortality showed an increasing trend among people aged 65 years or older. The comparison between the sexes showed an upward trend of HIV/AIDS incidence in all age groups and AIDS-mortality rates in 65 years and above in men, while in women, the incidence was upward among those aged 45 years and above, and concerning the AIDS-mortality rate in the 45–64 group. The high–high clusters of HIV/AIDS incidence and AIDS mortality were located in the Andean and Caribbean regions. Conclusion Our study found an upward trend in HIV/AIDS incidence and a stable trend in the AIDS mortality rate in Colombia. The downward trend in HIV/AIDS incidence and AIDS mortality rate in the 0–14 age group reflects the downwards mother-to-child HIV transmission. The upward trend in HIV/AIDS incidence in older women and AIDS mortality in younger women rates, compared with men, may be due to late diagnosis and treatment. The Caribbean and the ‘coffee belt’ regions were the most impacted by the HIV epidemic, most likely due to sexual tourism. Our results provide crucial information that may help Colombian health authorities fight HIV transmission.

ObjectiveTo analysis the epidemiological scenery of the congenital syphilis (CS) in Brazil employing spatial analysis techniques.DesignEcological study.SettingsThis study was conducted in BrazilSampleA total of 151 601 CS cases notified to the Diseases and Notification Information System from 2007 to 2018 from children aged 0–23 months and born from mothers living in Brazil were included in this study.Primary outcome measuresThe CS incidence rates were calculated by triad (2007–2010, 2011–2014 and 2015–2018) for all Brazilian municipalities following the Boxcox transformation to remove the discrepant values. The transformed rates were analysed through the spatial autocorrelation of Moran, Kernel density estimative and spatial scan.ResultsFrom 2007 to 2018, the CS incidence rates increased in all Brazilian regions. The CS spread towards the interior of Brazil, and a higher expansion was noticed between 2015 and 2018. The municipalities that were greatly affected by the CS were those having a high migration of people, such as the ones bordering other countries and the touristic cities. Recife, Campo Grande, Rio de Janeiro, Porto Alegre and Manaus were the capitals with the greatest spatial and spatiotemporal risk.ConclusionThis study provides assistance to health authorities to fight CS in Brazil. More investment is necessary in prenatal care quality focusing on pregnant women and their partners to guarantee their full access to preventive resources against sexually transmitted infections.
