RESUMO

OBJECTIVES: Regular quality-assured WGS with antimicrobial resistance (AMR) and epidemiological data of patients is imperative to elucidate the shifting gonorrhoea epidemiology, nationally and internationally. We describe the dynamics of the gonococcal population in 11 cities in Brazil between 2017 and 2020 and elucidate emerging and disappearing gonococcal lineages associated with AMR, compare to Brazilian WGS and AMR data from 2015 to 2016, and explain recent changes in gonococcal AMR and gonorrhoea epidemiology. METHODS: WGS was performed using Illumina NextSeq 550 and genomes of 623 gonococcal isolates were used for downstream analysis. Molecular typing and AMR determinants were obtained and links between genomic lineages and AMR (determined by agar dilution/Etest) examined. RESULTS: Azithromycin resistance (15.6%, 97/623) had substantially increased and was mainly explained by clonal expansions of strains with 23S rRNA C2611T (mostly NG-STAR CC124) and mtr mosaics (mostly NG-STAR CC63, MLST ST9363). Resistance to ceftriaxone and cefixime remained at the same levels as in 2015-16, i.e. at 0% and 0.2% (1/623), respectively. Regarding novel gonorrhoea treatments, no known zoliflodacin-resistance gyrB mutations or gepotidacin-resistance gyrA mutations were found. Genomic lineages and sublineages showed a phylogenomic shift from sublineage A5 to sublineages A1-A4, while isolates within lineage B remained diverse in Brazil. CONCLUSIONS: Azithromycin resistance, mainly caused by 23S rRNA C2611T and mtrD mosaics/semi-mosaics, had substantially increased in Brazil. This mostly low-level azithromycin resistance may threaten the recommended ceftriaxone-azithromycin therapy, but the lack of ceftriaxone resistance is encouraging. Enhanced gonococcal AMR surveillance, including WGS, is imperative in Brazil and other Latin American and Caribbean countries.

RESUMO

BACKGROUND: Little is known about the aetiology of urethral discharge syndrome (UDS) and genital ulcer disease (GUD) in Brazil due to limited access to laboratory tests and treatment based mainly on the syndromic approach. OBJECTIVES: To update Brazilian treatment guidelines according to the current scenario, the first nationwide aetiological study for UDS and GUD was performed. METHODS: Male participants with urethral discharge (UD) and/or genital ulcer (GU) reports were enrolled. Sample collection was performed by 12 sentinel sites located in the five Brazilian regions. Between 2018 and 2020, 1141 UD and 208 GU samples were collected in a Universal Transport Medium-RT (Copan). A multiplex quantitative PCR kit (Seegene) was used to detect UD: Chlamydia trachomatis (CT), Mycoplasma genitalium (MG), M. hominis (MH), Neisseria gonorrhoeae (NG), Trichomonas vaginalis (TV), Ureaplasma parvum (UP), U. urealyticum (UU) and another kit to detect GU: cytomegalovirus (CMV), Haemophilus ducreyi (HD), herpes simplex virus type 1 (HSV1), herpes simplex virus type 2 (HSV2), lymphogranuloma venereum (LGV), Treponema pallidum (TP) and varicella-zoster virus (VZV). RESULTS: In UD samples, the frequency of pathogen detection was NG: 78.38%, CT: 25.6%, MG: 8.3%, UU: 10.4%, UP: 3.5%, MH: 3.5% and TV: 0.9%. Coinfection was assessed in 30.9% of samples, with 14.3% of NG/CT coinfection. The most frequent pathogen identified in GU was HSV2, present in 40.8% of the samples, followed by TP at 24.8%, LGV and CMV at 1%, and HSV1 at 0.4%. Coinfection of TP/HSV2 was detected in 4.4% of samples. VZV and HD were not detected. In 27.7% of the GU samples, no pathogen was detected. CONCLUSION: This study provided the acquisition of unprecedented data on the aetiology of UDS and GUD in Brazil, demonstrated the presence of a variety of pathogens in both sample types and reaffirmed the aetiologies known to be most prevalent globally.

RESUMO

BACKGROUND: The high-risk human papillomavirus (HR-HPV) infection is the main cause of cervical cancer development, and the most common types were included in the last approved nonavalent vaccine (9vHPV). Geographical, socioeconomic and ethnic barriers in developing countries challenge primary and secondary prevention measures of cervical cancer. We aimed to determine the prevalence of HPV infection and the viral load of HR-HPV 9vHPV-related types black women resident in rural semi-isolated communities. METHODS: A descriptive study was conducted with 273 cervical samples of women from rural communities of Southeastern Brazil. Viral DNA was amplified by PCR, the genotype was identified by Reverse Line Blot (RLB) and Restriction Fragment Length Polymorphism (RFLP), and real-time PCR was applied to determine the viral load. RESULTS: HPV frequency was 11.4% (31/273), associated with the presence of cytological abnormalities (32.3%; p < 0.001). Thirty-one distinct genotypes were detected; HR-HPV occurred in 64.5% (20/31) of the samples and the most prevalent type were HPV52 > 58, 59. Multiple infections occurred with up to nine different genotypes. The viral load of HR-HPV 9vHPV-related types was higher in lesions than in normal cytology cases (p = 0.04); "high" and "very high" viral load occurred in HSIL and LSIL, respectively (p = 0.04). CONCLUSIONS: We highlight that despite the low HPV frequency in the black rural women population, the frequency of HR-HPV was high, particularly by the HR-HPV52 and 58 types. Moreover, the HR-HPV viral load increased according to the progression from normal to lesion, being a potential biomarker to identify those women at higher risk of developing cervical lesions in this population.

RESUMO

BACKGROUND: Syphilis is a sexually and vertically transmitted infection caused by the bacteria Treponema pallidum for which there are few proven alternatives to penicillin for treatment. For pregnant women infected with syphilis, penicillin is the only WHO-recommended treatment that will treat the mother and cross the placenta to treat the unborn infant and prevent congenital syphilis. Recent shortages, national level stockouts as well as other barriers to penicillin use call for the urgent identification of alternative therapies to treat pregnant women infected with syphilis. METHODS: This prospective, randomized, non-comparative trial will enroll non-pregnant women aged 18 years and older with active syphilis, defined as a positive rapid treponemal and a positive non-treponemal RPR test with titer ≥1:16. Women will be a, domized in a 2:1 ratio to receive the oral third generation cephalosporin cefixime at a dose of 400 mg two times per day for 10 days (n = 140) or benzathine penicillin G 2.4 million units intramuscularly based on the stage of syphilis infection (n = 70). RPR titers will be collected at enrolment, and at three, six, and nine months following treatment. Participants experiencing a 4-fold (2 titer) decline by 6 months will be considered as having an adequate or curative treatment response. DISCUSSION: Demonstration of efficacy of cefixime in the treatment of active syphilis in this Phase 2 trial among non-pregnant women will inform a proposed randomized controlled trial to evaluate cefixime as an alternative treatment for pregnant women with active syphilis to evaluate prevention of congenital syphilis. TRIAL REGISTRATION: Trial identifier: www.Clinicaltrials.gov, NCT03752112. Registration Date: November 22, 2018.

RESUMO

BACKGROUND: Although there are public policies for eradicating congenital syphilis, they do not seem to be a routine in most health services. The objective of this study was to evaluate the management of sexual partners of pregnant women with syphilis in primary health care in northeastern Brazil. METHODS: This is a qualitative assessment carried out from February to October 2014 in the city of Fortaleza, Ceará, northeastern region of Brazil, through the observation of six primary health care centers and interviews with 21 professionals, six coordinators, nine women diagnosed with syphilis during antenatal care and four sexual partners. The data were submitted to thematic content analysis. RESULTS: Important flaws were identified at the primary health centers studied regarding the management of syphilis during pregnancy. Accessing testing and treatment is difficult, and there are no standardized strategies to notify the partner. The responsibility for notifying them is transferred to the women, and counseling does not offer proper guidance nor sufficient emotional support to help them. CONCLUSION: The management of pregnant women and their sexual partners in our region does not comply with global recommendations. Professional qualification, sensitization, and standardization of health professionals' conduct are necessary. Offering support to health professionals on their clinical practices by means of a supervision process may contribute to the adoption of the recommended guidelines and to the promotion of care based on privacy, respect, confidentiality of information, and awareness of the problems faced by women as a result of syphilis diagnosis.

RESUMO

BACKGROUND: The hypotheses put forward to explain the malaria transmission cycle in extra-Amazonian Brazil, an area of very low malaria incidence, are based on either a zoonotic scenario involving simian malaria, or a scenario in which asymptomatic carriers play an important role. OBJECTIVES: To determine the incidence of asymptomatic infection by detecting Plasmodium spp. DNA and its role in residual malaria transmission in a non-Amazonian region of Brazil. METHODS: Upon the report of the first malaria case in 2010 in the Atlantic Forest region of the state of Espírito Santo, inhabitants within a 2 km radius were invited to participate in a follow-up study. After providing signed informed consent forms, inhabitants filled out a questionnaire and gave blood samples for PCR, and thick and thin smears. Follow-up visits were performed every 3 months over a 21 month period, when new samples were collected and information was updated. RESULTS: Ninety-two individuals were initially included for follow-up. At the first collection, all of them were clearly asymptomatic. One individual was positive for Plasmodium vivax, one for Plasmodium malariae and one for both P. vivax and P. malariae, corresponding to a prevalence of 3.4% (2.3% for each species). During follow-up, four new PCR-positive cases (two for each species) were recorded, corresponding to an incidence of 2.5 infections per 100 person-years or 1.25 infections per 100 person-years for each species. A mathematical transmission model was applied, using a low frequency of human carriers and the vector density in the region, and calculated based on previous studies in the same locality whose results were subjected to a linear regression. This analysis suggests that the transmission chain is unlikely to be based solely on human carriers, regardless of whether they are symptomatic or not. CONCLUSION: The low incidence of cases and the low frequency of asymptomatic malaria carriers investigated make it unlikely that the transmission chain in the region is based solely on human hosts, as cases are isolated one from another by hundreds of kilometers and frequently by long periods of time, reinforcing instead the hypothesis of zoonotic transmission.

RESUMO

Mother-to-child transmission (MTCT) is the main mode of HIV-1 acquisition among young children worldwide. The goals of this study were to estimate the proportion of HIV MTCT and to identify factors associated with transmission. We reviewed data for HIV-infected pregnant women that had been reported to the National Information on Reportable Diseases System (SINAN) in Espírito Santo state, Brazil, between January 2007 and December 2012. HIV cases in children were followed until age 18 months. The proportion of women who transmitted HIV to their babies was 14% (95% CI 11-17%). In a multivariate logistic regression model, pregnant women who had lower than primary school education (OR 2.74; 95% CI 1.31-5.71), had 2 or more pregnancies during the study period (OR 2.28; 95% CI 1.07-4.84), had emergency cesarean delivery (OR 4.32; 95% CI 1.57-11.9), and did not receive antiretroviral therapy during prenatal care (OR 2.41; 95% CI 1.09-5.31) had higher odds of HIV MTCT. Effort should be made to encourage health care workers and pregnant women to use services for the prevention of MTCT.

RESUMO

We estimated mortality rate and predictors of death in children and adolescents who acquired HIV through mother-to-child transmission in Paraguay. In 2000-2014, we conducted a cohort study among children and adolescents aged < 15 years. We abstracted data from medical records and death certificates. We used the Cox proportional hazards model for the multivariable analysis of mortality predictors. A total of 302 subjects were included in the survey; 216 (71.5%) were younger than 5 years, 148 (51.0%) were male, and 214 (70.9%) resided in the Asunción metropolitan area. There were 52 (17.2%) deaths, resulting in an overall mortality rate of 2.06 deaths per 100 person-years. The children and adolescents with hemoglobin levels ≤ 9 g/dL at baseline had a 2-times higher hazard of death compared with those who had levels > 9 g/dL (HR 2.27, 95% CI 1.01-5.10). The mortality of HIV-infected children and adolescents in Paraguay is high, and anemia is associated with mortality. Improving prenatal screening to find cases earlier and improving pediatric follow-up are needed.

RESUMO

OBJECTIVES: To identify evidence that income, education, or ethnicity might be associated with low birthweight, small-for-gestational-age birth, or preterm birth. METHODS: A systematic review was conducted using searches in two online databases, PubMed and Literature in the Health Sciences in Latin America and the Caribbean (LILACS). The searches covered materials published between 1 January 1982 and 5 May 2016. The search terms used were ("infant, premature" OR "infant, small for gestational age" OR "fetal growth retardation") AND ("socioeconomic factors" OR "ethnic groups" OR "maternal age"). RESULTS: A total of 3 070 references that met the initial selection criteria were analyzed, and 157 relevant studies were fully read. We located 18 studies that investigated associations of family or maternal income, education, or ethnicity with low birthweight, small-for-gestational-age birth, or preterm birth. Of the 18, 10 of them involved high-income countries, and 8 dealt with middle- or low-income countries. Greater evidence was found for an association between ethnicity and the three outcomes studied, particularly for prematurity among children of black mothers. There was little evidence for an association between maternal/family income or education and any of the three outcomes. CONCLUSIONS: Income and education weren't determinants for low birthweight, small-for-gestational-age birth, or preterm birth. However, black ethnicity was strongly associated with the three outcomes, especially with prematurity.

RESUMO

BACKGROUND: Regions with residual transmission are potential obstacles to the elimination of malaria. It is, therefore, essential to understand the factors associated with the maintenance of endemic malaria in these areas. The objective was to investigate whether the status of asymptomatic carriers of Plasmodium spp. DNA is maintained in the long term in an extra-Amazonian region of Brazil with low incidence, residual malaria transmission. METHODS: Asymptomatic carriers of Plasmodium DNA detected in a survey carried out between 2001 and 2004 were reassessed between 2010 and 2011 using questionnaires, PCR and thick and thin blood smear tests three times at 3-month intervals. RESULTS: Of the 48 carriers detected between 2001 and 2004, 37 were located. Of these, only two had positive PCR results and, as in the first survey, Plasmodium malariae DNA was detected. CONCLUSION: The findings suggest that untreated dwellers from this extra-Amazonian region, who initially harbour malaria parasites, may become negative without ever developing apparent symptoms of the disease. Although the possibility of re-infection cannot be ruled out, the finding of two individuals harbouring P. malariae, both in the first and in the second survey, may be compatible with a long-term carrier state for this parasite. Since most clinical cases of malaria in the region are a consequence of infection by Plasmodium vivax, the epidemiological impact of such long-term carriage would be limited.

RESUMO

OBJECTIVE: To describe the epidemiological profile of reported cases of syphilis in pregnancy and congenital syphilis in five states (Amazonas, Ceará, Espírito Santo, Rio de Janeiro, and Rio Grande do Sul) and the Federal District using data from the Reportable Disease Information System (SINAN). METHOD: This descriptive study including an ecological and cross-sectional evaluation employed data from SINAN Net. The syphilis detection rate in pregnancy and the congenital syphilis incidence rate per 1 000 live births were calculated. To identify pregnant women with syphilis who had an outcome of congenital syphilis, the two SINAN databases were linked using the RecLink software. Because the data were representative at the state (not national) level, comparisons were made between the units of the federation and not with the sum of cases. RESULTS: A growth in the syphilis detection rate in pregnancy was detected, ranging from 21% (Amazonas) to 75% (Rio de Janeiro) during the study period. The incidence of congenital syphilis followed the same trend of growth (ranging from 35.6% in the Federal District to 63.9% in Rio Grande do Sul), except for a 0.7% decline in Amazonas. The proportion of women with an outcome of congenital syphilis who had prenatal care ranged from 67.3% in Amazonas to 83.3% in the Federal District. Of the pregnant women with syphilis, 43% had an outcome of congenital syphilis. In pregnant women with syphilis and an outcome of congenital syphilis, maternal diagnosis was made prenatally in 74% and at delivery in 18%. The moment of diagnosis was ignored in 8% of the women. CONCLUSION: The increase in the syphilis detection rate may have resulted from an increase in the report rate. Ongoing monitoring of pregnant women is essential to eliminate syphilis.

RESUMO

To compare the diagnostic performance for HPV infection using three laboratorial techniques. Ninty-five cervicovaginal samples were randomly selected; each was tested for HPV DNA and genotypes using 3 methods in parallel: Multiplex-PCR, the Nested PCR followed by Sanger sequencing, and the Next_Gen Sequencing (NGS) with two assays (NGS-A1, NGS-A2). The study was approved by the Brazilian National IRB (CONEP protocol 16,800). The prevalence of HPV by the NGS assays was higher than that using the Multiplex-PCR (64.2% vs. 45.2%, respectively; P = 0.001) and the Nested-PCR (64.2% vs. 49.5%, respectively; P = 0.003). NGS also showed better performance in detecting high-risk HPV (HR-HPV) and HPV16. There was a weak interobservers agreement between the results of Multiplex-PCR and Nested-PCR in relation to NGS for the diagnosis of HPV infection, and a moderate correlation for HR-HPV detection. Both NGS assays showed a strong correlation for detection of HPVs (k = 0.86), HR-HPVs (k = 0.91), HPV16 (k = 0.92) and HPV18 (k = 0.91). NGS is more sensitive than the traditional Sanger sequencing and the Multiplex PCR to genotype HPVs, with promising ability to detect multiple infections, and may have the potential to establish an alternative method for the diagnosis and genotyping of HPV.

RESUMO

OBJECTIVE: To describe the antiretroviral therapy status of people living with HIV (PLHIV) who died of AIDS-related causes between 2009 and 2013. METHODS: We conducted a cross-sectional, population-based study. Data were obtained by linking the mortality information system and the national ART dispensing database. Trends were modelled using linear regression analysis. RESULTS: A total of 61 425 AIDS-related deaths were registered in Brazil between 2009 and 2013. Median age at death was 41 years (IQR: 33-49), and 65.7% (40 337) of deaths were among men; 47.2% (29 004) of PLHIV who died during the study period had never started treatment, 7.0% (4274) had discontinued it, 15.9% (9775) were on ART for 6 months or less and 29.9% (18 372) were on ART for more than 6 months. Only 1.3% of PLHIV were on third-line ARV regimens when they died. CONCLUSIONS: AIDS-related mortality remains a challenge even in a context of sustained universal access to antiretroviral treatment due to failure of service provision, not to therapy failure. Robust health policies closing gaps in the HIV continuum of care are crucial to further reduce mortality.

RESUMO

BACKGROUND: Daily throughout 2011, about 900 new HIV infections occurred in children and 630 children died as a result of AIDS-related complications worldwide. Late diagnosis, mortality trends, causes of and risk factors for death were evaluated in vertically HIV-infected children. METHODS: A retrospective 11-year study was conducted with Brazilian vertically HIV-infected children and adolescents using patients' charts. Medical records, death certificates and the Ministry of Health's mortality database were verified for mortality and cause of death. Diagnoses were made according to the CDC Revised Classification System for HIV infection. RESULTS: Of 177 patients included, 97 were female (54.8%). Median age at admission was 30 months (IQR: 5-72 months). Median follow-up was 5 years (IQR: 2-8 years). After 11 years, 132 (74,6%) patients continued in follow-up, 11 (6.2%) had been transferred and 8 (4.5%) were lost to follow-up. Twenty-six deaths occurred (14,7%), the majority (16/26; 61.5%) in children<3 years of age. Death cases decreased over time and the distribution of deaths was homogenous over the years of evaluation. In 17/26 (65.4%) of the children who died, diagnosis had been made as the result of their becoming ill. Beginning antiretroviral therapy before 6 months of age was associated with being alive (OR=2.86; 95% CI: 1.12-7.25; p=0.027). The principal causes of death were severe bacterial infections (57%) and opportunistic infections (33.3%). CONCLUSIONS: In most of the HIV-infected children, diagnosis was late, increasing the risk of progression to AIDS and death due to delayed treatment. The mortality trend was constant, decreasing in the final two years of the study. Bacterial infections remain as the major cause of death. Improvements in prenatal care and pediatric monitoring are mandatory.

RESUMO

Our goal was to estimate prevalence of HIV among young women in labor. A national, probability-based, cross-sectional study was performed among pregnant women, aged 15-24 years, who were attending Brazilian public hospitals. The study included 2,071 of 2,400 women selected (86.3 % participation). Mean age was 20.2 years (SD = 2.7). HIV prevalence was 0.7 % (95 % CI, 0.4-1.1 %). Living in the North region of the country and having previous sexually transmitted infections were associated with HIV infection. Our survey of young pregnant women found higher prevalence than expected for women of all ages in Brazil (0.42 %), indicating that the epidemic persists among heterosexuals.

RESUMO

Our goal was to determine the prevalence of, and risk factors associated with, syphilis in HIV-infected patients who attend an AIDS outpatient clinic in Vitoria, Brazil. We conducted a cross-sectional study-including interviews for demographic, behavioral, and clinical characteristics-and blood collection (venipuncture and fingerstick) for VDRL and treponemal tests (rapid test) in a total of 438 patients. The mean age was 43.0 years (SD = 11), and mean years of school was 8.1 (SD = 4.2). The prevalence of syphilis was 5.3 % (95 % CI 3.3-7.3). The treponemal test was positive in 18.9 % of participants. In multivariate analysis, prevalent syphilis infection was independently associated with male gender (AOR 4.6, 95 % CI 1.1-20.0), a history of male-male sex (AOR 1.8, 95 % CI 1.6-4.1), current use of antiretroviral therapy (AOR 5.5, 95 % CI 1.7-16.7), and history of treated syphilis infection (AOR 5.5, 95 % CI 2.0-15.8). Syphilis prevalence was high in patients living with HIV/AIDS who attend an AIDS clinic; therefore, routine sexually transmitted infections counseling and screening should be included in their care.

RESUMO

BACKGROUND: Over the last decade tuberculosis (TB) incidence and mortality in Brazil have been steadily declining. However, this downward trend has not been observed among HIV-infected patients. We describe the epidemiological and clinical profile of TB patients by HIV status using the Brazilian National Surveillance System. METHODS: All TB diagnoses with HIV status information between January 1, 2007 and December 31, 2011 were categorized as either HIV or non-HIV at time of TB diagnosis. Co-infected patients (TB-HIV) were compared to TB patients with no HIV-infection using a hierarchical logistic regression model using Stata 13.0. RESULTS: The prevalence of TB-HIV co-infection was 19% among adults ≥ 15 years of age. We analyzed data from 243,676 individuals, of whom 46,466 were TB-HIV and 197,210 were only TB cases. The following factors increased risk of co-infection: male sex (OR: 1.06, 95% CI 1.03-1.10), 20 to 39 years of age (OR = 4.82, 95% CI 4.34-5.36), black (OR = 1.08, 95% CI 1.04-1.13), 4-7 years of education (OR = 1.13, 95% CI 1.19-1.28), diagnosed following default (OR = 2.65, 95% CI 1.13-6.25), presenting with pulmonary and extra-pulmonary forms of TB simultaneously (OR = 2.80, 95% CI 1.56-5.02), presenting with histopathologic examination suggestive of TB (OR = 2.15, 95% CI 1.13-4.07). Co-infected patients were less likely to live in rural areas (OR = 0.45, 95% CI 0.42-0.48), have diabetes (OR = 0.45, 95% CI 0.40-0.50) and be smear positive (OR = 0.55, 95% CI 0.32-0.95), and co-infected patients had higher risk of default (OR = 2.96, 95% CI 2.36-3.71) and death from TB (OR = 5.16, 95% CI 43.04-5.77). CONCLUSIONS: The prevalence of co-infection with HIV among TB patients is 19% in Brazil. By identifying predictors of co-infection targeted interventions can be developed to prevent both TB and HIV, and to diagnose each disease earlier and ultimately decrease poor treatment outcomes and death.

RESUMO

OBJECTIVE: The aim of the present study was to analyze the profile and trends of HIV mother-to-child transmission (MTCT) in the Brazilian land border strip (LBS). METHODS: This was a quantitative, ecological, and cross-sectional study using secondary data available in the information systems of the Brazilian Ministry of Health. All cases reported in the Notifiable Diseases Information System between 2010 and 2021 were studied. RESULTS: Between 2010 and 2021, 275 children were born infected through MTCT, and 6076 pregnant women were living with HIV in the Brazilian LBS. HIV detection rates in pregnant women increased in all border arcs. The northern arc experienced the highest increase (19.6%), followed by the central arc (11.4%), and the southern arc (6.1%). Despite historically high detection rates, the southern arc exhibited the smallest increase. While MTCT rate decreased by 37.7% in the border area, the central arc showed no statistically significant reduction. In 2021, the average age of pregnant women was 26.2 years, 25.7% had up to 8 years of schooling, and 55.8% identified as non-white. The majority (92.8%) received antenatal care, and 59.7% were diagnosed with HIV before prenatal care. The use of prophylactic antiretroviral therapy during prenatal care occurred in 69.6% of pregnant women, and infant prophylaxis was provided within first 24 h to 43.6% of live births. CONCLUSION: The results indicate progress in reducing MTCT cases in Brazilian LBS. Disparities in HIV detection rates may be influenced by differences in testing uptake, despite mandatory testing for all babies. It is crucial to continue implementing strategies to reach these women and ensure equitable access to healthcare services for MTCT prevention.

RESUMO

The worldwide monkeypox (mpox) outbreak in 2022 showed a high frequency of sexually transmitted infections (STI). A cross-sectional study was carried out using secondary data from the Brazilian official mpox surveillance systems. A total of 10,169 mpox cases were identified, with a median age of 32 years. Among them, 92.3% were male at birth and 57.5% were men who have sex with other men (MSM). Approximately 11% were diagnosed with STI, including 5.8% with syphilis and 2.5% with genital herpes. Individuals aged from 25 to 34 years, MSM, individuals with HIV-positive status, and those manifesting skin eruptions or penile edema were associated with STI. Laboratory investigation for mpox must be implemented as a priority in STI clinics (especially for MSM) to mitigate neglected cases, ensure appropriate treatments, and prevent misdiagnoses.
