“…Moreover, for campaigns targeting specific groups, such as SGM, they should be tailored to address their specific needs and concerns. There have been annual campaigns developed by the Brazilian Ministry of Health aimed at increasing HIV testing and promoting the use of condoms, most frequently released near Carnival [ 44 , 45 ]. On 1st December 2023, a technical note was released encouraging healthcare providers to incorporate the scientific evidence behind U = U and “zero risk” into HIV care [ 46 ].…”

IntroductionAlthough strong scientific evidence of the efficacy and effectiveness of treatment‐as‐prevention (TasP) is available, full endorsement of the “Undetectable = Untransmittable” (U = U) and “zero‐risk” messages could be improved. Increasing knowledge about HIV transmission, prevention and treatment is a critical component of care efforts. The study assessed knowledge of HIV transmission and prevention strategies, and the perceived accuracy of the slogan U = U among sexual and gender minorities (SGM) in Brazil.MethodsCross‐sectional web‐based survey targeting adult SGM living in Brazil (2021−2022) recruited on social media and dating apps. We used the 12‐item HIV Knowledge Assessment (HIV‐KA) questionnaire to assess HIV knowledge, three items of which address pre‐exposure prophylaxis (PrEP), post‐exposure prophylaxis and TasP. Perceived accuracy of the U = U slogan was assessed with the question: “With regards to HIV‐positive individuals transmitting HIV through sexual contact, how accurate do you believe the slogan U = U is?”. We a priori grouped the study population into three mutually exclusive groups: people living with HIV (PLHIV), HIV negative and HIV unknown. We used logistic regression models to assess factors associated with high HIV knowledge and perception of the U = U as completely accurate.ResultsOf 50,222 individuals accessing the questionnaire, 23,981 were included: 5071 (21.0%) PLHIV, 17,257 (71.5%) HIV negative and 1653 (6.9%) HIV unknown. The proportion of participants with high knowledge was significantly higher for PLHIV and HIV negative (48.1% and 45.5%, respectively) compared to 26.1% of HIV unknown. More PLHIV perceived U = U as completely accurate (80.4%), compared to 60.0% of HIV negative and 42.9% of HIV unknown. HIV knowledge correlates with perceived accuracy of the U = U slogan across all groups. Higher HIV knowledge was associated with higher income and education regardless of HIV status. Among HIV‐negative participants, PrEP awareness and use were associated with higher knowledge and accurate perception of the U = U slogan.ConclusionsOur findings show that HIV knowledge and perceived accuracy of U = U are strongly correlated, that knowledge differs according to HIV status, and that poor socio‐economic is linked to poor knowledge among SGM from Brazil. Educational strategies regarding TasP, U = U and zero risk targeting socio‐economically vulnerable populations are urgent in Brazil.

“…Public health communication campaigns are of prime importance for the continuous care of population health [ 6 , 7 ]. Over the years, governmental sectors have been increasingly investing in public health campaigns to promote public awareness regarding disease risk, as well as to disseminate diagnostic tests and treatment methods [ 8 ].…”

Background: The “Syphilis No!” campaign the Brazilian Ministry of Health (MoH) launched between November 2018 and March 2019, brought forward the concept "Test, Treat and Cure" to remind the population of the importance of syphilis prevention. In this context, this study aims to analyze the similarity of syphilis online news to comprehend how public health communication interventions influence media coverage of the syphilis issue. Methods: This paper presented a computational approach to assess the effectiveness of communication actions on a public health problem. Data were collected between January 2015 and December 2019 and processed using the Hermes ecosystem, which utilizes text mining and machine learning algorithms to cluster similar content. Results: Hermes identified 1049 google-indexed web pages containing the term ’syphilis’ in Brazil. Of these, 619 were categorized as news stories. In total, 157 were grouped into clusters of at least two similar news items and a single cluster with 462 news classified as “single” for not featuring similar news items. From these, 19 clusters were identified in the pre-campaign period, 23 during the campaign, and 115 in the post-campaign. Conclusions: The findings presented in this study show that the volume of syphilis-related news reports has increased in recent years and gained popularity after the SNP started, having been boosted during the campaign and escalating even after its completion.
