This paper uses the internet-based biosurveillance to describe the Brazilian e-commerce of non-inspected dairy products and maps its traditional sale in a medium-sized city (Londrina). We searched the sales of illegal dairy products on Facebook Marketplace and conducted a census of street markets and a random sample of formal markets. Although prohibited in Brazil, consumers can easily find informal dairy products on internet and retail sale. In addition, 7% of the food products hold a false label to mimic food inspection. The e-commerce was linked with regions with higher access to technology and Human Development Index (HDI). We believe that our approach shows a step forward in the public health interventions and could be replicated stimulating debates about policies required to improve the public health surveillance.

OBJECTIVES: To discuss studies conducted in Brazil relating to PrEP, from 2012 to 2022, based on a narrative review. METHODOLOGY: The databases of the Virtual Health Library/PAHO, portals from Scielo, Scopus, and PubMed, and the descriptors in English and Portuguese 'Pre-exposure to HIV' and 'Brazil' were used, as well as a list of planned/in-progress demonstrative studies. Inclusion criteria consists of articles with fieldwork in Brazil coupled with PrEP in the Brazilian scenario; and articles in English or Portuguese. Articles in which PrEP was not the central theme and the participating Brazilian population did not reside in Brazil were excluded. RESULTS: 107 papers have been reviewed, 80 articles met the inclusion criteria. The majority participating population was men who have sex with men. 61 studies preceded the implementation of PrEP in Brazil. Studies carried out after implementation (n = 19) deal primarily with the impact of the COVID-19 pandemic. CONCLUSIONS: There was an incipient number of studies on the injectable form of PrEP. Fewer studies included segments with greater difficulties in access, use, and adherence. Despite the issues that circumscribe this prevention technology, literature is consensual on the importance of Brazilian leadership for implementing PrEP. [ABSTRACT FROM AUTHOR]

Community health workers (CHWs) are framed as the link between communities and the formal health system. CHWs must establish trusting relationships with the community and with the broader health service. How to find the optimal balance between the various strands of work for CHWs, and how to formalise this, has been the focus of different studies. We performed an extensive documentary analysis of federal legislation in Brazil to understand the institutionalisation of the CHW workforce in Brazil over the last 3 decades. The paper offers three contributions to the literature: the development and application of an analytical framework to consider the institutionalisation process of CHWs; a historical analysis of the professional institutionalisation of CHW in Brazil; and the identification of the paradoxes that such institutionalisation faces: firstly, institutionalisation focused on improving CHW remuneration created difficulties in hiring and paying these professionals; when CHW are incorporated within state bureaucracy they start to lose their autonomy as community agents; and that the effectiveness of CHW programmes depends on the improvement of clinical services in the most deprived areas.
