The objective of the study was the validation and implementation of GeneXpert MTB/RIF for routine use in the rapid detection of tuberculosis and sensitivity to rifampicin in clinical samples; for this, 1592 respiratory samples were collected and analyzed in the laboratory of Instituto Nacional de In...vestigación en Salud Pública Guayaquil. The analysis of the results of GeneXpert in comparison with smear microscopy showed an initial sensitivity of 99.8% and specificity of 93.2%; The analysis of discrepancies using the results of the culture as a reference method showed that the GeneXpert results considered false negatives turned out to be true negatives, the same happens with the false positives that correspond to true positives. Recalculated the sensitivity and specificity of the GeneXpert was 99.8% and 100% correspondingly. The comparison with the drugs susceptibility test showed a sensitivity of 91.4% and a specificity of 95.5% for the GeneXpert MTB/RIF system. It is concluded that the implementation of the GeneXpert system allows solution to certain problems associated with the application of conventional diagnostic methodologies, decreasing the waiting times, and increasing the sensitivity and specificity in the diagnosis of drug-resistant tuberculosis, thus generating a valuable opportunity for early diagnosis.

This implementation brief addresses integration of HIV testing services into family planning (FP) services. It is intended as a practical resource for national health programmes seeking to introduce or scale up HIV testing and linkage to HIV prevention, sexually transmitted infection, and antiretrov...iral therapy services in FP.
This document highlights emerging good practices and country experiences of integrated HIV prevention and testing services within FP and advocates for increased linkage for FP clients to HIV services according to their needs. It also brings together information on models of integration of HIV testing into FP services, programme examples from east and southern Africa and guidance on the implementation monitoring process.

La détection directe des protéines virales du SRAS-CoV-2 (antigènes) dans les écouvillons nasaux et autres sécrétions respiratoires à l'aide de tests immunologiques à flux latéral (également appelés tests de diagnostic rapide, TDR) offre une méthode plus rapide et moins coûteuse pour te...ster le SRAS-CoV-2 que la méthode de référence, les tests d'amplification des acides nucléiques (TAAN). Ces lignes directrices provisoires offrent des recommandations sur les utilisations prioritaires des tests de diagnostic rapide à détection d'antigène (TDR-Ag) dans des populations et des contextes spécifiques, notamment (i) pour la détection primaire des cas chez les personnes symptomatiques suspectées d'être infectées et les personnes asymptomatiques à haut risque de COVID-19, (ii) pour la recherche des contacts, (iii) pendant les enquêtes sur les épidémies et (iv) pour surveiller les tendances de l'incidence de la maladie dans les communautés. Les TDR-AG répondant aux exigences minimales de performance peuvent être utilisés en dehors des milieux cliniques et des laboratoires, y compris dans les communautés, par des opérateurs formés conformément aux instructions. Le guide fournit en outre des recommandations sur la mise en œuvre, la sélection des produits et le stockage

The second edition of the joint WHO, WIPO and WTO
publication “Promoting Access to Medical Technologies
and Innovation: Intersections between public health,
intellectual property and trade” (the Trilateral Study),*
published in 2020, included a special insert mappi...ng the
challenges posed by the COVID-19 pandemic in relation
to the integrated health, trade and IP policy framework set
out in the study. The Trilateral Study and the special insert
were designed to serve as background reference for policy-
makers in the widest sense – lawmakers, government
officials, delegates to international organizations, non-
governmental organizations (NGOs) and researchers
who seek a comprehensive presentation of the full range
of issues, including institutions and legal concepts with
which they may be unfamiliar. It is also designed to serve
as a factual resource for the three organizations’ technical
cooperation activities.
This update revises the information contained in that
insert in the light of more recent developments as of
30 August 2021. Further updates will be made to reflect
subsequent developments.

Assessment and management of prolonged symptoms of COVID-19.
Introdução
Apesar de inicialmente ter sido considerada uma infecção aguda do sistema respiratório,
atualmente sabe-se do comprometimento multissistêmico e protraído da COVID-19 em alguns indivíduos [1]. Segundo dados prelimi...nares de estudos observacionais, estima-se que aproximadamente 10% dos pacientes com quadros leves a moderados de COVID-19 apresentam sintomas prolongados, que duram 3 semanas ou mais [2]. Essa condição tem sido chamada de COVID “longa”, “pós-aguda” ou
“síndrome pós-COVID-19”. Entre os pacientes que necessitam internação, especialmente em UTI, estes sintomas residuais podem ser muito mais frequentes: mais que 80% dos pacientes reportaram ao menos 1 sintoma após 60 dias do início do quadro.

As pandemias virais costumam representar sérias ameaças ao equilíbrio dos sistemas de saúde, ao impor-lhes demandas extraor-dinárias e sustentadas, que podem ultrapassar a capacidade de atendimento, no que diz respeito tanto aos insumos e às tecnologias disponíveis, quanto aos recurs...os humanos/profissionais capacitados. Trazem o enorme desafio de equilibrar igualdade entre as pessoas e equidade na distribuição de riscos e benefícios entre elas.
Diante desse cenário de casos cada vez mais frequentes de COVID-19 na
população, surge a premente necessidade de se avaliarem as melhores práticas para a otimização da utilização dos meios e recursos disponíveis. Dessa forma, considerando o iminente risco de indisponibilidade de leitos de terapia intensiva e respiradores para todos os indivíduos, acometidos ou não pela doença, torna-se fundamental estabelecer critérios clínicos, técnicos e éticos, para a melhor utilização dos mesmos, para se conseguir otimizar resultado e gerar o maior benefício possível.

This study aimed to analyze the geographical distribution of coronavirus disease 2019 (COVID-19) and to identify high-risk areas in space and time for the occurrence of cases and deaths in the indigenous population of Brazil. This is an ecological study carried out between 24 March and 26 October 20...20 whose units of analysis were the Special Indigenous Sanitary Districts. The Getis-Ord General G and Getis-Ord Gi* techniques were used to verify the spatial association of the phenomena and a retrospective space–time scan was performed. There were 32 041 confirmed cases of COVID-19 and 471 deaths. The non-randomness of cases (z score = 5.40; P < 0.001) and deaths (z score = 3.83; P < 0.001) were confirmed. Hotspots were identified for cases and deaths in the north and midwest regions of Brazil. Sixteen high-risk space–time clusters were identified for the occurrence of cases with a higher RR = 21.23 (P < 0.001) and four risk clusters for deaths with a higher RR = 80.33 (P < 0.001). These clusters were identified from 22 May and were active until 10 October 2020. The results indicate critical areas in the indigenous territories of Brazil and contribute to better directing the actions of control of COVID-19 in this population.

This bi-weekly brief details the latest developments in scientific knowledge and public health policy from around the world as well as updates to the COVID-19-related guidance from Africa CDC, WHO and other public health agencies.
Brazilian media and science communicators must understand the main characteristics of misinformation in social media about COVID-19, so that they can develop attractive, up-to-date and evidence-based content that helps to increase health literacy and counteract the spread of false information.
