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.

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

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.

Coding of causes of death mentioning Multisystemic Inflammatory Syndrome associated with coronavirus disease
Since the description of the first case of COVID-19 in Wuhan, Hubei province in China, in December 2019, much knowledge has been accumulated about the dynamics of evolution of the SARS-CoV-2 virus, contagion, disease progression, prevention and treatment.

Recommendations for national testing strategies for SARS-CoV-2 and diagnostic capabilities
21 January 2022
The overall threat posed by Omicron largely depends on four key questions: (i) how transmissible the variant is; (ii) how well vaccines and prior infection protect against infection, transmission, clinical disease and death; (iii) how virulent the variant is compared to other varian...ts; and (iv) how populations understand these dynamics, perceive risk and follow control measures, including public health and social measures (PHSM).

It has been over a year since Kenya identified the first case of COVID-19 in the country. The Government formed the National COVID-19 task force, which supported the country's response through multi-sectoral technical working groups on testing, case management, risk communication and community engag...ement among others. An earlier version of the COVID case management guideline was released in April 2020 and capacity building of health care workers on diagnosis and treatment of COVID-19 was quickly carried out, even as counties prepared themselves by setting up isolation centres and supplies

his guidance provides interim guidance for the integration of SARS-CoV-2 and influenza virologic and genomic surveillance, from sentinel site case enrolment and sampling to the eventual sharing of the virus sequence data, a process known as end-to-end surveillance. This guidance builds on experience...s and lessons learned as countries adapted their influenza surveillance systems in the context of the COVID-19 pandemic and reviews new evidence to provide guidance on end-to-end surveillance. The guidance includes new algorithms and strategies to adapt sentinel systems to make them resilient and agile for addressing global and national surveillance needs for influenza and COVID-19.covid-
