Interim Guidance 31 march 2020
WHO has established a shipment mechanism to expedite and cover the costs of the shipment of clinical samples from patients with suspected COVID-19 from the country of collection to one of the WHO reference laboratories providing confirmatory molecular testing for COVI...D-19. This document explains the process and documentation required for shipment of specimens.

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.

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.

The main objectives of the training module
- facilitate communication and understanding between the two disciplines of epidemiology and laboratory (medicine) for disease surveillance and outbreak investigation;
- provide the field epidemiologist with a better understanding of basic microbiolo...gy techniques and analysis and interpretation of results;
- convey the laboratory perspective of public health investigations to field epidemiologists in order to improve collaboration between these two disciplines and to enhance.

This scientific brief replaces the WHO Scientific Brief entitled “’Immunity passports’ in the context of COVID-19”, published 24 April 2020.
This update is focused on what is currently understood about SARS-CoV-2 immunity from natural infection. More information about considera...tions on vaccine certificates or “passports” will be covered in an update of WHO interim guidance, as requested by the COVID-19 emergency committee.
