Contact tracing – along with robust testing, isolation and care of cases – is a key strategy for interrupting chains of transmission of SARS-CoV-2 and reducing mortality associated with COVID-19.
La recherche des contacts – associée à un dépistage rigoureux, à l’isolement et à la prise en charge des cas – est une stratégie clé pour interrompre les chaînes de transmission du SRAS-CoV-2 et réduire la mortalité associée à la COVID-19.
El rastreo de contactos, junto con las pruebas diagnósticas sólidas, el aislamiento y la atención de casos, es una estrategia fundamental para interrumpir las cadenas de transmisión del SARS-CoV-2 y reducir la mortalidad causada por la COVID-19.
Наряду с тщательным тестированием, изоляцией и уходом за заболевшими отслеживание контактов является ведущей стратегией для прерывания цепочек передачи вируса SA...RS-CoV -2 и снижения смертности, связанной с COVID-19.

Over 18 months into the pandemic, WHO continues to conductglobal surveillance of COVID-19as part of activities on preparedness, readiness and response activities. The need for global surveillance of COVID-19 is greater than ever, asthe implementation of vaccination campaigns and the appearance of va...riants are prone to impact the course of the epidemic, as transmission patterns evolve. Timely and complete surveillance data are key to monitoring these changes.
Features include stratification by age and sex, trends over time, case fatality ratios by age, testing, hospitalization, and data on health workers –all visible at country and regional levels. The dashboard provides the ability for users to conduct further analyses by country and selected time period.

Representative, quality, timely and continuous genetic surveillance of SARS-CoV-2 is critical to the COVID-19 outbreak response. This document provides practical guidance to Global Influenza Surveillance and Response System (GISRS) laboratories and other relevant national laboratories to move beyond... virus detection to genomic sequencing of SARS-CoV-2 PCR positive materials obtained from sentinel surveillance of influenza-like illness (ILI), acute respiratory infection (ARI) and severe acute respiratory infection (SARI). It contains considerations on sample selection for sequencing, numbers of viruses to be sequenced, metadata and timeliness for sharing genetic sequence data (GSD) and opportunities for technical support.

COVID-19 Vaccines: 1 Safety Surveillance 2 Manual
While there is no indication that pregnant women have an increased susceptibility to infection with SARS-CoV-2, there is evidence that pregnancy may increase the risk of severe illness and mortality from COVID-19 disease in comparison with non-pregn...ant women of reproductive age. As seen with non-pregnant women, a high proportion of pregnant women have asymptomatic SARS-CoV-2 infection and severe disease is associated with recognized medical (e.g., high body-mass index (BMI), diabetes, pre-existing pulmonary or cardiac conditions) and social (e.g., social deprivation, ethnicity) risk factors. Pregnant women with symptomatic COVID-19 appear to have an increased risk of intensive care unit admission, mechanical ventilation and death in comparison with non-pregnant women of reproductive age, although the absolute risks remain low. COVID-19 may increase the risk of preterm birth, compared with pregnant women without COVID-19, although the evidence is inconclusive.

This interim guidance is most useful for countries interested in monitoring relative circulations of influenza and SARS-CoV-2 viruses. The document provides practical information to maintain surveillance of influenza and monitor SARS-CoV-2 using e...xisting surveillance systems. It contains updated considerations for addressing disruptions in the influenza sentinel surveillance and extending to include COVID-19 wherever possible. Updated algorithms for testing of both influenza and SARS-CoV-2 for surveillance are also included. This document is an update of Operational considerations for COVID-19 surveillance using GISRS and GISRS for the upcoming influenza seasons during the COVID-19 pandemic

Since the emergence of COVID 19 in December 2019, various public health responses measures have been implemented to control the pandemic. Among measures taken by the Africa CDC was the launch of PACT initiative to accelerate COVID 19 testing. Key to the initiative is the engagement of Community Heal...th Workers (CHWs) in risk communication and community engagement (RCCE), surveillance activities for early case identification, contacts tracing and in facilitating referrals for testing and continuum of care.
As of 31 May 2021, Through PACT support, over 17154 CHWs have been trained and locally deployed in 24 AU Member states. The PACT supported CHWs visited more than 2,568,654 households for community engagement activities, active case search and contact tracing, identified 1,618,601 Contacts, 710,167 COVID 19 suspect cases based on the standard case definition and facilitated referrals for 553053 (78%) suspect cases for testing. These efforts were crucial for early identification and isolation of cases in limiting further transmission.
