Sequencing enabled the world to rapidly identify SARS-CoV-2 and develop diagnostic tests and other tools for outbreak management. Continued genome sequencing supports the monitoring of the disease’s spread and evolution of the virus. Accelerated integration of genome sequencing int...o the practices of the global health community is required if we want to be better prepared for the future threats. This document provides guidance for laboratories on maximizing the impact of SARS-CoV-2 sequencing now and other emerging pathogens in the future.

Issue Brief no.8. January 18,2021
Vaccination against the spread of the SARS-CoV-2 virus represents a milestone in the fight against the pandemic. Good communication and education of the population is essential for the success of the vaccination. Below is some information on vaccination strategies,... implementation of the vaccination, ethical considerations, as well as educational materials in English and other languages.

Genomic sequencing has been an essential tool in generating virological data, driving the laboratory response, and better understanding the dispersal and evolutionary patterns of SARS-CoV-2. In addition to the characterization of the global circulation patterns, early detection of SARS-CoV-2 variant...s inside each country is critical to complement the epidemiological and virological surveillance

14 July 2021 This article is part of a series of explainers on vaccine development and distribution. Learn more about vaccines – from how they work and how they’re made to ensuring safety and equitable access – in WHO’s Vaccines Explained series.
COVID-19 vaccines have proven to be safe, ...effective and life-saving. Like all vaccines, they do not fully protect everyone who is vaccinated, and we do not yet know how well they can prevent people from transmitting the virus to others. So as well as getting vaccinated, we must also continue with other measures to fight the pandemic.

In 2020, the COVID-19 pandemic impacted the world beyond imagination. To date, it has infected more than 135 million people, killed over 2.9 million people, and is projected to plunge up to 115 million people into extreme poverty.1 As countries have gone into lockdown, gender-based violence has incr...eased, unemployment has soared, and access to health care for the poorest and most vulnerable has been cut. COVID-19 has made people less likely to seek health care because they are afraid of getting infected with the virus. Fear and uncertainty surrounding COVID-19 have also increased stigma and discrimination. As frontline workers without enough access to personal protective equipment (PPE) risk their lives to treat patients, the virus pushes already fragile health systems to the brink.

The strategy recommends that AU Member States should enhance, where feasible, existing COVID-19 surveillance to include:
Community-based surveillance to detect symptomatic cases early for treatment and to avert viral transmission;
Sentinel surveillance in high-risk populations to detect ...and track both presymptomatic and asymptomatic cases; and
Wastewater surveillance to monitor early environmental signs of virus transmission and identify communities where targeted interventions can be implemented to decrease transmission.

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-

Contact tracing for COVID-19 is the process of identifying, assessing, and managing people who have been exposed to someone who has been infected with the SARS-CoV-2 virus, while quarantine is the separation of contacts from other people after exposure to a probable or confirmed case of SARS-CoV-2 i...nfection. In the context of growing global population immunity from COVID-19 vaccination and past SARS-CoV-2 infection, WHO recommends that identification, contact, quarantine and follow-up should be prioritized for individuals at high risk who have been in contact with a confirmed or probable case of SARS-CoV-2 infection, rather than targeting all contacts. This updated guidance also introduces shorter recommended quarantine periods, including the ability to further shorten quarantine through the use of testing. National and local health authorities should use risk-based approaches to contact tracing and quarantine that include reviewing and adjusting to their local circumstances and disease epidemiology, population immunity, their health system’s capacities, and risk tolerance.

Globally, more than 3 million new cases and 10 000 deaths have been reported in the week of 26 December 2022 to 1 January 2023. This represents a reduction in weekly cases and deaths of 22% and 12%, respectively. In the last 28 days (5 December 2022 to 1 January 2023), over 14.5 million cases and ov...er 46 000 new fatalities were reported globally – an increase of 25% and 21%, respectively, compared to the previous 28 days. As of 1 January 2023, over 656 million confirmed cases and over 6.6 million deaths have been reported globally.
In this edition, we include:
The COVID-19 epidemiological update at the global and regional levels.
An update on the circulating SARS-CoV-2 variants of concern (VOCs) and Omicron subvariants under monitoring.
An update on hospitalizations and ICU admissions related to COVID-19.

Leptospirosis is a zoonotic disease with epidemic potential, especially after a heavy rainfall,
caused by a bacterium called Leptospira. Leptospira interrogans is pathogenic to humans and
animals, with more than 200 serologic variants or serovars. Humans usually acquire
leptospirosis through dire...ct contact with the urine of infected animals or a urine-contaminated
environment. Human-to-human transmission occurs only very rarely. Leptospirosis may present
with a wide variety of clinical manifestations, from a mild illness that may progress to a serious
and sometimes fatal disease. Its symptoms may mimic many diseases, such as influenza,
dengue and other viral haemorrhagic diseases; making the correct diagnosis (clinical and
laboratory) at the onset of symptoms is important to prevent severe cases and save lives,
primarily in outbreak situations.

It is impossible to address the many complex needs of respiratory virus surveillance with a single surveillance system. Multiple systems, investigations and studies must each be fit-for-purpose to specific priority surveillance objectives, and only together can they provide essential information to ...policy-makers. In essence, each surveillance approach fit together as “tiles in a mosaic” that provides a complete picture of respiratory viruses and the impact of associated illnesses and interventions at the country level. This mosaic framework demonstrates how surveillance approaches may be implemented as coordinated and collaborative systems, well-matched to specific priority objectives.
