The WHO continuously reviews available data on SARS-CoV-2 variants of concern. For this version, the global epidemiological
situation of the COVID-19 pandemic as of 21 January 2022 – at a time when the Omicron VOC had been identified in 171
countries across all six WHO Regions and was rapidly re...placing Delta worldwide – was considered Omicron has a substantial growth advantage, higher secondary attack rates and a higher observed reproduction number than Delta.
There is now significant evidence that immune evasion contributes to the rapid spread of Omicron. Other factors may be a shorter
serial interval (by about 0.8 to 1.2 days compared to Delta) and potential increased intrinsic transmission fitness . There is
growing evidence that with Omicron, there is lower vaccine effectiveness (VE) against infection and symptomatic disease soon after vaccination compared to Delta. There is also evidence of accelerated waning of VE over time of the primary series against infection and symptomatic disease for the studied vaccines. Further studies are required to better understand the drivers of transmission and declining incidence in various settings. These factors include the intrinsic transmission fitness properties of the virus, degree of immune evasion, vaccination coverage and level of vaccine-derived and post-infection immunity, levels of social mixing and degree of application of public health and social measures (PHSM).

The report focuses on antibacterial resistance (ABR) in common bacterial pathogens. There is a major gap in knowledge about the magnitude of this problem. Antimicrobial resistance (AMR) threatens the effective revention and treatment of an ever-increasing range of infections caused by bacteria, para...sites, viruses and fungi. This WHO report, produced in collaboration with Member States and other partners, provides for the first time, as accurate a picture as is presently possible of the magnitude of AMR and the current state of surveillance globally. It examines the information on AMR, in particular antibacterial resistance (ABR), at country level worldwide.

The report presents current information (updated to September 2015) on candidate vaccines, therapies and medical devices for Ebola and gives an overview of completed and on-going trials.
This guidance document provides basic broad principles for a spokesperson
of any health authority on how to respond to vocal vaccine deniers.
The suggestions are based on psychological research on persuasion,
on research in public health, communication studies and on WHO risk
communication guide...lines.

Vector control is a vital component of malaria prevention, control and
elimination strategies because it can be highly effective in providing
personal protection and/or reducing disease transmission.
It is recommended that egg based quadrivalent vaccines for use in the 2019-2020 northern hemisphere influenza season contain the following:
an A/Brisbane/02/2018 (H1N1)pdm09-like virus;
an A(H3N2) virus to be announced on 21 March 2019*;
a B/Colorado/06/2017-like virus (B/Victoria/...2/87 lineage); and
a B/Phuket/3073/2013-like virus (B/Yamagata/16/88 lineage).
It is recommended that the influenza B virus component of trivalent vaccines for use in the 2019-2020 northern hemisphere influenza season be a B/Colorado/06/2017-like virus of the B/Victoria/2/87-lineage.
* In light of recent changes in the proportions of genetically and antigenically diverse A(H3N2) viruses, the recommendation for the A(H3N2) component has been postponed.

WHO has developed a clinical case definition of post COVID-19 condition by Delphi methodology that includes 12 domains, available for use in all settings. This first version was developed by patients, researchers and others, representing all WHO regions, with the understanding that the definition ma...y change as new evidence emerges and our understanding of the consequences of COVID-19 continues to evolve.
Post COVID-19 condition occurs in individuals with a history of probable or confirmed SARS CoV-2 infection, usually 3 months from the onset of COVID-19 with symptoms and that last for at least 2 months and cannot be explained by an alternative diagnosis. Common symptoms include fatigue, shortness of breath, cognitive dysfunction but also others and generally have an impact on everyday functioning. Symptoms may be new onset following initial recovery from an acute COVID-19 episode or persist from the initial illness. Symptoms may also fluctuate or relapse over time.

Die WHO hat mit Hilfe der Delphi-Methode eine klinische Falldefinition für das Post-COVID-19-Syndrom entwickelt, die 12 Domänen umfasst und in allen Bereichen verwendet werden kann. Diese erste Version wurde von Patienten, Forschern und anderen Personen aus allen WHO-Regionen entwickelt, wobei dav...on ausgegangen wird, dass sich die Definition ändern kann, wenn sich neue Erkenntnisse ergeben und sich unser Verständnis der Folgen von COVID-19 weiterentwickelt.
Die Post-COVID-19-Erkrankung tritt bei Personen mit einer wahrscheinlichen oder bestätigten SARS-CoV-2-Infektion in der Anamnese auf, in der Regel drei Monate nach dem Auftreten von COVID-19 mit Symptomen, die mindestens zwei Monate anhalten und nicht durch eine andere Diagnose erklärt werden können. Zu den häufigen Symptomen gehören Müdigkeit, Kurzatmigkeit, kognitive Störungen, aber auch andere Symptome, die sich im Allgemeinen auf das tägliche Leben auswirken. Die Symptome können nach der anfänglichen Genesung von einer akuten COVID-19-Episode neu auftreten oder nach der ersten Erkrankung fortbestehen. Die Symptome können auch schwanken oder im Laufe der Zeit wieder auftreten.

Personne ne se rend dans un établissement de soins de santé pour tomber malade. On s’y rend pour aller mieux, pour accoucher, pour se faire vacciner. Cependant, des centaines de millions de gens sont confrontés à un risque accru d’infection quand ils se font soigner dans des établissements ...de santé où les services de première nécessité font défaut, y compris les services d’approvisionnement en eau, d’assainissement et d’hygiène (WASH) et les services de gestion des déchets médicaux. Non seulement l’absence de services WASH dans les établissements de santé compromet la sécurité sanitaire des patients et leur dignité, mais il peut éventuellement exacerber la propagation d’infections résistant aux antimicrobiens et compromettre les efforts faits en vue de l’amélioration de la santé maternelle et infantile.

Prevention, early diagnosis, and effective treatment are essential for the control and elimination of Neisseria gonorrhoeae as a public health problem. Currently, in Latin America and the Caribbean, treatment for gonorrhea infection is largely empiric and based on clinical diagnosis. In the Americas..., the high burden of new N. gonorrhoeae infections (estimated at 11 million new cases a year), the complexity of the disease epidemiology, and in many countries the limited resources, make it difficult to fully understand the burden of disease and the burden of antimicrobial resistance (AMR) in N. gonorrhoeae.
PAHO has developed this document to facilitate the navigation of available guidance and recommendations for N. gonorrhoeae AMR surveillance by public health and health care professionals, at the national and subnational levels, involved in designing, implementing, and/or strengthening AMR surveillance of N. gonorrhoeae and overall surveillance of sexually transmitted infections.

Contact tracing is a key component of the COVID-19 response, particularly as societies begin to lift non-pharmaceutical interventions. However, it is a time-consuming and resource-intensive effort that depends on a trained and motivated workforce. Emergent digital contact tracing and quarantine (...DCTQ) tools offer the potential to complement and strengthen conventional contact tracing initiatives on an unprecedented scale. Despite their visibility throughout the pandemic

3rd edition. In 2001, Uganda adapted the Integrated Disease Surveillance and Response (IDSR) developed by World Health Organization (WHO) for member states in African region. The Ministry of Health has been implementing the IDSR strategy since then with success across the country. This strategy prov...ides the opportunity for rational use of resources and maximises investments in health surveillance systems. The 3rd edition IDSR guidelines incorporates lessons learnt from previous
epidemics, new frameworks like the Global Health Security Agenda (GHSA), One Health, Disaster Risk Management (DRM), the WHO regional strategy for health security and emergencies, and the rising non-communicable diseases, and aims to strengthen implementation of IHR (2005) core surveillance and response capacities. These guidelines have been adapted to reflect national priorities, policies and public health structures; and shall be used in conjunction with other similar
guidelines/strategies or initiatives.
Overall, the 3rd edition technical guidelines will incorporate the following:
• Strengthening Indicator Based Surveillance
• Strengthening Event Based Surveillance
• Improving community-based disease surveillance
• Improving Cross Border Surveillance and response
• Scaling up e-IDSR implementation
• Improving reporting and information sharing platforms
• Improved data sharing across sectors
• Tailoring IDSR to Emergency or Disaster contexts
The 3rd edition guidelines are intended for use as:
• A general reference for surveillance activities across all levels
• A set of definitions for thresholds that trigger some action for response
• A stand-alone reference for level-specific guidelines on surveillance and response
• A resource for developing training, supervision and evaluation of surveillance activities
• A guide for improving early detection and preparedness for outbreak response.
