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).

Trachoma is the leading infectious cause of blindness (2). It is characterized by repeated
conjunctival infection with particular strains of Chlamydia trachomatis. This scars the conjunctivae and,

Health care-associated infections (HAI) are one of the most common adverse events in care delivery and a major public health problem with an impact on morbidity, mortality and quality of life. At any one time, up to 7% of patients in developed and 10% in developing countries will acquire at least on...e HAI. These infections also present a significant economic burden at the societal level. However, a large percentage are preventable through effective infection prevention and control (IPC) measures.

Conflict, climate change, the COVID-19 pandemic, and the economic effects of the Ukraine crisis are interacting to create new and worsen existing hunger hotspots, reversing the gains families had made to escape poverty.
This manual presents a compelling case for action on carbapenem-resistant organisms (CROs) and describes the linkages between the prevention and control of CROs and the Global Action Plan on Antimicrobial Resistance (AMR). It describes how the eight recommendations contained within the World Health ...Organization (WHO) guidelines for the prevention and control of carbapenem-resistant Enterobacteriaceae, Acinetobacter baumannii and Pseudomonas aeruginosa in health care facilities relate to general measures (that is, the core components of infection prevention and control [IPC] programmes) that need to be in place in all countries and health care facilities to prevent and control health care-associated infections (HAIs). The use of a stepwise approach is proposed to support implementation and improvement, based on the evidence and experience of what has worked in several health care settings worldwide. The focus is on adoptable and adaptable information.

23 Dec 2020. The aim of this document is to provide an update on the knowledge surrounding the role of children in the transmission of SARS-CoV-2 and the role of schools in the COVID-19 pandemic, based on the experience in the EU from August–December, 2020. This document also addresses transmissio...n to and from staff in school settings, school-related mitigation measures including risk communication, testing, contact tracing and the efficacy of partial and full school closures. This document draws upon and updates evidence presented in the previous report from ECDC on this topic, which was published on August 6, 2020
