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).

Based on scientific evidence, expert consensus and country experiences, the WHO core components for infection prevention and control (IPC) are the foundation for establishing or strengthening effective programmes at the national and facility level.
These new guidelines on core components of infecti...on prevention and control (IPC) at the national and acute health care facility level will enhance the capacity of Member States to develop and implement effective technical and behaviour modifying interventions. They form a key part of WHO strategies to prevent current and future threats from infectious diseases such as Ebola, strengthen health service resilience, help combat antimicrobial resistance (AMR) and improve the overall quality of health care delivery. They are also intended to support countries in the development of their own national protocols for IPC and AMR action plans and to support health care facilities as they develop or strengthen their own approaches to IPC.

In 2015, to advance the global and national response to antimicrobial resistance (AMR), the World Health Assembly issued resolution WHA68.7 calling for all Member States to develop AMR national action plans that address the five objectives of the World Health Organization Global Action Plan (GAP) by... May 2017. The WHO GAP provides a framework to support countries in developing their national action plans on AMR. To operationalize and accelerate implementation of national action plans on AMR, WHO has developed a costing and budgeting tool and accompanying user guide. The purpose is to support countries in costing prioritized activities of an operational plan linked to their AMR national action plan, and identify existing funding and funding gaps to promote resource mobilization and sustainable implementation. The target audience of the publication are national policy makers and designated costing coordinators for national action plans on AMR.

This Aide Memoire is for policy makers, immunization programme managers, infection prevention and control (IPC) focal points at national, sub-national, and facility level, as well as for health workers involved in COVID-19 vaccination delivery. This document summarizes the key IPC p...rinciples to consider and the precautions to take for safely delivering COVID-19 vaccines. The principles and recommendations provided in this document derive from World Health Organization (WHO) IPC and immunization standards and other guidance in the context of COVID-19. WHO will update these recommendations as new information becomes available. All technical guidance for COVID-19 is available online.

The planning and implementation of intervention measures against schistosomiasis, particularly mass administration, require knowledge of the current status of the infection. This is important for monitoring the impact of the interve...ntion on disease indicators such as a decline in infection prevalence, intensity of infection, and urogenital morbidities. Following repeated rounds of mass treatment in northwestern Tanzania, the epidemiology of urogenital schistosomiasis has changed; thus, for the effective planning and allocation of resources, it is important to understand the current status of the disease in the targeted groups

Poor sanitary conditions in disaster-stricken areas result in higher risk for diarrheal illness in vulnerable populations, especially children. This disease negatively impacts the nutritional status of affected children and causes significant morbidity and mortality. Early di...agnosis and treatment are thus essential to reduce the impact of diarrheal diseases on people affected by disasters. Early identification of cases allows the implementation of measures needed to prevent or lessen outbreaks that can occur in displaced populations in this context. The use of primary care management tools, such as the Integrated Management of Childhood Illness (IMCI) strategy is highly important.This module will first discuss diarrheal diseases and their management, and dehydration and its treatments.
