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).

Epidemiological Update
Dengue
7 February 2020
Situation summary
In the Region of the Americas, between epidemiological week (EW) 1 and EW 521 of 2019, a total of 3,139,335 cases of dengue have been reported (321.58 cases per 100,000 population), including 1,538 deaths. Of the total cases, 1,367,...353 (43.6%) were laboratory-confirmed and 28,169 (0.9%) were classified as severe dengue. The case-fatality rate was 0.049%.

Worldwide, over 6 million people are infected with Trypanosoma cruzi, the pathogen that causes Chagas disease (CD). In the Americas, CD creates the greatest burden in disability-adjusted life years of any parasitic infection. In Co...lombia, 437 000 people are infected with T. cruzi, of whom 131 000 suffer from cardiomyopathy. Colombia’s annual costs for treating patients with advanced CD reach US$ 175 016 000. Although timely etiological treatment can significantly delay or prevent development of cardiomyopathy—and costs just US$ 30 per patient—fewer than 1% of people with CD in Colombia and elsewhere receive it.

Since the first edition of the CDAC snapshot of communication, community engagement and accountability (CCEA) across the Ukraine response was published in May 2022, a conscious effort has been made by international, national and local responders to ramp up CCEA action. Progress has been made in esta...blishing coordination mechanisms and launching activities, particularly around accountability to affected people (AAP). As CCEA work continues to scale up on the ground, a greater focus and more effort are still needed on community-facing information and two-way communication; this should be accorded a higher priority than at present.

The strategic framework gives guidance to public and private health facilities and health workers on compliance with standards relating to IPC practices. To further assist health facilities to implement the IPC strategic framework, this practical implementation manual has been developed in parallel ...to accompany the document.
These implementation strategies should be read in conjunction with the National Infection Prevention and Control (IPC) Strategic Framework (2020) to support an IPC programme at health facility level towards reducing healthcare-associated infections (HAI) and antimicrobial resistance (AMR). This manual is aligned with the World Health Organization (WHO) Core Component IPC programme recommendations and highlights the essentials for developing and improving IPC at health facility level in a systematic, stepwise manner for South Africa. It supports the Framework for the Prevention and Containment of AMR in South African Hospitals (2018).

Guidelines for the care and treatment of persons diagnosed with chronic hepatitis C virus infection
In the Region of the Americas, between epidemiological week (EW) 1 and EW 52 of 2018, a total of 560,586 cases of dengue were reported (incidence rate of 57.3 cases per 100,000 population), including 336 deaths. Of the total cases, 209,192 (37.3%) were laboratoryconfirmed and 3,535 (0.63%) were clas...sified as severe dengue. Cases reported in 2018 were higher than the total reported in 2017 but lower than the historical average reported in the previous 11 years (2006-2016) (Figure 1). Similarly, the proportion of cases of severe dengue and dengue with warning signs reported in 2018 was higher than the previous two years, but lower than the preceding ten years, and it remains below 1% which was reached in 2015.
