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).

Ebola disease and Marburg disease outbreaks continue to occur in Africa, with increased frequency. In addition to resulting in high mortality and morbidity, the outbreaks generate fear and mistrust about the response activities within the communities affected.
Infection prevention and control (IP...C) is a key pillar in the outbreak response; adherence to IPC practices can prevent and control transmission of infections to health and care workers, patients and their family members.
During the 2014-2016 West African Ebola disease outbreak, there was an urgent need for rapid IPC guidance to help support ministries of health, health-care providers and non-governmental organizations (NGOs). In response, WHO produced several documents related to the outbreak based on expert opinion, including IPC-specific documents and documents on clinical management that also referenced key IPC principles and practices. Since that time, many practices in the field have become institutionalized.

Objective: The study aimed to describe the current epidemiological, clinical and immunological profile of newly
detected HIV - positive patients in Northern Benin by 2016. Methods: It was a prospective study conducted from May 2 to
October 31, 2016 on three main sites of care of people living with... HIV (PLHIV) in the department of Borgou in Benin. All
new cases of HIV infection have been systematically and comprehensively recruited. Initial epidemiological, clinical and
immunological data were collected using a questionnaire. These data were entered and analyzed using the Epi Info 7 software.
Results: In total, 185 adults (68 male and 117 female) newly screened HIV positive were included in this study. The middle age
was 36.2 ± 10.9 years and the sex ratio was 0.6 One hundred and thirty-five patients (73%) were between 25 and 50 years old.
In terms of the profession, 132 patients (71.3%) were engaged in liberal activities (craftmen, traders and retailers). The
majority was schooled (113 or 61.1%) and resided in urban areas (146 or 79%). One hundred and sixteen patients lived in
couple (62.7%) with an average monthly income estimated at 70 US Dollars. Clinically, 123 patients (66.5%) were in WHO
stage III. The body mass index was over 18.5 kg/m2 in 124 patients (67%). The median number of TCD4 lymphocytes was
254.5 cells/ml and 25 patients (13.5%) had a number of CD4 over 500 cells/ml. HIV1 was really predominant (97.8%). Most
patients (152 or 82.2%) had been screened for clinical suspicion. Conclusion: HIV infection in Benin remains the prerogative
of young, female, educated and poor people. Screening is delayed and hence the need to develop innovative strategies for early

The Ministry of Health of Saudi Arabia has developed the guidelines to meet the urgent need for up -to-date information and evidence-based recommendations
Joint WHO/ILO guidelines on post-exposure prophylaxis (PEP) to prevent HIV infection.
The revised guidelines contain recommendations for specific administrative, environmental controls and respiratory protection, following the assessment made by an external group of experts convened as members of the Guideline Development Group. Moreover, these guidelines focus on interventions speci...fic to preventing transmission of Mycobacterium tuberculosis bridging with the core components of infection prevention and control programmes at the national and acute health care facility level

Because of the limited access to more powerful diagnostic tools, there is a paucity of data regarding the burden of fungal infections in Burkina Faso. The aim of this study was to estimate the incidence and prevalence of serious fungal infections in this sub-Saharan country. We primarily used the na...tional demographic data and performed a PubMed search to retrieve all published papers on fungal infections from Burkina Faso and its surrounding West African countries. Considering the prevalence of HIV infection (0.8% of the population) and a 3.4% incidence of cryptococcosis in hospitals, it is estimated that 459 patients per year develop cryptococcosis. For pneumocystosis, it is suggested that 1013 new cases occur every year. Taking into account the local TB frequency (population prevalence at 0.052%), we estimate the prevalence of chronic pulmonary aspergillosis at 1120 cases. Severe forms of asthma with fungal sensitization and allergic bronchopulmonary aspergillosis are estimated to affect 7429 and 5628 cases, respectively. Vulvovaginal candidiasis may affect 179,000 women, and almost 1,000,000 children may suffer from tinea capitis. Globally, we estimate that roughly 1.4 million people in Burkina Faso (7.51% of the population) suffer from a serious fungal infection. These data should be used to drive future epidemiological studies, diagnostic approaches, and therapeutic strategies.

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).

Mortality due to enteric infections is projected to increase because of global warming; however, the different temperature sensitivities of major enteric pathogens have not yet been considered in projections on a global scale. We aimed to project global temperature-attributable enteric infection mor...tality under various future scenarios of sociodemographic development and climate change.

The Guidelines for the Prevention, Surveillance and Management of COVID-19 Infection amongst Health Care Workers (HCW) in Zimbabwe were developed to prevent, detect and manage HCW COVID-19 infection, an emerging pandemic affecting the whole world. The HCW is at the fore front of this pandemic, thus ...the need for standardised operating procedures is of utmost importance. These guidelines therefore seek to reduce the significant morbidity and mortality among the HCW, ultimately ensuring the reduction of the cost to the health care worker and the Ministry of Health and Child Care (MoHCC) as a whole. The Ministry of Health and Child Care requires that all health care workers in various health care settings follow infection prevention and control procedures.
