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).

Lateral-flow rapid diagnostic tests (RDTs) continue to play a vital role in global health in the management and diagnosis of infectious diseases, including malaria, HIV and COVID-19. Visually interpreted RDTs, more than any other class of diagnostics, fulfil WHO’s ASSURED criteria,1 enabling their... use at the lowest levels of health care and in self-testing.2 Their utility is, however, compromised every time a test is incorrectly performed or interpreted or its result is not available in a timely manner for clinical decisionmaking and surveillance.

Gambiense human African trypanosomiasis is a deadly infectious disease affecting West and Central Africa, South Sudan and Uganda, and transmitted between humans by tsetse flies. The disease has caused several major epidemics, the latest one in the 1990s. Thanks to recent innovations such as rapid di...agnostic tests for population screening, a single-dose oral treatment and a highly efficient vector control strategy, interruption of transmission of the causative parasite is now within reach. If indeed gHAT has an exclusively human reservoir, this could even result in eradication of the disease. Even if there were an animal reservoir, on the basis of epidemiological data, it plays a limited role. Maintaining adequate postelimination surveillance in known historic foci, using the newly developed tools, should be sufficient to prevent any future resurgence.

This chapter discusses the antibacterial treatment of leprosy infections. Antibiotic treatment is
a key component of leprosy treatment, as it is vital to prevent the progression of the infection.
Treatment with rifampin and other antibiotics is highly effective and cures 98% of patients with
the ...leprosy infection. Furthermore, the relapse rate is very low, at about 1% over 5–10 years.
There is little M. leprae drug resistance in leprosy and few reports of multi-drug resistance (1, 2, 3,
4, 5, 6, 7, 8). An antibiotic treatment may take months or years to produce clinical improvement,
especially in patients with an initial high bacterial index (BI).

Recency assays use one or more biomarkers to identify whether HIV infection in a person is recent (usually within a year or less) or longstanding. Recency assays have been used to estimate incidence in representative cross-sectional surveys and in epidemiological studies to better understand the pat...terns and distributions of new and longstanding HIV infections.
This technical guidance outlines best practices regarding the appropriate use of HIV recency assays for surveillance purposes and updates 2011 technical guidance from the World Health Organization (WHO) and the Joint United Nations Programme on HIV/AIDS (UNAIDS) on the use of HIV recency assays.

The world is not on track to end the AIDS pandemic. New infections are rising and AIDS deaths are continuing in too many communities. This report reveals why: inequalities are holding us back. In frank terms, the report calls the world’s attention to the painful reality that dangerous inequalities... are undermining the AIDS response and jeopardising the health security of everyone. The report highlights three specific areas of inequality for which concrete action is immediately possible—gender
inequalities and harmful masculinities driving HIV; marginalisation and criminalisation of key populations, which our data show is resulting in starkly little progress for those populations and undermining the overall response; and
inequalities for children whose lives must matter more than their market share. But this is not a counsel of despair, it is a call to action. Through bold action to confront these inequalities, we can end AIDS.

Monitoring financial protection and utilization of health services in Mongolia 2009-2018 is based on national representative household socioeconomic surveys. The study finds that between 2009 and 2018, despite ambitious health reforms, the incidence of catastrophic health spending and impoverishing ...spending at the relative poverty line have increased. These increases were mainly driven by out-of-pocket spending on medicines and inpatient care. In the same period, inequity in access to and utilization of health services remained constant among population groups. Evidence suggests health financing policies need to be further strengthened to make progress towards universal health coverage. Continuous tracking of out-of-pocket payments and service utilization to inform policymaking is needed.

The harmful use of alcohol causes approximately 3 million deaths every year and the overall burden of disease and injuries attributable to alcohol consumption remains unacceptably high. The pace of development and implementation of alcohol policies has been uneven in WHO regions, and resources and c...apacities for implementation of the WHO Global strategy to reduce the harmful use of alcohol 10 years after its endorsement do not correspond to the magnitude of the problems. On this basis, the WHO Executive Board in its decision EB146 (14) called for accelerated action to reduce the harmful use of alcohol.
