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).

Globally, environmental pollution and other environmental risks cause 24% of all deaths, and these deaths are largely preventable. A shift towards policies and actions that minimize risks to health and promote health and sustainable personal and societal choices will reduce environmental risks to he...alth. These changes will result in many more people enjoying good health, living in appealing and unspoiled environments and in fewer people requiring health care, which will lower health care

Parasite Epidemiology and Control Volume 27, November 2024, e00380
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

Sudan has a long history of hosting refugees and asylum seekers with 991,787 individuals, 51 per cent female and 53 per cent children, expected to live in Sudan by the end of 2020.
For most people in displacement contexts, there are simply not enough vaccines available in the places where they are hosted: 85% of refugees are hosted in lower- and middle-income countries, while in the first six months of this year 85% of vaccines went to wealthy countries; lower- and middle inco...me countries have still received only a fraction of the vaccine doses they require.3 Shortages in these countries can also pose particular risks to vaccination campaigns aimed at displaced populations, as they can result in them being deprioritized.

El Niño conditions persisting during the 2015/16 planting season have caused the worst drought in 35 years in Southern Africa, resulting in a second consecutive failed harvest. This has created severe food shortages and compounded existing vulnerabilities. Since July 2016, Namibia and Botswana have... declared national drought emergencies, in addition to the declarations made earlier by Lesotho, Malawi, Swaziland and Zimbabwe. Madagascar issued a letter of solidarity with the SADC Appeal, and Mozambique has maintained a red alert in affected areas.
