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).

Zimbabwe has, over the years, grappled with the repercussions of the climate crisis, which have led to erratic rainfall patterns characterized by either severe floods or prolonged periods of drought. The nation has experienced a concerning trend of numerous regions reporting rainfall levels below th...e usual during what should be "normal" years. The upcoming El Niño event forecasted for 2023-2024, which is associated with drier-than-average rainfall, is poised to exacerbate this predicament. It is expected to intensify aridity, significantly impacting food and animal production across many areas, including those typically classified as "dry regions."
