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).

For 100 cases among which 60 cases of children ≥ 5 years old and 40 cases of children < 5 years old and adults.
The new Pneumonia kit 2020 is specially designed to provide sufficient child-size antibiotics to treat pneumonia, targeting children under 5 years of age. It aims to provide life-savi...ng treatment based on the WHO protocols WHO treatment guidance Pneumonia should be treated with antibiotics.
The antibiotic of choice is amoxicillin dispersible tablets. Most cases of pneumonia require oral antibiotics, which are often prescribed at a health centre.

A guide to increasing coverage and equity in all communities in the African Region
Expanded Programs on Immunization (EPI) is responsible for vaccines and vaccination to control, eliminate and eradicate vaccine preventable diseases (VPDs). Having strong immunization systems to deliver vaccines ...to those who need them most will play a significant role in achieving the health, equity and economic objectives of several global development goals.

Risk of spill-over of EVD to Uganda has been categorised as very high. On 28 September 2018, WHO elevated the risk at the regional level which includes Uganda from ‘high’ to ‘very high’. Uganda has a very long and largely porous border with the DRC. High population movements across the borde...rs occur for various reason including for trade, social activities and services and asylum. There are cross-border markets in several border districts in Uganda and DRC that involve thousands of people crossing into and out of DRC and Uganda for trade purposes several days in a week.

Interim emergency guidelines
The following protocol has been designed to investigate the extent of infection, as determined by seropositivity in the general population, in any country in which COVID-19 virus infection has been reported. Each country may need to tailor some aspects of this protocol to align with public health, l...aboratory and clinical systems, according to capacity, availability of resources and cultural appropriateness. However, using a standardized protocol such as this one below, epidemiological exposure data and biological samples can be systematically collected and shared rapidly in a format that can be easily aggregated, tabulated and analyzed across many different settings globally for timely estimates of COVID-19 virus infection severity and attack rates, as well as to inform public health responses and policy decisions. This is particularly important in the context of a novel respiratory pathogen, such as COVID-19 virus
