This brief update on tuberculosis (TB) in the African region covers the state of TB in the WHO African region, strategic priorities and targets and the impact of COVID-19 on essential services. This is followed by key figures for the region, the role of WHO in country support and, recognizing the im...portance of diagnosis and drug susceptibility testing, a focus onstrengthening laboratory networks and the regional laboratory and diagnostic objectives. A brief update of the state of the science and how this is funded across the African region is provided, before closing with challenges and opportunities,strategic directions and a brief discussion of funding concerns. Discussions around the drivers of the disease, and issues of the poverty, inequality and stigma that continue to plague those living with TB are fully recognized, but are outside the scope of this report.

HIV infection, due to the immunosuppressant that leads, nowadays constitutes an aggravating factor of endemic tuberculosis. Tuberculosis remains a huge burden to human health, even in the early 21st century. The situation is deteriorating in many countries, particularly because of the synergy with t...he HIV epidemic and the emergence of multidrug-resistant (MDR) and extensively drug resistant (XDR) tuberculosis. The urgent development of new tools that can improve the diagnosis, prevention and/or treatment of tuberculosis and other major mycobacterium diseases depends largely on the progress of basic and applied research. Faced with this situation, there is an urgent need for effective strategies and actions to permanently solve the problem of this endemic disease whose impact is too negative on people’s lives.

Addressing comorbidities and risk factors for TB is a crucial component of Pillar one of the End TB Strategy, which focuses on integrated patient-centred care and prevention, including action on TB and comorbidities. The Framework for collaborative action on TB and comorbidities aims to support coun...tries in the evidence-informed introduction and scale-up of holistic people-centred services for TB, comorbidities and health-related risk factors, with the goal of comprehensively addressing TB and other co-existing health conditions. It should be used in conjunction with relevant WHO guidelines. The Framework is intended for use by people working in ministries of health, other relevant line-ministries, policymakers, international technical and funding organizations, researchers, nongovernmental and civil society organizations, as well as primary care workers, specialist health practitioners, and community health workers who support the response to TB and comorbidities in both the public and private sectors.

Three classess of tests are now recommended in the latest consolidated guideles on tests for tuberculosis infection. It includes for the first-time a new class of Mycobacterium tuberculosis antigen-based skin tests (TBSTs), and the two existing classes of tests: the tuberculin skin test (TST) and t...he interferon-gamma release assays (IGRAs).
IGRAs and TBSTs use Mycobacterium tuberculosis complex specific antigens and represent a significant advancement to TST which has been used for over half a century.

Undernutrition increases the risk of tuberculosis (TB) and in turn TB can lead to malnutrition. Undernutrition is therefore highly prevalent among people with TB. It has been demonstrated that undernutrition is a risk factor for progression from TB infection to active TB disease and that undernutrit...ion at the time of diagnosis of active TB is a predictor of increased risk of death and TB relapse. However, the evidence concerning the effect of nutritional supplementation on TB prevention and health outcomes among people with TB had not previously been systematically reviewed. This guideline provides guidance on the principles and recommendations for nutritional care and support of patients with TB as part of their regular TB care

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).
