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).

Each year, the WHO Global TB Report provides a comprehensive and up-to-date assessment of the TB epidemic, and of progress in prevention, diagnosis and treatment of the disease, at global, regional and country levels. This is done in the context of global TB commitments, strategies and targets.
The... 2021 edition of the report has been produced in a new and more web-centric format. This is designed to make the content available in smaller (more “bite-sized”) chunks that are easier to read, digest, navigate and use. There is a short and slim report PDF with 30 pages of main content plus six short annexes. This is accompanied by expanded and more detailed digital content on web pages. The total amount of content remains similar to that of previous years.

Policy brief, 24 July 2020
The COVID-19 pandemic has affected older people disproportionately, especially those living in long-term care facilities. In many countries, evidence shows that more than 40% of COVID-19 related deaths have been linked to long-term care facilities, with figures being as h...igh as 80% in some high-income countries. Concerted action is needed to mitigate the impact across all aspects of long-term care, including home- and community-based care, given that most users and providers of care are those who are vulnerable to severe COVID-19.
This policy brief provides 11 policy objectives and key action points to prevent and manage COVID-19 across long-term care. Its intended audience is policy makers and authorities (national, subnational and local) involved in the COVID-19 pandemic. The brief builds on currently available evidence on the measures taken to prevent, prepare for and respond to the COVID‑19 pandemic across long-term care services including care providers

WHO has published the first-ever guidance on the clinical management of diphtheria. The only previously available guidance was an operational protocol. The new guidance followed the rigorous process for developing guidance at WHO.
It addresses the use of Diphtheria Antitoxin (DAT) in the treatmen...t of diphtheria. There is a worldwide shortage of DAT and evidence based recommendations on the use of DAT were requested by many Member States.
The guidance also includes new recommendations on antibiotics. In patients with suspected or confirmed diphtheria, WHO recommends using macrolide antibiotics (azithromycin, erythromycin) rather than penicillin antibiotics.
This clinical practice guideline has been rapidly developed recognizing the global increase in diphtheria outbreaks. Outbreaks of diphtheria in Nigeria, Guinea and neighbouring countries in 2023 have highlighted the urgent need for evidence-based clinical practice guidelines for the treatment of diphtheria. Given the sporadic nature of outbreaks, many clinicians in the affected regions have never managed acute diphtheria and its related complications. Diphtheria remains a neglected disease and vaccination is the top priority. At the same time, for patients with diphtheria, access to antibiotics, DAT and supportive care can be lifesaving.

Antimicrobial resistance (AMR) is a global public health crisis that resulted in 1.14 million deaths in 2021. According to the Institute for Health Metrics and Evaluation estimates, 96 416 of these deaths occurred in the World Health Organization (WHO) Eastern Mediterranean Region. All 22 countr...ies/territories in the Eastern Mediterranean Region are enrolled in the global AMR
surveillance system, and 17 countries/territories reported data in 2024 (for the year 2023). The total number of isolates reported to the system increased sixfold between 2017 and 2022, but the proportion of blood isolates is relatively very low. Most of the data come from public sector laboratories or hospitals, although the private sector has increased its participation in some countries/territories recently. Three pathogens account for three quarters of all the reported pathogens – Escherichia coli
(26%), Klebsiella pneumoniae (23%), and Staphylococcus aureus (22%).
