Global Overview

The 118th edition, published on 16 November 2022, reports a 2% increase in global weekly COVID-19 cases during the week ending 13 November 2022, with over 2.3 million new cases recorded. However, testing declines suggest underreporting. New weekly deaths decreased by 30% to over 7400, from approximately 6.5 million cumulative deaths globally. Regional variations noted: cases declined in Europe, the Eastern Mediterranean, and Africa but increased in the Americas, Southeast Asia, and the Western Pacific. Deaths decreased across most regions.

Globally, Omicron and its sublineages accounted for 99.2% of sequences. BA.2.75, BQ.1, and XBB showed rising prevalence, while BA.5 declined. Limitations in surveillance systems affect data accuracy, including testing variations and sequencing delays.
