COVID-19 Weekly Epidemiological Update
Edition 144 published 25 May 2023
In this edition:
• Global overview
• Hospitalizations and ICU admissions
• SARS-CoV-2 variants of interest and variants under monitoring
• WHO regional overviews
Global overview
Data as of 21 May 2023

Reported COVID-19 cases are underestimates of infection rates, largely due to the reductions in testing globally,and potential delays in reporting. During the reporting period (28 days) 161/243 (66%) countries reported at least one case. Data presented in this report are therefore incomplete and should be interpreted in light of changes in testing and surveillance. Additionally, data from previous weeks are continuously being updated to
incorporate retrospective changes in reported COVID-19 cases and deaths made by countries.
We present changes in epidemiological trends using a 28-day interval. Disaggregated data are still accessible on the WHO COVID-19 dashboard, where the full dataset is available for download.
