COVID-19 Weekly Epidemiological Update Summary

This edition of the weekly update covers global COVID-19 trends, hospitalizations, variants of interest, and regional data as of 9 July 2023. Key points include a decline in new cases and deaths globally, with challenges in data accuracy due to reduced testing. The analysis highlights regional variations and focuses on SARS-CoV-2 variants, including XBB.1.5 and XBB.1.16. Hospitalization rates have decreased, but some countries still show increases.

Global Overview

• Between 12 June and 9 July 2023, over 794,000 new COVID-19 cases and over 4800 deaths were reported worldwide (Table 1, Figure 1).
• Global cases and deaths are decreasing, but testing reduction means data may underestimate true incidence. Data for the report are incomplete due to continuous updates and reporting delays.
• Five WHO regions saw decreases in cases and deaths, but the African Region had a decline in cases with an increase in deaths, though from a low baseline. South-East Asia and the Americas showed significant drops in new cases and deaths.

Hospitalizations and ICU Admissions

• During a 28-day period, global hospitalizations and ICU admissions decreased by 47% and 66%, respectively, to 46,077 and 1063 new reports (Figure 4).
• Data are preliminary and may change; hospitalizations include both incidental and COVID-19-related cases. Only 16% of countries reported hospitalization data, with some countries like Malta and Bangladesh showing increases.

Variants of Interest and Variants Under Monitoring

• Key variants tracked include XBB.1.5 and XBB.1.16, with XBB.1.16 surpassing XBB.1.5 in prevalence. Trends show increasing circulation for some VUMs like XBB, XBB.1.9.2, and XBB.2.3 (Table 3).

WHO Regional Overviews

• Data for 12 June to 9 July 2023 show varying trends by region. The Americas saw the largest decrease in cases (-45%) but an increase in deaths. Africa had a moderate decline in cases but a sharp rise in deaths (+43%). Other regions like Europe and South-East Asia showed significant reductions. Variations exist due to different reporting practices and testing levels.
