COVID-19 Weekly Epidemiological Update Summary

• Global Overview: As of 16 July 2023, over 768 million confirmed COVID-19 cases and over 6.9 million deaths reported globally. New cases and deaths decreased by 30% and 42% respectively in the past 28 days, but testing reduction means data may be incomplete and biased. Increases in hospitalizations and deaths are more reliable indicators of burden.

• Hospitalizations and ICU Admissions: New hospitalizations and ICU admissions decreased by 47% and 58% compared to the previous 28 days. Only 6% of countries reported consistent hospitalization data, with most showing decreases, though Malta saw a 46% increase in hospitalizations.

• SARS-CoV-2 Variants: WHO tracks variants of interest (e.g., XBB.1.5, XBB.1.16) and under monitoring (e.g., BA.2.75, EG.5). XBB.1.5 prevalence declined from 23.5% to 15.8%, while XBB.1.16 remained stable. No evidence of increased cases or severity for EG.5.

• WHO Regional Overviews: All six regions saw reductions in cases and deaths, with decreases ranging from -79% to -9%. Brazil, Australia, and the Republic of Korea reported high case increases, while deaths increased slightly in the Western Pacific Region (+30%). Regional data includes Americas (-36% cases, -13% deaths), Europe (-71% cases, -70% deaths), and others.
