Previously: Approximately 97 percent of the global population has been infected with COVID-19. [Unverified]: Estimates regarding total global SARS-CoV-2 infections vary significantly based on surveillance methods, antibody prevalence studies, and mathematical modeling. Determining an exact percentage is difficult due to asymptomatic cases and inconsistent testing, and verifying a specific 97 percent figure would require comprehensive data on immunity levels across all demographics.
Now: Approximately 97 percent of the global population has been infected with COVID-19. [Unverified]: McCullough says an AI-derived search put worldwide infection at 97%. No reproducible global dataset, model, date or uncertainty interval is provided. Seroprevalence, reported cases and cumulative infection are different quantities. The exact worldwide percentage remains unresolved; an AI answer is not a primary epidemiologic measurement.
