New COVID-19 CASES by Week in Los Angeles County
Each week ends on a Saturday. Updated each week on Saturdays, with the release of new data from Public Health.
Due to significantly reduced risks to the general public associated with COVID-19 infections, L.A. County Public Health retired their COVID-19 Data Dashboard, effective Mar. 1, 2025. The Almanac had long relied upon that source for ongoing COVID-19 data within Los Angeles County. Public Health will continue to provide some ongoing COVID-19 data (upon which we will now rely) through their weekly Respiratory Illness Surveillance Report. All case data in the chart below now reflects information from those reports.
Cumulative number of COVID-19 cases reported in 2024-2025 season (through Apr. 12, 2025): 2,414. Case numbers do not include data from the Long Beach and Pasadena health agencies. Keep in mind that many instances of COVID-19 infection today, if not most, are never reported to public health, but rather identified through at-home tests. Recovery is at home without ever visiting a medical facility.
COVID-19 DEATHS by Season in Los Angeles County
