^The number of 7-day average daily cases is presented by episode date, an approximation of the date the illness began, and reflects data for the 7-day period ending Saturday. The number of 7-day average daily deaths is presented by date of death and reflects data for the 7-day period ending Monday with a three week lag. This is a change from how case and death data were presented prior to 7/27/23, which was by date of report. The 7-day average daily case count does not include Long Beach and Pasadena. The cumulative case count includes cases reported by Long Beach and Pasadena public health departments through 6/27/23. The 7-day average daily death count and cumulative death count both include Long Beach and Pasadena.

(1) COVID-associated illness is determined by ICD-10 diagnosis codes assigned to a patient upon discharge. The COVID-associated illness definition includes patients positive for COVID-19 with a pneumonia, acute respiratory distress syndrome, or acute cardiopulmonary diagnosis. A national standard definition for COVID-associated illness has not been developed; caution should be applied when comparing these estimates to estimates from other jurisdictions which may use different methods.
