For the last several weeks there has been increasing respiratory virus activity in Orange County. Rates of COVID-19, Respiratory Syncytial Virus (RSV), and Influenza disease are all rising based on the percentage of positive test results reported to OCHCA. RSV activity has been increasing for the last 6 weeks, but more recently increases in influenza and COVID-19 activity have been detected. These patterns are in line with the regular seasonal epidemiology of these viruses.

Vaccines are now available for the prevention of disease caused by all three of these viruses. This season’s influenza and COVID-19 vaccines are recommended for all persons 6-month of age and older, while RSV vaccines or nirsevimab monoclonal antibody are recommended for select populations. Based on data reported to the California Immunization Registry (CAIR), ~740,000 influenza vaccines have been administered in Orange County through week 46, while only ~260,000 doses of the current season’s COVID-19 vaccines and ~ 52,000 doses of RSV vaccine have been administered.
