Health Officer updates mega event guidelines following omicron surge in Highlands

In a pivotal meeting on July 4, 2025, the San Francisco City Commission addressed significant updates to health orders impacting mega events in the city. The executive director of Highlands presented crucial changes in response to the ongoing challenges posed by the highly transmissible omicron variant.

Starting January 15, the attendance threshold for indoor mega events will be reduced from 1,000 to 500 attendees, while outdoor events will now require a minimum of 5,000 participants. This adjustment aligns with the state's new definition of mega events. The health officer strongly recommends that attendees wear N95, KN95, or KF94 respirators, or a well-fitting surgical mask layered with a cloth mask.

A major highlight of the new health order is the requirement for patrons aged 16 and older to show proof of receiving a booster shot, effective February 1. This requirement applies to those eligible based on the timing of their vaccinations. Additionally, all staff at indoor mega events must also provide proof of their booster shots.

For indoor events with 1,000 or more attendees, organizers are mandated to submit a health and safety plan to the health officer. However, events with 500 to 999 attendees are exempt from this requirement. Outdoor mega events with 10,000 or more attendees will also need to submit a health and safety plan, while hosts are encouraged to verify booster shots for both patrons and staff.

The commission emphasized the importance of these updates, aiming to ensure public safety while allowing large gatherings to continue. Further communications will be sent to permit holders to remind them of the upcoming February 1 deadline for compliance.
