In response to increased COVID-19 infections throughout the Bay Area, Contra Costa Health (CCH) is advising residents to wear masks in crowded indoor settings, particularly those at high risk for severe illness if infected.

This is a recommendation, not a mandate, and aligns with state requirements and guidance from neighboring counties.

The current surge is driven by a highly contagious strain of COVID-19 known as FLiRT, which is spreading across the western U.S. Wastewater sampling in the county indicates a steady rise in the virus. From May 9 to July 9, COVID-19 concentrations in wastewater samples from the Central Contra Costa Sanitary District more than quadrupled. Although recent data shows a plateau, the levels remain high.

Health agencies in the Bay Area lifted most indoor mask mandates in February 2022 but continue to recommend masks during periods of high transmission, especially for those at higher risk.

“Face masks are an effective tool to reduce the spread of the virus, particularly for those who are at risk for serious illness when there is evidence of elevated COVID-19 activity in the community,” said Dr. Ori Tzvieli, Contra Costa County’s health officer. “This is one of those times. Our health system is not seriously impacted by COVID currently, and our goal is to keep it that way.”

A well-fitting mask, such as an N95 or KN95 respirator, is recommended for indoor public spaces, especially around those outside of your household.

Contra Costa's standing COVID-related health order requires healthcare facility workers to mask seasonally from November 1 to April 30 to reduce risks from COVID-19, flu, and respiratory syncytial virus (RSV). However, workers and visitors in healthcare and congregate care facilities are now strongly encouraged to mask.

Health guidance for schools and community colleges remains unchanged. With the new school year starting this month, CCH recommends that students and faculty, particularly those at risk, wear masks in classrooms. Schools are encouraged to provide masks upon request.

Other protective measures include staying current on vaccinations, testing for COVID-19 if symptomatic, and staying home if ill. Treatments for COVID-19 are available for those at risk of severe illness. Contact your healthcare provider for information on vaccination, testing, and treatment options.

An updated COVID-19 vaccine is expected by late summer or early fall. Home test kits are available through healthcare providers and pharmacies. Check with your provider or insurer regarding costs or copays for testing and test kits.
