Boulder County Current Status
Current Status: High Transmission, Masks Required
Boulder County Public Health is following the Centers for Disease Control and Prevention’s (CDC) comprehensive data tracking system to determine transmission levels. The CDC’s system tracks COVID-19 cases, hospitalizations, testing and other metrics to define four levels of community transmission, low, moderate, substantial and high, based on percent of positive tests and the number of cases per 100,000 people. The County Level View displays this information for Boulder County.
Boulder County is currently in:
- High Transmission, which is the highest level of transmission of COVID-19 under the CDC transmission tracker due to the Delta variant. All individuals 2+ are required to wear masks in all indoor settings regardless of vaccination status. View current facial covering requirements and recommendations.
- Masks are required in indoor spaces during periods of substantial and high transmission.
- If Boulder County is in substantial or high transmission status for five consecutive days, masks are required in public indoor spaces.
- Once transmission decreases to moderate or low levels for 21 consecutive days, masks will no longer be required in public indoor spaces. However, individuals may still choose to wear them, and businesses may still implement policies requiring them.
