This applies to Phase 5 in all Illinois businesses, venues, and public spaces

The Illinois Department of Public Health recommends the following based on the CDC Interim Public Health Recommendations for Fully Vaccinated People:

  • Instruction for fully vaccinated people given new evidence on the B.1.617.2 (Delta) variant currently circulating in the United States
  • Fully vaccinated people should wear a mask in public indoor settings in areas of substantial or high transmission.
  • Fully vaccinated people might choose to wear a mask regardless of the level of transmission, particularly if they are immunocompromised or at increased risk for severe disease from COVID-19, or if they have someone in their household who is immunocompromised, at increased risk of severe disease or not fully vaccinated.
  • Fully vaccinated people who have a known exposure to someone with suspected or confirmed COVID-19 should be tested 3-5 days after exposure, and should wear a mask in public indoor settings for 14 days or until they receive a negative test result.
