Quarantine Update

On March 11, 2022, the Michigan Department of Health and Human Services (MDHHS) released updated guidance for individuals exposed to someone with COVID-19. Under this new guidance, at-home quarantine for exposed individuals is not required in most situations, even if the exposed individual is unvaccinated. Exposed individuals can continue to come to work if they do not have any symptoms.

If the person was exposed to a personal or household contact (household member, sleepover, carpool, changing diapers, or direct exposure to respiratory secretions like kissing, sharing drinks, sharing smoking products, etc.):

  • Monitor for symptoms for 10 days.
  • Test at least one time if possible 3-7 days after exposure (if symptoms develop, definitely test).
  • Wear a well-fitting mask for 10 days (surgical, KN95 or N95 mask - not a cloth mask) from the date of last exposure to protect others. If unable or unwilling to mask, quarantine at home for 10 days.
  • Avoid unmasked activities or activities with higher risk of exposing vulnerable individuals for 10 days from the date of last exposure. 
  • If symptoms develop, avoid others and get tested (PCR or rapid antigen). If positive, follow isolation guidance. If negative, stay home until symptoms resolve. If symptoms worsen or change, follow up with a medical provider and consider getting another test.

If the person was exposed to someone who is not a personal or household contact (exposed in a community, social, or work setting):

  • Monitor for symptoms for 10 days.
  • Test if symptoms develop.
  • Consider wearing a well-fitting mask for 10 days from the date of last exposure to protect others. At a minimum, wear a mask in settings with higher risk of exposing vulnerable individuals.
  • Avoid unmasked activities or activities with higher risk of exposing vulnerable individuals for 10 days from the date of last exposure. 
  • If symptoms develop, avoid others and get tested (PCR or rapid antigen). If positive, follow isolation guidance. If negative, stay home until symptoms resolve. If symptoms worsen or change, follow up with a medical provider and consider getting another test.

CDC COVID-19 Community Level Update

The CDC published COVID-19 Community Levels as a tool to help determine prevention steps to take based on the latest data. Levels can be low, medium, or high, and are established by looking at hospital beds being used, hospital admissions, and the total number of new COVID-19 cases in an area. At "low" and "medium" levels, universal masking in indoor public settings is no longer broadly recommended according to the CDC. At all levels, people can wear a mask based on preference or increased risk for themselves or others. People with symptoms, a positive test, or exposure to someone with COVID-19 should wear a mask. If choosing to wear a mask, a multilayer, surgical, KN95, or N95 mask is recommended rather than a cloth mask.

Business Guidance & Resources

Although previous COVID-19 prevention strategies are no longer required for most settings, the Washtenaw County Health Department strongly encourages each facility to evaluate their operations, and to follow CDC and OSHA recommendations to prevent disease spread and protect worker and patron health and safety. (Note that healthcare settings have specific OSHA and MIOSHA requirements related to COVID-19.)
