COVID-19 Quarantine Guidelines Print


SDHD Quarantine Guidance 

Effective February 12, 2021, fully vaccinated persons with exposure to someone with suspected or confirmed COVID‐19 are not required to quarantine if they meet ALL of the following criteria:
     1. Are fully vaccinated (i.e., ≥2 weeks following receipt of the second dose in a
         2‐dose series, or ≥2 weeks following receipt of one dose of a single dose vaccine)
     2. Are within 3 months following receipt of the last dose in the series
     3. Have remained asymptomatic since the current COVID‐19 exposure
Individuals meeting the criteria must still continue to follow current guidance to protect themselves and others, including
     • Wearing a mask and staying at least 6 feet away from others
     • Covering coughs and sneezes and washing hands often
     • Following all CDC travel guidance
     • Following any applicable workplace or school guidance
Fully vaccinated people that do not quarantine following an exposure must watch for symptoms for 14 days following the exposure and if symptoms develop, they should be evaluated by a physician and tested for COVID-19 if clinically indicated.  
For more detailed post-vaccination quarantine guidance, see the IDPH Health Advisory.


Effective December 3, 2020 Siouxland District Health Department implemented the updated recommendations for the quarantine rules recently released by CDC and Iowa Department of Public Health.  

  • The CDC now allows for a 10-day quarantine for individuals exposed to COVID.  This replaces the former recommendation of 14 days.
  • The quarantine period may be shortened to as little as 7 days with a negative test under the following conditions:
    • The negative test cannot be collected more than 2 days prior to the quarantine end date.
      • Example – if the quarantine end date is 7 days, the test must be collected at least 5 days after the exposure. 
    • No symptoms of COVID have been observed at any point during the quarantine period.
    • Monitoring for symptoms needs to continue through Day 14 and the person should isolate immediately if symptoms develop. 
  • No quarantine period can be less than 7 full days.


    • Individuals will need to contact their medical provider or other testing locations to obtain tests that may shorten the quarantine period.
    • Testing for the purposes of shortening quarantine will be based on availability of adequate testing resources in the community and priority of testing should be given to those seeking evaluation for infection.
  • SDHD will NOT be able to:
    • Arrange for testing
    • Obtain copies of test results or send test results
    • Confirm or validate that all criteria for early quarantine release have been met.
  • It’s critical that people stay in quarantine for 10 days if they’ve had any COVID symptoms while in quarantine.
