Workplace FAQ's

Adapted from the CDC Workplace Guidance

  • Send the positive case home immediately to isolate from others and prevent transmission 
  • Report the case to Hamilton County Public Health by filling out this form or calling the outbreak hotline, 513-946-7930 
  • Begin to contact trace and notify anyone who was within 6ft of the positive case for 15 minutes or more in the 2 days before the sick person first had any symptoms
    • But what if the positive case is vaccinated?
      • A positive case is treated the same, regardless of vaccination status. It is less likely for a vaccinated person to become infected, but it does occur due to the higher transmissibility of the current dominant viral strain.
    • But what if the close contact/person the positive case was around is vaccinated?
      • The vaccinated close contact should still be notified of their exposure so that they can mask and monitor for symptoms for 10 days after that exposure
    • How long should the positive case be home?
      • A positive case should follow CDC guidelines for how long to isolate, but generally 5 days at home and 5 days masked in public afterwards
    • How long should the close contact stay home?
      • If unvaccinated, a close contact should stay home for 5 days and then mask for 5 days after that when in public
    • Can a person test out of quarantine or isolation?
      • The CDC does not require testing to exit isolation or quarantine. However, testing on day 5 of quarantine and isolation can help reduce the risk of someone leaving their home while still infectious.
  • Masking In The Workplace:
    • Masks are designed to contain your respiratory droplets and particles. They also provide you some protection from particles expelled by others.
      • Cloth and disposable masks should fit over your nose and mouth to prevent leaks
      • Masks are more effective when they have multiple laters
      • Do not wear masks that gap around the sides of your face or nose, masks with valves or vents, or dirty masks
    • Respirators are designed to protect you from particles, including the virus that causes COVID-19, and in doing so they also contain your respiratory droplets and particles so you do not expose others.
      • N95 and KN95 masks are both examples of respirators
      • Only use NIOSH approved respirators
      • Check the seal of the respirator to make sure that it is tight to the face with no gaps
      • Do not use a respirator if you have certain types of facial hair, if it wet/dirty, if it has vents/valves, or if it is counterfeit
