Close Contact in the Workplace: Think 6-15-24-48

The CDC has updated its definition of “close contact” and it is now referred to as the “6-15-24-48 analysis.” The updated guidance defines a “close contact” as someone who was:

  • within 6 feet of an infected person
  • for a cumulative total of 15 minutes or more
  • over a 24-hour period
  • starting from two days (48 hours) before illness onset (or, for asymptomatic patients, two days prior to test specimen collection) until the time the patient is isolated.

Employers who have employees experiencing COVID-related symptoms or who have tested positive for COVID should ask the employee to identify others with whom they were in close contact as described above. Note, the new definition now includes individuals with whom the employee was in contact for shorter periods of time that add up to 15 minutes or more within a 24 hour period. For example, this would cover contacts lasting five minutes at lunch, five minutes at the end of the workday, and 5 minutes the next morning.

As employers continue to monitor and respond to COVID-related situations in the workplace, they should update internal policies and procedures to match the current CDC guidelines, as well as guidance from their state or local public health departments or health orders.

As a reminder, these are the current CDC-designated symptoms of COVID-19:

  • Fever or chills
  • Cough
  • Shortness of breath or difficulty breathing
  • Fatigue
  • Muscle or body aches
  • Headache
  • New loss of taste or smell
  • Sore throat
  • Congestion or runny nose
  • Nausea or vomiting
  • Diarrhea
