CDC: Frequent, Brief Contacts Can Fan Spread Of Coronavirus

The CDC has updated its guidelines, warning that even brief, repeated encounters can spread the disease. This change redefines 'close contact' to include cumulative interactions over 15 minutes within 24 hours. The update is based on new research showing that shorter, repeated contacts can lead to infection. Previously, the CDC recommended quarantine for those in proximity to an infected person for 15 minutes or more. Now, the recommendation includes cumulative contacts over a day.

What change has the CDC made regarding the definition of close contact?

• Close contact is only applicable in crowded places.

• Close contact is only defined by physical touch.

• Close contact requires being within 6 feet for 30 minutes.

• Close contact now includes brief, repeated encounters.

According to Dr. Robert Redfield, why was an update to the guidelines necessary?

• Because the previous guidelines were too strict.

• To align with international standards.

• Due to new research on cumulative contact time.

• To simplify the guidelines for the public.

What does the new research suggest about shorter contacts?

• They are less risky than previously thought.

• They can lead to infection if they add up to more than 15 minutes.

• They have no impact on the spread of the virus.

• They are only risky if they occur indoors.

What was the original CDC guideline for quarantine?

• Quarantine was required for any contact with an infected person.

• Quarantine was only for those with symptoms.

• Quarantine was for those in contact for 15 minutes or more.

• Quarantine was not required under any circumstances.

How has the CDC's recommendation changed regarding cumulative contacts?

• It requires quarantine only after 30 minutes of contact.
