Good morning,
Dr. Thannasi delivered an excellent presentation on TB exposures last week. During the session, we discussed a case involving someone who converted after just a 10-minute unprotected exposure to a smear-positive patient. This has prompted me to revisit our current policy regarding post-exposure testing and the amount of time exposed.

I’d appreciate learning more about your current guidelines:

  *   How do you determine the threshold for TB exposure duration?
  *   When do you initiate testing following an unprotected exposure?
