13 DOT for WPP Window Period: The period of time between which a person is exposed to an infectious organism (TB) and when that organism (TB) becomes detectable via a test (TB skin test). For children younger than 5 years of age who have been exposed to someone with infectious TB, the window period is the interval between the first and second round of testing (8 10 weeks). Counting doses Two acceptable regimens both accepted by CDC/ATS/IDSA : 5 days/week DOT dosing, adding missed doses to the end of treatment. 5 days/week DOT dosing but not adding missed doses to the end of treatment. Option is given to allow patients to selfadminister weekend doses. Iowa TB Program Position: Either regimen is effective treatment. However, the Program s preference is for patients receiving daily therapy to have 5 days/week DOT dosing, with patients selfadministering weekend doses (this should be documented as 5 day/week DOT). 13
