Why the study?
Does chickenpox infection depress tuberculin reactivity?
Does chickenpox infection depress tuberculin reactivity?
Chickenpox infection transiently depresses tuberculin sensitivity, particularly during the first 6 days of rash.
Chickenpox may transiently suppress tuberculin reactivity in children; hypothesis-generating for TB test interpretation and requires prospective confirmation.
Chickenpox causes tuberculin sensitivity to be depressed in some cases. Such an effect may develop in the incubation period, is most marked during the first 6 days with rash, and rapidly disappears in most cases.
