By observing the number of pinworms escaping, the author noticed that the disease runs cyclically, after a significant escape of pinworms follows an interval when the parasites are excreted in very small numbers, or even not excreted at all. Such intervals correspond to 6-7 weeks, after which the worms start to excrete again. This phenomenon, in the author's opinion, is caused by the development of new generations of the parasite, which takes 5-6 weeks.
