In Enterobius vermicularis infection, specimens for detecting eggs are best collected at what time to maximize yield?

Explanation:
Enterobius eggs are laid on the skin around the anus by female worms during the night. The detection method (tape test) works best when eggs are still present on the perianal skin, which is most likely just after waking up or in the evening before bathing. Collecting at these times maximizes yield because washing, defecation, or daytime activity can remove or dilute eggs. Therefore, the optimal sampling times are in the evening or in the morning before bathing or defecation.
