Step-by-step explanation:
Pinworm eggs can survive in indoor environments for up to two to three weeks.
Pinworms, also known as Enterobius vermicularis, are tiny nematodes that cause enterobiasis. The adult female worms lay eggs around the anus, which can easily contaminate surfaces and objects in indoor environments. These eggs can survive for a significant period of time, posing a risk of reinfection if not properly cleaned and disinfected.
To prevent the spread of pinworms, it is important to practice good hygiene, such as regular handwashing and thorough cleaning of living spaces.
