Watchful waiting may not be appropriate
for family members of a person infected with pinworms. If one member of a
family has a pinworm infection, it is very likely that other members also are
infected. This is very important if a family member is pregnant. A pregnant

of the household may decrease the likelihood of her getting the infection. Some
doctors recommend treating all members of the family to help prevent
reinfection and the spread of infection.
