Pinworm is the most common
The most common symptom of infection is anal itching, particularly at night, as worms migrate to the host's anal area to lay their eggs.
It is especially active at night or early morning. Rarely, the pinworm is seen on the surface of a stool. The pinworm's secretions are a strong skin irritant and cause the itching.
They don't always cause symptoms, but people often experience itchiness around their bottom or vagina. It can be worse at night and disturb sleep. Read more about the symptoms of threadworms.
So many of us or our family members have experienced this relatively mild though distressing infection. Pinworm is the most common worm infection in North America with up to 50% of some groups of school aged children getting infected.
The eggs pass into the digestive system, where they hatch. About 1 to 2 months later, adult female pinworms lay eggs on the skin right around the anus, which makes the area itchy. Often, this happens at night.

In order to stop the spread of pinworm and possible re-infection, people who are infected should shower every morning to help remove a large amount of the eggs on the skin. Showering is a better method than taking a bath, because showering avoids potentially contaminating the bath water with pinworm eggs.
How is pinworm infection spread? Pinworm infection is spread by the fecal-oral route, that is by the transfer of infective pinworm eggs from the anus to someone's mouth, either directly by hand or indirectly through contaminated clothing, bedding, food, or other articles.

Complete die-off within the tested exposure time range was noted for 70 °C, 75 °C and 80 °C, however treatment at 60 °C and 65 °C allowed for development of a few eggs after incubation. Incubation of heat-treated samples is required when egg damage is not visible, in order to confirm die-off.
Also, threadworm eggs can survive for up to 2 weeks outside the body (on bedding, clothes, etc).
Dipylidium caninum mimicking recurrent enterobius vermicularis (pinworm) infection.
