The eggs can survive for several days in the right conditions. Period of communicability of pinworm (threadworm) infectionĬommunicability continues as long as the eggs are being discharged onto the perianal area. They can also be transmitted indirectly through bedding, clothing, food or other articles. Pinworms are transmitted by direct transfer of infected eggs by hand from the anus to the mouth of the same or another person. Mode of transmission of pinworm (threadworm) Pinworms of other animals are not transmissible to humans. Pinworm infections predominantly affect paediatric populations, in which the prevalence is reported to be 10–50 per cent in some groups. Less attention is paid to the pinworm in tropical regions, presumably because of the prevalence of more important parasites. These infections are found worldwide and affect all socioeconomic groups. The pinworm is the most common helminth parasite of temperate regions. Public health significance and occurrence of pinworm (threadworm) infection A long, thin and sharply pointed tail distinguishes the female worm. Male and female pinworms vary in size, ranging between 2 mm and 13 mm in length and up to 0.5 mm wide, and are yellowish white. The eggs are fully embryonated and are infective within a few hours of being deposited. The lifecycle requires 2–6 weeks to complete. Incubation period of pinworm (threadworm) Microscopy on faeces can be conducted, although finding eggs is exceptional. This is best done in the morning before bathing, as the worms migrate during resting periods. Applying clear sticky tape to the perianal skin and examining it for eggs is the best way to make the diagnosis. The diagnosis should be suspected in children with a perianal itch, and is confirmed by detection of the pinworms’ characteristic eggs. Rarer clinical manifestations include salpingitis, pelvic pain and the formation of granulomas in the peritoneal cavity. Pinworms or their eggs have occasionally been detected at other sites, such as the liver and lung. In children, the pinworm can cause vulvovaginitis during its migration from the anus. Sometimes, secondary infection of the scratched skin occurs. The migration of the female worm from the rectum and then the anus to lay eggs on the perianal skin during the night can lead to perianal pruritus or disturbed sleep or irritability. In the majority of children and adults, infection is asymptomatic.
