The eggs are caught under the fingernails, and easily spread to other humans or back to the original host. Eggs can also be inhaled with dust or licked off fingers which have touched dusty surfaces. The most common worm parasite in the modern affluent areas of the world. 30% of US children are estimated to be infected, however infection causes little harm in a healthy human. In Taiwan studies have shown that those infected with pinworm are less likely than uninfected members of the general population to have hay fever (Clinical Experimental Allergy, vol 32, p1029). Intestinal roundworm, Ascaris lumbricoides. Eggs are eaten with contaminated food. Infection is common in some rural areas of the US with up to 60% of the population infected.
