Some more on Enterobius vermicularis.  The eggs of this worm are laid on 
the skin surrounding the anus, this occurs while sleeping.  The eggs 
quickly contaminate bedding and clothing and because infected children 
may scratch, eggs can often be found under their fingernails.  The eggs 
are very light and the slightest air currents can send the eggs airborne. 
 One becomes infected by inhaling airborne eggs or by placing 
contaminated fingers or contaminated objects in their mouths.  Inhaled 
eggs are swallowed after being caught in mucous which eventually is moved 
to the throat (this is a normal mechanism for the respiratory system to 
rid itself of unwanted particles).  The worms live in the large intestine 
 and have a life span of only about 2 months.  Reinfection is extemely 
common with children easily infecting themselves by scratching then 
putting their finger in their mouths.

There are several drugs which are highly effective (ie vermox) but 
reinfection is a common problem.

To prevent reinfection practice good hygiene in the form of handwashing 
and frequently bathing (showers are preferable to baths) especially in 
the morning  Frequently (daily) change of underwear, bedclothing and 
bedding which are most likely to be contaminated. Towels and the afore 
mentionsed items should be laundered in hot water.  Cut fingernail short 
to lessen the chances of eggs being trapped beneath them.

Infection with pinworms may very well be the worlds most common parasitic 
infection.  From "Diagnostic Medical Parasitology" (Authors - Garcia and 
Bruckner - 1997 - ISBN -1-55581-116-7) "It has been said, "You had this 
infection as a child: You have it now: or you will get it again when you 
have children!".  "Pinworm neurosis" can occur in parents and sometime 
reassurance and counseling is needed - this is a normal event in most 
peoples lives and no negative stigma should be attached to it.
