Pin worms are one of those especially creepy parasites that find their way into the system in particularly disgusting ways. I found out all about pin worms when one of our children got them. A child gets pin worms by touching an infected object and then putting his fingers into his mouth. Fortunately, if you are already taking Bromalite, this will serve as a much needed precaution, since you can sometimes still get pin worms even if you try to be careful. As with head lice, getting pin worms serves as a cautionary tale about school children sharing possessions. It also teaches the importance of keeping clean and trim fingernails.
