Document Summary
Helminths are the biggest infectious burden on our species. Worm infections are most serious in tropical countries: 4,000,000,000 people have one or more intestinal worm infection, 400,000,000 have worms in blood, liver, lung, or other tissues, night soil, guinea worm disease. Helminths can vary in size from almost invisible to the naked eye, to >1m (over 3 ft. ) in length. The worm can break off leading to infections. Since the body encapsulates the worm to prevent it from going elsewhere in the body, if the sack is perforated there is a very high chance of death. Similar to viruses minus the genetic material. Assumed that they are like genetic mutations. Can be passed down from mother to child: they appear to disrupt the normative formation and function of, in brain tissue, they are protected from the immune system by the proteins blood-brain barrier (bbb)
