Pathogenesis. The hookworm and an American hookworm are localised in a thin intestine, mainly in duodenal and lean intestines. Larvas of hookworms get to an organism of the master mainly through a mouth and educe in an intestine without migration. American hookworm larvas usually take root activly through a skin, inpour into vascular capillars, migrate on the big and small circles of a circulation. Having reached lungs, through pneumatic pathes, a larynx and a pharynx they get to an esophagus and an intestine where in 4-5 weeks educe in adults of helminths. Parasitizing in an intestine, helminths eat basically blood, putting to an intestine mucosa fine wounds by chitinous arms of a stomatic capsule. In head and cervical parts there are glands which excrete the special anticoagulants which cause a long bleeding. The intensive invasion, especially at children's and young age, can lead to a delay in physical and mental development, to attrition and a cachexia. Quite often in these cases the invasion comes to an end with a lethal outcome. Lifetime of helminths, possibly, 3-5 years, probably, more longly. The majority of Ancylostoma perishes in 1-2 years after penetration into a body of the human.
I know that this question has been asked before so I thought I'd post an answer. According to the newest issue of the NMSS magazine the Red Cross now accepts blood from those dxed with MS since there is no evidence it is trasmitted via blood. It also says that most medications taken for chronic illnesses won't disqualify a donor. Just thought I'd share.
