Hookworm 



ALTERNATE HOSTS OF PARASITIC WORMS 



The complex life history of the parasitic liver fluke was the first one understood to 

 include alternation of hosts and of distinct generations. Tapeworm is transmitted to 

 the human host by infested meat that has not been cooked enough to kill the worms 

 in the resting stage. Hookworm can be prevented by suitable sanitation, wearing 

 shoes and avoiding contact with the soil
