It develops in the body for a long time and affects multiple internal organs.


The mechanism of parasite infection in humans is similar to the process of animal infection. helminth eggs into the soil with feces. Their maturation occurs depending on the temperature of 5-36 day. It was after this period they become infectious, this state is maintained parasite larvae.
