Q
Transmission and life cycle
A
Eggs are passed in the stool and under favorable conditions, larvae hatch and become free living in the soil. After a period of time they become infective.
Larvae penetrate the skin of the host mostly through their feet. End up in circulation and go to the lungs.
Coughed up, swallowed and end up in intestines. Here the larvae mature into adult worms and attach to the intestine wall resulting in host blood loss.
The adult worms replicate sexually and produce eggs which are excreted through feces.
