In which two are intermediate hosts and one definitive host.
1. Firstly an infected host release eggs into the water by means of infected faeces. These eggs are then taken up by snails (which are the first intermediate host) where the eggs complete their gestation period and hatch to form worms.

First intermediate host: Snail
Second Intermediate host: Fish
Definitive Host: Human beings
