In brief: Yes
The infective stage of this paracite is a cyst that matures after reproduction in the intestineof the symptomatic or asymptomatic host.
The host may be human or animal ( wild or domestic). That material ends up in the water and may pass unseen into the mouth from the contaminated hands or thru ingestion of tainted water. Day care centers/wadeing pools are common risk factors.
