The tapeworm Hymenolepis nana is a parasite that infests the intestine of humans and other animals.
The majority of Hymenolepis nana infections is asymptomatic. When symptoms occur they may include sickness, feeling of faintness, loss of appetite, diarrhoea, and stomach pain.
Transmission mainly occurs via contaminated water and food.
For a successful inactivation of parasites, specific disinfectants effective against parasites are required.
