What are parasitic helminths?

Parasitic helminths are characterized as multicellular organisms that belong to the group of worms which can infect human hosts. These helminths may include flatworms (such as tapeworms and flukes) and roundworms (such as nematodes). As parasites, they thrive by living in or on a host organism, drawing nutrients from the host and often causing a range of health issues.

Understanding that parasitic helminths are multicellular—and distinct from single-celled organisms or viruses—is crucial. They exhibit complex life cycles and can cause significant morbidity in humans and other animals, making their study vital in the field of environmental health. The impact of these parasites on public health serves as a reminder of the importance of sanitation, hygiene, and awareness in preventing infestations.
