An Overview Parasitic and Viral Zoonotic Diseases

Parasitic and viral zoonotic diseases are infections transmitted between animals and humans, posing major public health concerns worldwide. Important parasitic zoonoses include cryptosporidiosis, echinococcosis, giardiasis, liver fluke infection, malaria, taeniasis, toxoplasmosis, and trichinosis, which spread through contaminated food, water, vectors, or animal contact, causing gastrointestinal, hepatic, or systemic illness. Major viral zoonotic diseases include avian influenza, Ebola, Nipah, Marburg, mpox, and rabies, often transmitted through infected animals, bodily fluids, or vectors, leading to severe respiratory, neurological, or hemorrhagic disease. Prevention depends on hygiene, food safety, vaccination, vector control, surveillance, and responsible animal management.
