Liver flukes are parasitic flatworms that primarily infect the liver, gallbladder, and bile ducts of humans and animals. These parasites belong to the class Trematoda, which includes several species known to cause disease in humans. The most common liver flukes affecting humans are Clonorchis sinensis, Opisthorchis viverrini, and Fasciola hepatica. These infections are a significant health issue in certain parts of the world, particularly in Asia.
