Where do flukes come from?

The causative agent of flukes is a parasite that lives in the digestive system of fish and other aquatic creatures. The parasite is passed from host to host through the consumption of raw or undercooked infected fish.

The parasite can also be passed through contact with contaminated water, mud, or feces. Once inside the human body, the parasite travels through the bloodstream to the liver and other organs.

The parasite produces a toxin that damages the liver, causing jaundice and death in the host. The parasite can also cause other health problems, including intestinal blockages and inflammation of the pancreas.

In some cases, the parasite can migrate to other parts of the body, such as the lungs, where it can cause serious infection.

There is no specific treatment for flukes, and the only way to prevent them is to avoid exposure to the parasite. However, people who are infected with the parasite generally have no symptoms until the parasite has damaged the liver to a significant degree.
