Evidence of *Trichuris trichiura* eggs has been found in ancient mummies, suggesting its long history of infecting humans. The adult worm was first described in detail in the 18th century. Today, it remains one of the most prevalent soil-transmitted helminth infections and a significant neglected tropical disease globally.
Trichuriasis is transmitted through the **fecal-oral route**. Infection occurs when a person ingests embryonated *Trichuris trichiura* eggs, which are found in soil contaminated with human feces. This typically happens through consuming contaminated food or water, or by placing contaminated hands or objects into the mouth.
