trypanosome — parasitic disease *Trypanosoma brucei* in a blood smear (Giemsa-stained light photomicrograph).

In the context of the parasitic disease known as ascariasis, humans become infected with Ascaris lumbricoides through the ingestion of fertilized eggs.1

These eggs typically enter the body when a person consumes food or soil that has been contaminated with human feces containing the parasite. Once ingested, the eggs travel to the small intestine, where the larvae are released to begin their migration through the body.1

To prevent this infection, it is essential to practice proper sanitation, such as the hygienic disposal of human excreta, as well as thorough hand-washing before handling food and the careful washing or cooking of raw vegetables.1
