Are intestinal parasites in humans contagious?
Intestinal parasites are contagious to other animals and humans. Because they primarily inhabit the GI tract, larvae, or eggs, are passed in the feces. The infective larvae then inhabit the soil around the feces, leaving other dogs, and children, vulnerable to accidental ingestion and subsequent infection.
How are parasites spread from person to person?
Parasitic infections can be spread in a number of ways. For example, protozoa and helminths can be spread through contaminated water, food, waste, soil, and blood. Some can be passed through sexual contact. Some parasites are spread by insects that act as a vector, or carrier, of the disease.
How are most intestinal parasites transmitted?
Parasites can get into the intestines by going through the mouth from uncooked or unwashed food, contaminated water or hands, or by skin contact with larva infected soil; they can also be transferred by the sexual act of anilingus in some cases.
