Worms are mainly spread in small bits of poo from people with a worm infection. Some are caught from food. You can get infected by: touching objects or surfaces with worm eggs on them – if someone with worms does not wash their hands.
How do intestinal worms get in you?
You get it by eating infected meat, especially pork, that's raw or undercooked. When a person eats infected meat, stomach acid dissolves cysts in the meat to release worm larvae. The worms go to the intestine, grow up, mate, and lay eggs. After hatching, young worms go through the blood to the muscles.
How are intestinal worms passed?
This type of roundworm spreads through poor hygiene. It often lives in human feces (poop). People catch it through hand-to-mouth contact. If you have a roundworm infection of your intestines (ascariasis), you may not have symptoms.
Are intestinal worms 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.
Can intestinal worms be transmitted through saliva?
Vector-borne transmission of disease can take place when the parasite enters the host through the saliva of the insect during a blood meal (for example, malaria), or from parasites in the feces of the insect that defecates immediately after a blood meal (for example, Chagas disease).
