How common are roundworms? Hundreds of millions of people around the world are infected with roundworms at any given time. But many of these parasites are uncommon in the United States. Americans may come into contact with them when traveling to certain countries.
You cannot get roundworms by simply cuddling your dog or being around them, but there is a risk if you are in contact with their poop. This is why roundworms are most often spread to children, as they are most likely to be playing in potentially infected soil.
Forty-six million people—14 percent of the US—have toxocariasis, although the CDC says true numbers are higher because people rarely connect eventual blindness with roundworms slithering undetected through the body.
Some roundworm infections can last a long time, and there are many possible complications. People living in areas where roundworm infections are common may become infected more than once. Fortunately, most roundworm infections can be treated with antiparasitic medications.
Roundworms do pose a significant risk to humans. Contact with contaminated soil or dog feces can result in human ingestion and infection. Roundworm eggs may accumulate in significant numbers in the soil where pets deposit feces. Once infected, the worms can cause eye, lung, heart and neurologic signs in people.
Roundworm infections usually happen when soil, sand, or plants that have been contaminated with infected animal feces are accidentally put in the mouth and ingested. Hookworm infections happen when larvae penetrate the skin. This usually happens when people sit or walk on contaminated soil or sand with bare feet.
Infections are very rare in Australia and New Zealand, but if you suspect your child may have contracted one, it is advisable to seek medical attention for further treatment and advice. The most common way of catching roundworms is through contaminated soil1.
Roundworm infection is the most common type of worm infection in the world. It is rare in the U.S. Roundworm eggs live in soil that is contaminated by feces. The eggs can get into the body through the mouth.
It takes two to four weeks for the eggs to become infectious. A new host is infected by ingesting the eggs. The eggs hatch, releasing larvae that penetrate the walls of the small intestine and enter the bloodstream. The larvae can travel to organs throughout the body from the blood.
Have a red, itchy rash on your skin. Have stomach problems that last longer than two weeks — such as diarrhea or a stomachache. Have unexplained weight loss. See a worm or piece of a worm in your poop.
Thanks in part to modern plumbing, people in the industrialized world have now lost almost all of their worms, with the exception of occasional pinworms in some children. Intestinal worms are properly called “helminths,” which most dictionaries will tell you are parasites.
A person with intestinal worms may not have any symptoms, but threadworms (Enterobius vermicularis), the most common worm infection in Australia, often do cause symptoms. A person with threadworms (also known as pinworms) may have an itchy bottom or redness and scratch marks around the bottom.
Can you get roundworms from your dog licking you? No, this is very unlikely. Humans become infected with roundworm through accidental ingestion of roundworm eggs from a contaminated environment (e.g. sandpits, parks, playgrounds).
Fortunately, most of it doesn't make us sick, but some can. Parasites like hookworm, roundworm, and giardia can be passed from dog to human through licking.
Ascaris lumbricoides is a nematode, or roundworm, that parasitizes the human gastrointestinal tract. Worldwide, ascariasis is among the most common helminthic human infections with an estimated 800 million to 1.2 billion people infected, and it causes more than 60,000 deaths annually [4, 5].
Roundworms are not particularly harmful to adult cats, but large numbers may cause life-threatening problems in kittens and debilitated older cats. In kittens, common clinical signs include a pot-bellied appearance, abdominal discomfort, depressed appetite, dull coat, vomiting, diarrhea, or poor growth.
The best way to diagnose this infection is to do a tape test. The best time to do this is in the morning before bathing, because pinworms lay their eggs at night. Steps for the test are: Firmly press the sticky side of a 1-inch (2.5 centimeters) strip of cellophane tape over the anal area for a few seconds.
When they reach the intestine they develop into adult worms. The life cycle can take 2–3 months, and adult worms can live for 1–2 years. A female may produce approximately 200,000 eggs per day. The eggs are then passed in the faeces of the infected person.
There are many worms worldwide that can infest the bowels of people. Most of them are not a problem in Australia because of our climate and good standard of sanitation. Worms causing infection in people are parasites that live and breed mostly in the bowel (intestine).
Take the correct dewormer
When infected with worms, it should be dewormed periodically, for adults and children over 2 years old should be dewormed 2 to 3 times a year, ie every 4 to 6 months.
Deworming is not always necessary, but is recommended for children who live in endemic areas once a year when the prevalence of soil-transmitted parasitic worms in the community is over 20% and twice a year when the prevalence of soil-transmitted parasitic worms in the community is 50%.
You can get infected by: touching objects or surfaces with worm eggs on them – if someone with worms does not wash their hands. touching soil or swallowing water or food with worm eggs in it – mainly a risk in parts of the world without modern toilets or sewage systems.
Intestinal worms are common parasites of dogs but luckily it is rare for people to develop illness from worms that affect dogs. If you are concerned about your health and any symptoms that develop it's always best to consult your doctor.
As the worms come out, they may be alive, but will die shortly afterwards.
