Parasitic worms are very common globally, affecting about 24% (1.5 billion people) of the world's population, especially in tropical/subtropical areas with poor sanitation, with soil-transmitted worms (like roundworm and hookworm) being the most widespread, although they are less common in developed nations like the U.S. where pinworms and protozoa (like Giardia) are more frequent. While many infections cause few or no symptoms, they can lead to serious health issues like anemia, particularly in children.
Other types of worms may be diagnosed in the laboratory from a fresh stool sample. For example, tapeworms are diagnosed by finding worm segments or worm eggs in a stool sample. Other worms are diagnosed by the presence of eggs, larvae or the parasites themselves in the stool sample.
Parasites and parasitic infections are common. They affect millions of people throughout the entire world. Many people may not notice they have an infection because they have few symptoms.
In Australia, one of the most common human worm parasitic infections is caused by the dwarf tapeworm, a parasite that affects up to 55% of some remote communities. According to official figures, Australia has threadworms, which infect up to 50% of children. What is a parasitic infection?
Approximately one-quarter of the global population is infected with soil-transmitted helminths, intestinal parasitic worms that can cause serious health problems.
Antibody testing shows approximately 14 percent of the U.S. population has been infected by a roundworm species. Most infections occur in people under the age of 20, with children being at the highest risk. Most people have very mild or no symptoms, depending on how many worm eggs someone is exposed to.
About 20% of children will get pinworms. It is more common in school-age children than pre- schoolers. Adults are rarely affected, except for parents of infected children.
Worms are a very common source of illness for both adults and children, so experts recommend that deworming should be done two times a year, or every six months, beginning at the age of two years. Deworming is the process of eliminating intestinal parasites, such as worms, using medication.
Ivermectin is an antiparasitic agent used to treat a variety of infections, both in people and animals. Albendazole is also a broad spectrum antiparasitic used to treat several intestinal parasite infections. Both ivermectin and albendazole are included in WHO's list of essential medicines .
Frequently, healthcare providers do not have sufficient knowledge to clinically identify parasitic infections in any or all of their diagnostic stages. Therefore, healthcare providers make presumptive diagnoses rather than relying on definitive laboratory diagnoses.
10 Warning Signs of Parasitic Infections
Malaria is probably the most prevalent and debilitating parasitic disease afflicting humans. It is normally caused by one of four species of Plasmodium. Infection with Entamoeba histolytica, resulting in amoebic colitis and liver abscesses, is the second leading cause of death resulting from a parasitic infection.
It is equally important for adults to get the appropriate diagnosis and medicine for stomach worms. Regular deworming not only prevents health issues in adults as individuals but it is also a good health practice to safeguard the collective health and overall well-being of communities.
CDC recommends that three or more stool samples, collected on separate days, be examined. This test looks for ova (eggs) or the parasite. Your health care provider may instruct you to put your stool specimens into special containers with preservative fluid.
Some of the most common signs of a parasitic infection include:
Can intestinal worms go away on their own? In some mild cases, the immune system can eliminate parasites without treatment. However, without intervention, many infestations persist and worsen, leading to complications. Therefore, it is essential to actively treat these infections.
If you continue to experience symptoms like stomach cramps and pain, nausea or vomiting, dehydration, weight loss, and digestive problems, including unexplained constipation, diarrhea, or persistent gas even after trying several treatments, you may have a parasite.
Any immune response will eventually deploy mechanisms that are able to control, contain or kill an invader. Thus, a variety of killer cells, phagocytes, reactive oxygen species or antimicrobial peptides are the eventual means by which a parasite is killed by the host.
Pinworms are small white worms about 1/2 inch long and as thin as a thread. They can sometimes be seen in and around the child's bottom (anus) and in bowel movements. These worms live in the intestine. The adult female worm crawls out of the infected person's anus at night and lays her eggs in the surrounding skin.
According to the World Health Organization (WHO), approximately 25% of the world's population has an infection related to an intestinal parasite. In tropical and subtropical areas with limited access to clean water and sanitation, that number is as high as 50%.
❖ Change and wash underwear, nightwear (and bed linen if possible) each day. Avoid shaking clothes and linen as any eggs on them may be wafted into the air and be swallowed. ❖ Also, each day for the same 14 days it is advisable to: Vacuum and dust all household carpets, particularly those where children play.
Intestinal parasites not uncommon
While rates of infection have been falling generally, between 10 and 50 per cent of children carry pinworms. One intestinal nasty, Strongyloides stercoralis, is more common in rural and remote Aboriginal communities than anywhere else in the world.
How are pinworms treated? Your child will need to take an oral (taken by mouth) anti-parasitic medication to kill the worms. They'll take one dose immediately and another dose two weeks later to be sure all the worms are gone.
You can spot threadworms in your poo. They look like pieces of white thread. You might also see them around your child's bottom (anus). The worms usually come out at night while your child is sleeping.
If you scratch the skin around your anus, the eggs get on your fingers and under your nails. These eggs can then be transferred to your mouth. Once swallowed, the eggs travel to your intestines where they grow into worms. Their life cycle then repeats.
