Strongyloidiasis is a parasitic infection caused by the roundworm Strongyloides stercoralis. It is a neglected tropical disease that is uncommon in the United States but prevalent in tropical and subtropical regions, particularly in rural areas and institutional settings. The parasitic worms enter the human body through the skin, making their way into the lungs and intestines, where they mature, reproduce, and cause infection. Strongyloidiasis can be challenging to diagnose as many infected individuals exhibit no symptoms, and standard stool examinations may not always reveal the infection. However, with proper medical treatment, the prognosis for strongyloidiasis is favourable, and full recovery with complete elimination of the parasites is expected. This article will discuss the methods to eliminate Strongyloides stercoralis from the muscles and prevent potential health complications.

Strongyloidiasis is caused by the parasitic roundworm S. stercoralis
Strongyloidiasis is an intestinal parasitic infection caused by the parasitic roundworm S. stercoralis. It is an uncommon infection in the United States, but it is prevalent in tropical and subtropical climates, particularly in rural areas and institutional settings, such as nursing homes. Strongyloidiasis can also be found in parts of the southern United States and Appalachia, and it has been reported during the summer months in temperate areas.
The S. stercoralis roundworm is a type of parasite that infects mainly humans. Humans typically get infected by coming into contact with contaminated soil. The parasite enters the body through the skin and can cause an itchy rash. Once inside the body, the parasite moves into the bloodstream, passing through the heart and into the lungs. From there, it travels up the windpipe into the mouth, where it is swallowed and eventually makes its way into the small intestine.
The S. stercoralis parasite can complete its life cycle inside the human body, allowing it to reinfect the host repeatedly without the need for further exposure to infected sites. This can lead to chronic strongyloidiasis, which can last for years without treatment. While many people infected with S. stercoralis may be asymptomatic, the infection can cause serious illness, especially in individuals with weakened immune systems.
The goal of treating strongyloidiasis is to eliminate the worms. The medication of choice is often a single dose of the antiparasitic drug ivermectin (Stromectol), which kills the worms in the small intestine. Doctors may also prescribe albendazole (taken in two courses, 10 days apart) or thiabendazole (taken twice per day for two to three days). Proper medical treatment for strongyloidiasis typically leads to a full recovery, and the parasites are eliminated.

The parasite enters the body through contaminated soil or water
Strongyloides stercoralis is a parasitic roundworm that infects the human body. It is a soil-transmitted helminth (STH) that is endemic in many parts of the world, particularly in tropical and subtropical climates. Strongyloides can also be found in more temperate climates, including parts of the southern United States, such as Appalachia.
The parasite enters the human body through contaminated soil or water. The filariform larvae in contaminated soil or water penetrate human skin when there is contact with the skin. The larvae can penetrate the skin without the need for a cut or break in the skin. As they move through the skin, they can cause an itchy rash. Once they have entered the body, the larvae move into the bloodstream and pass through the heart, eventually reaching the lungs. In the lungs, the larvae continue their journey up the windpipe and into the mouth, where they are swallowed. The parasites then travel into the stomach and move into the small intestine, where they mature and reproduce. The female parasites embed themselves in the submucosa of the small intestine and produce eggs via parthenogenesis. The eggs hatch and the resulting larvae are passed in the stool, continuing the life cycle of the parasite.
In addition to penetrating the skin, the filariform larvae can also penetrate the intestinal mucosa or the skin of the perianal area, resulting in autoinfection. This allows the larvae to re-infect the host and continue their lifecycle without the need for external exposure to new worms from the soil. The autoinfective cycle can cause chronic strongyloidiasis, which can last for years without treatment. The parasite can also cause hyperinfection syndrome, which is characterised by uncontrolled multiplication and can lead to potentially life-threatening dissemination of larvae, especially in immunocompromised individuals.
To prevent infection by Strongyloides, it is important to practise good personal hygiene, use sanitary facilities, and avoid walking barefoot, especially when travelling to warm or tropical climates.

It can be treated with anthelmintic drugs, antibiotics and antiparasitic medications
Strongyloidiasis is an intestinal parasitic infection caused by the Strongyloides nematode, which can cause a lifelong infection if left untreated. It is important to treat even asymptomatic infections, as hyperinfection syndrome carries a high mortality rate.
Strongyloides infections can be treated with anthelmintic drugs, which target adult worms. These include thiabendazole, albendazole, mebendazole, and ivermectin. However, the effectiveness of anthelmintic agents against larvae is poor, and they are more effective once the infection is established. Ivermectin is the most effective drug and is the drug of choice for acute and chronic strongyloidiasis, hyperinfection syndrome, and disseminated strongyloidiasis. It is a semi-synthetic derivative of avermectin, which binds to nerve and muscle cells, increasing cell membrane permeability, causing paralysis, and resulting in cell death. Albendazole is an alternative to ivermectin, inhibiting tubulin polymerization and decreasing ATP production in the worm, causing energy depletion, immobilization, and death. While mebendazole is also used, it is not recommended due to its limited effectiveness against larvae and its variable efficacy.
Antibiotics are also used to treat Strongyloides infections, particularly in the presence of bacteremia or meningitis. Antibiotic therapy should be provided for 2-4 weeks, according to the results of in vitro testing against the bacterial isolate(s). Supportive treatments, such as intravenous fluids, blood transfusions, and mechanical ventilation, may also be necessary.
Additionally, antiparasitic medications are used to eradicate the infection, reduce morbidity, and prevent complications. Surgical intervention may be required in rare cases of acute abdominal symptoms due to bowel obstruction or infarction.

It is most common in tropical and subtropical climates
Strongyloidiasis is an infection caused by the parasitic roundworm Strongyloides stercoralis. This worm is found mainly in tropical and subtropical climates, but it can also be found in temperate climates. Strongyloides stercoralis is a soil-transmitted nematode, and it is one of the most overlooked helminths among the neglected tropical diseases (NTDs).
The tropical and subtropical climates provide ideal conditions for the transmission of Strongyloides stercoralis. The warm and humid weather in these regions creates an environment that is conducive to the survival and propagation of the parasite. Additionally, the prevalence of contaminated soil and poor sanitation practices in these areas contributes to the spread of the infection.
The risk of infection is also associated with hygiene practices, making children especially vulnerable. In tropical and subtropical countries, the infection rates can be as high as 10% to 40% of the population. In resource-poor countries with ecological and socioeconomic factors that favour the spread of Strongyloides stercoralis, infection rates can even reach up to 60%.
To reduce the risk of infection, it is recommended to practice good personal hygiene, use sanitary facilities, and avoid walking barefoot when traveling to warm or tropical climates. These preventive measures are especially important in areas where Strongyloides stercoralis is endemic, as the parasite thrives in warm and humid environments and can cause serious health issues, especially in individuals with weakened immune systems.
