Threadworms (Strongyloides stercoralis) are tiny intestinal parasites that cause strongyloidiasis. They may not show symptoms or can cause a range of issues, including stomach pain, diarrhea, and in severe cases, malabsorption. Transmission happens when skin comes into contact with contaminated soil. These worms are unique because they can reproduce inside the host, leading to persistent, long-term infections.
They occur worldwide, with higher prevalence in tropical and subtropical regions. In some communities, infection rates can be very high. Most common in warm, moist climates where direct contact with contaminated soil is frequent.
Ivermectin or albendazole are effective treatments. Addressing hygiene and environmental sanitation is crucial for controlling spread.
Wearing shoes and avoiding direct contact with soil that may be contaminated can prevent infection. Improved sanitation and hygiene practices also reduce the risk of spread.
