1. Strongyloides stercoralis Abdirahman Gulaid

2. Definition Human parasitic disease caused by nematode S. Stercoralis. Mostly in tropical, subtropical area and temperate climate. Affect 30-100 million annually. Has two unique life cycle: Free life cycle and Parasitic life cycle.

3. Definition Cause by direct contact with contaminated soil and recreational activities. Children highly affected to bad sanitation. S. stercoralis is a 2 mm long intestinal worm

4. Rhabditiform (L1) larva of Strongyloides stercoralis is about 0.3 mm long. (1 µm = 0.001 mm)

5. Life Cycle

9. Pathology Invasive : Skin Penetration. Pulmonary: During Cycle or Immigration. Intestinal: Tissue Destruction

10. Symptoms and Signs of Hyperinfection  anemia (for example, pale skin)  constipation  cough  diarrhea  eosinophilic pneumonitis (during larvae migration through the lungs)  Nausea  vomiting  weight loss.

11. Symptoms of Immunosuppressed patients (organ transplant) or immunocompromised patients (HIV): Death neurological and pulmonary complications shock.

12. Diagnosis  Stool culture most effective way.  Confusion diagnosis arise day-to-day variability number of juvenile worm.

13. Treatment  Strongyloidiasis is treated with:  Ivermectin.  Tthiabendazole.  No public health strategies for controlling are active at global level.

14. Control Good sanitation with specific care of human waste disposal. Mass treatment of Ivermectin drugs shows some progress but needs further research. Setting global health plan. Wearing permanent shoes. Education Program for community.

15. discussion How many people affected yearly. Is it one of the neglected WHO diseases. How many life cycle does it have. Where it is the main host in human body. What is the name of the drug treat. One of the best way to control.
