Indtoduction - Taenia Solium

9 important questions on Indtoduction - Taenia Solium

What are symtpoms of infection with Taenia Solium?

1. Taeniosis, infection with tapeworm. Abdominal complaints, diarrhea, vomiting, weight loss
2. Cysticersocis, 50-70% asymptomatic. Host reaction to cysts. In muscles of subcutaneous.
3. Neurocysticercosis. Main cause of acquired epilepsy

Which risk factors are present in Zambia?

1. Free roaming pigs with access to human stool
2. No meat control
3. No food safety
4. Quickly fried meat

Also, 60% live in rural area and the pig population has been incerasing

How can you control Teania Solium?

1. Education
2. Sanitation
3. Cooking the meat
4. No free roaming
5. Treatment of people and pigs
  • Higher grades + faster learning
  • Never study anything twice
  • 100% sure, 100% understanding

What are the 3 steps of community led total sanitation?

1. Pre-triggering step (contact with leaders)
2. Triggering step (walk though villagaze, localize& map stool)
3. Post-triggering step (action planning, making latrines)

What were the effects of community led total sanitation?

1. No significant improvement of T solium in pigs
2. More & better latrines, but no OD free status
3. No evidence of impact on health outcomes
4. People were positive about less flies & not seeing poop, also worried that the poop will stay as the pigs don't eat it

Which interventions are aimed toward the final host?

1. MDA (but not everyone infected, defecation after treatment, NCC danger)
2. Health education
3. Sanitation

How can health education be implemented?

1. Increase knowledge so they realize risk behavios, also give explanation
2. Train health staff & training in villages
3. Use vicous worm computer game for both policy makers and people

How can you target the intermediate host, the pigs?

1. No access to human stool (requires costs foor feed and construction + manpower)
2. Treatment (only oxfendazole works, but it takes time for cysts to disappear)
3. Vaccination (works but need 2-3 doses)
4. Meat inspection (tongue palpation low sensitivity, no incentive)
4. Preparation of pork

What were conclusions form the cysti-stop study?

1. In elimination group 0 viable cysts in pig, in control group 25%
2. Reluctance pig owners vaccination
3. Only 20% pigs vaccinated
4. Restock of infected pigs
5. Human movement

So good coverage and high acceptance of interventions. Also significant reduction in pig cysticercosis & taeniasis, and in transmission
