## Slide 1: Elephantiasis Overview
- Lymphatic Filariasis is a Neglected Tropical Disease caused by parasitic worms.
- Technical report by the Biology Infectious Disease Unit.

## Slide 2: Disease Names
- Common Name: Elephantiasis (from Greek 'elephas' for thick, rough skin).
- Scientific Name: Lymphatic Filariasis; ICD-10 Code: B74.0.

## Slide 3: The Pathogen (Wuchereria bancrofti)
- Primary parasite: Wuchereria bancrofti (90% of cases).
- Type: Parasitic Nematode (Roundworm).
- Size: Females (60–100 mm) are 3x larger than males (40 mm).

## Slide 4: Pathogen Structure
- Adult worms can live coiled inside human lymphatic vessels for up to 7 years.

## Slide 5: Historical Timeline
- 1878: Patrick Manson proves mosquitoes transmit the parasite (first proof of insect-disease transmission).
- 1947: DEC treatment developed.
- 2024: 21 countries have achieved elimination status.

## Slide 6: Transmission Cycle
- Spread by mosquito bites (Culex, Anopheles, Aedes species).
- Not spread by casual person-to-person contact.

## Slide 7: Symptoms & Incubation
- Incubation: 6–12 months.
- Acute Stage: Lymphangitis, fever, and swollen nodes.
- Chronic Stage: Lymphedema, Elephantiasis, and Hydrocele.

## Slide 8: Risk Factors & Complications
- Risks: Living in endemic regions (Africa, Asia, Pacific) and high mosquito exposure.
- Complications: Permanent disability and secondary bacterial infections.

## Slide 9: Treatment & Management
- Drugs: Diethylcarbamazine (DEC), Ivermectin, and Albendazole.
- WHO Triple Drug Therapy (IDA) is the most effective regimen.

## Slide 10: Vaccination & Control
- No vaccine exists; prevention relies on Mass Drug Administration (MDA) and mosquito control.
- 69% reduction in global burden achieved through GPELF.

## Slide 11: Epidemiology
- ~57 million people infected globally (2021 data).
- 61% of cases are in South Asia.
- 10+ billion treatments delivered since 2000.

## Slide 12: Pathogen Images
- Visual comparison of healthy legs vs. severe lymphedema.
- Microscopic views of microfilaria.

## Slide 13: Key Takeaways
- Elephantiasis is preventable, treatable, and eliminatable with global commitment.
