## What is Elephantiasis?
* Also known as Lymphatic Filariasis (LF).
* Caused by parasitic nematode worms, primarily *Wuchereria bancrofti* (90% of cases).
* Transmitted through the bites of infected mosquitoes (*Culex*, *Aedes*, *Anopheles*).
* Progression stages: Asymptomatic to Acute to Chronic.

## Potential Complications
* **Lymphoedema:** Swelling of limbs, breasts, and genitals.
* **Hydrocele:** Scrotal swelling affecting approximately 25 million men.
* **Tropical Pulmonary Eosinophilia:** Respiratory distress and elevated white blood cell counts.
* **Psychosocial Impact:** Significant social stigma, depression, and poverty cycles.

## Treatment & Management
* **Drug Therapies:** Diethylcarbamazine (DEC) at 6 mg/kg/day, Ivermectin, Albendazole, and Doxycycline.
* **Physical Management:** Complex Decongestive Physiotherapy (CDP), limb elevation, and hygiene routines.
* **Surgery:** Hydrocelectomy for managing hydrocele.

## Global Control Programs
* **Mass Drug Administration (MDA):** WHO-recommended annual drug regimens (DEC + Albendazole, or Triple Therapy IDA).
* **Vector Control:** Use of insecticide-treated bed nets and indoor residual spraying.
* **Vaccine Status:** No licensed human vaccine exists, but candidates show ~90% protection in animal models.

## Epidemiology & Disease Burden
* **Risk:** 657 million people in 39 countries remain at risk as of 2023.
* **Infections:** 51 million currently infected; 40 million live with chronic manifestations.
* **Progress:** 74% decline in prevalence since the year 2000.
* **Geography:** High prevalence in Asia, Sub-Saharan Africa, and parts of South America.
