Context: India has launched a nationwide Mass Drug Administration (MDA) campaign covering 111 endemic districts across 13 states, with the goal of eliminating Lymphatic Filariasis (LF) by 2027.

About Lymphatic Filariasis:

• What is Lymphatic Filariasis? Lymphatic Filariasis (LF), also called Elephantiasis, is a parasitic disease caused by filarial worms that infect the human lymphatic system, leading to severe swelling and disability.

• India’s Status:

• India is among the highest-burden countries for LF, contributing significantly to the global caseload. Bihar, Uttar Pradesh, and Odisha are among the states with the highest number of LF cases The government aims to eliminate LF by 2027 through mass drug administration, morbidity management, and vector control strategies.

• Causes and Transmission:

• Caused by Wuchereria bancrofti (most common), Brugia malayi, and Brugia timori parasites. Transmitted through mosquito bites (Anopheles, Culex, Aedes species). Requires repeated mosquito bites over months or years for infection to establish.

• Symptoms:

• Asymptomatic in early stages but leads to chronic lymphatic damage over time. Common symptoms: Lymphedema: Swelling of arms, legs, breasts, or genitals. Elephantiasis: Thickening of the skin and severe swelling. Hydrocele: Swelling of the scrotum (in males). Recurrent infections due to weakened immunity.

• Prevention and Treatment

• Mass Drug Administration (MDA): Annual distribution of anti-filarial drugs (Diethylcarbamazine + Albendazole). Triple Drug Therapy in select districts to accelerate LF elimination efforts. Triple Drug Therapy include diethylcarbamazine (DEC) + Albendazole + Ivermectin. Morbidity Management & Disability Prevention (MMDP): Ensuring access to care for affected individuals. Surgical intervention: Hydrocelectomy under Ayushman Bharat PM-JAY scheme. Vector Control: Use of mosquito nets, insecticides, and community awareness.
