What is Filariasis?
- About:
- Filariasis is a parasitic infection caused by microscopic, thread-like worms known as filariae. It is spread by the bite of infected mosquitoes, and it affects millions of people in tropical and subtropical regions worldwide.
- Causes and Transmission:
- Lymphatic filariasis is caused by infection with parasites classified as nematodes (roundworms) of the family Filariodidea.
- There are 3 types of these thread-like filarial worms:
- Wuchereria bancrofti, which is responsible for 90% of the cases,
- Brugia malayi, which causes most of the remainder of the cases,
- Brugia timori, which also causes the disease.
- Symptoms:
- Lymphatic filariasis infection involves asymptomatic, acute, and chronic conditions.
- In chronic conditions, it leads to lymphoedema (tissue swelling) or elephantiasis (skin/tissue thickening) of limbs and hydrocele (scrotal swelling).
- Lymphatic filariasis infection involves asymptomatic, acute, and chronic conditions.
- Treatment:
- The World Health Organization (WHO) recommends three drug treatments to accelerate the global elimination of lymphatic filariasis. The treatment, known as IDA, involves a combination of ivermectin, diethylcarbamazine citrate and albendazole.
- The plan is to administer these drugs for two consecutive years. The life of the adult worm is hardly four years, so it would die a natural death without causing any harm to the person.
