Definition

1. Noun:
   • A parasitic disease caused by thread-like nematode worms (filariae): Filariasis is an infectious disease where parasitic roundworms are transmitted to humans through the bites of infected mosquitoes. The adult worms live in the lymphatic system, blood vessels, or other tissues, often leading to severe swelling and other complications.

Examples of Usage

• Noun:
  • Lymphatic filariasis, also known as elephantiasis, is a major public health problem in many tropical regions.
  • The global program aims to eliminate filariasis through mass drug administration.
  • A blood test can confirm a diagnosis of filariasis by detecting the presence of microfilariae.

Advanced Usage

• "Bancroftian filariasis": The most common form of lymphatic filariasis, caused specifically by the parasite Wuchereria bancrofti.

  • Bancroftian filariasis accounts for about 90% of lymphatic filariasis cases worldwide.

• "Subcutaneous filariasis": A form of the disease where the adult worms reside in the layers under the skin, often caused by Loa loa (the eye worm) or Onchocerca volvulus (causing river blindness).

  • Onchocerciasis is a type of subcutaneous filariasis that can lead to visual impairment.

Variants and Related Words

• Filarial (adj): Pertaining to or caused by filariae.

  • The patient exhibited classic filarial symptoms.

• Microfilaria (n): The microscopic larval stage of the filarial worm, often found circulating in the blood.

  • The microfilariae are typically taken up by mosquitoes during a blood meal.

Synonyms

• Elephantiasis (specifically for the chronic, disfiguring swelling associated with lymphatic filariasis).
• Lymphatic filariasis (the specific clinical term for the disease affecting the lymphatic system).

Related Phrases

• "Mass drug administration for filariasis": A public health strategy to treat entire at-risk populations with anti-filarial medication to interrupt transmission.

  • The success of the elimination campaign depends on high coverage during mass drug administration for filariasis.

• "Filariasis endemic area": A geographic region where the disease is constantly present.

  • Travelers to filariasis endemic areas are advised to take precautions against mosquito bites.
