filarial worms - HEALTHIES
Filarial worms are a type of microscopic parasitic worm. They mainly spread through insect bites. Symptoms from filarial worm infections can be minor (e.g., itching or swelling) but may be severe (e.g., blindness).
Understanding the Context
There are antiparasitic drugs that can treat filarial worm infections. Explore the complex world of filarial worms, understanding their impact on health, how they spread, and strategies for control. Filarial worms are thread-like parasitic roundworms, known scientifically as nematodes, responsible for a group of infectious diseases collectively called filariasis. Filarial worms are roundworms.

Key Insights
A main difference between filarial worms and other roundworms is that they are transmitted to people via the bites of infected insects, such as blackflies, deerflies, and mosquitoes. Filarioidea are a superfamily of threadlike, parasitic nematodes (worms), with numerous families, genera, and species. Their definitive hosts are vertebrates, but only a few filarial species infect humans. Threadlike adult filarial worms reside in lymphatic or subcutaneous tissues. Adult filarial worms commonly cause subclinical lymphatic dilatation and dysfunction.

Blood smears and serologic tests are typically used for diagnosis. Lymphatic filariasis can be caused by three species of mosquito-borne filarial nematodes: Wuchereria bancrofti, Brugia malayi, and B. timori. You get elephantiasis through tiny parasitic worms (filarial worms) that infect your lymphatic system. These parasites block your lymphatic capillaries and cause fluid (lymph) to accumulate. The Filarioidea are a superfamily of highly specialised parasitic nematodes.
[2][1] Species within this superfamily are known as filarial worms or filariae (singular filaria).
