A parasitic and infectious tropical disease, that is caused by thread-like filarial nematode worms in the superfamily Filarioidea.
A disease caused by parasitic worms.
A chronic disease caused by a filariae, a nematode.
A tropical disease caused by parasitic threadworms in the lymph system, transmitted by mosquito bites.
Disease, largely of the tropics, caused by filariae (long, threadlike worms) that enter the body through mosquito bites and infest primarily lymph glands and vessels. Symptoms include blockage of the lymph vessels and resultant swelling and pain in the limb distal to the blockage, which, over many years, may lead to elephantiasis. Treatment is by anthelmintics.
A tropical disease caused by the parasitic worm Filaria, whose larvae are carried from one person to another by mosquitoes, mites, or flies. Once inside the human body, the grown worms live in the tissues of the lymphatic system, where they cause swelling, inflammation, and pain. The infection may enormously increase the size of a body part, such as an arm or leg.
A parasitic disease caused by microscopic, threadlike worms that live in the human lymph system. Filariasis, also known as lymphatic filariasis, is found in the tropics and subtropics, particularly central and western Africa. It is spread from an infected person via mosquito bites. The microscopic worms circulating in the infected person’s blood enter and infect the mosquito when the insect feeds on the person’s blood. When the infected mosquito bites another person, the microscopic worms pass through the skin and travel to the lymph vessels, where they grow into adults, subsequently mate, and release millions of microscopic worms into the blood.
A disease, common in the tropics and subtropics, caused by the presence in the lymph vessels of the parasitic nematode worms Wuchereria bancrofti and Brugia malayi. The worms, transmitted to man by various mosquitoes (including Aedes, Culex, Anopheles, and Mansonia), bring about inflammation and eventual blocking of lymph vessels, which causes the surrounding tissues to swell. The rupture of urinary lymphatics may lead to the presence of chyle in the urine. Filariasis is treated with the drug diethylcarbamazine.
The term used to describe several conditions caused by one or other of the nematode filariae (worms); these include Wuchereria bancrofti, Brugia malayi, Onchocerca volvulus, Loa loa, Dracunculus medinensis (dracontiasis or guinea-worm disease), Mansonella perstans, etc.
Parasitic infection with any of the slender worms of the genus Brugia or Wuchereria.
A tropical disease triggered by the presence of worms residing within the lymph channels.
A collection of tropical illnesses is brought about by different types of parasitic worms or their young, which are transferred to humans through insect bites. Female adult worms, whose length may range anywhere from 2 to 50 cm, produce numerous thousands of these immature worms. These larvae travel around the body via the bloodstream. Insects that feed on blood, predominantly certain mosquito species, consume the larvae when they feed on blood from infected individuals, and then transmit them to others through their bites.
Filariasis is commonly found in regions like tropical Africa, Indonesia, the South Pacific, coastal parts of Asia, southern Arabia, Mexico, and Guatemala.
Certain types of worms reside in the lymphatic vessels. Early indicators of the disease include swollen lymph nodes and recurring fever. The inflammation of the lymph vessels leads to localized edema, a condition characterized by fluid buildup in the tissues, causing swelling. With recurrent infections, the impacted area, often a limb or the scrotum, greatly enlarges. Furthermore, the skin turns thick, rough, and cracked, leading to a condition known as elephantiasis.
The young of another kind of worm infiltrate the eye, leading to blindness, a condition also known as onchocerciasis. Another kind of worm’s larvae, occasionally observable and perceptible moving under the skin, lead to loiasis. This condition is defined by irritating and sometimes painful swelling areas, known as Calabar swellings.
Confirmation of a filariasis diagnosis is achieved through a microscopic analysis of the blood. The infection is typically treated with anthelmintic medications such as diethylcarbamazine or ivermectin. However, these drugs may induce certain side effects including fever, nausea, muscle aches, and intensified itching.
The medication diethylcarbamazine can be administered as a preventative measure. Furthermore, employing insecticides and wearing protective attire can provide effective defense against insect bites.
A condition where filarial parasites infiltrate the lymphatic channels, leading to inflammation, tissue scarring, and blockage. This results in significant swelling in the affected area and can cause elephantiasis.
