Lymphatic Filariasis Mosquito Vectors

The lymph system maintains the bodys fluid balance and fights infections. Humans are the exclusive host of infection with W.

Potential factors influencing lymphatic filariasis transmission in hotspot and control areas in Ghana.

Lymphatic filariasis mosquito vectors. This Culex species is highly anthropophilic and so prefers to take its blood meals from humans unlike other Culex vectors that are ornithophilic eg. Culicines Culex quinquefasciatus are the primary vectors in urban areas in eastern and south-ern parts of Africa Pederson 2008. Wuchereria bancrofti Brugia malayi and Brugia timori 1 2.

Lymphatic filariasis LF is a parasitic infection that is spread by mosquitos infected with worm larvae. Lymphatic filariasis is spread from person to person by mosquitoes. The disease was targeted for global elimination by 2020 using repeated community-wide mass drug administration MDA distributed in endemic areas.

Adult worms live in the host lymphatic system for years causing lymphatic dysfunction. More recently Mansonia mosquitoes have been incrimi-nated as potential vectors in rural Africa as well Ughasi et al 2012. It currently is a significant health problem in tropical Africa Asia and the Indian subcontinent many islands of the western and southern Pacific and focal areas of Latin America.

The adult worms only live in the human lymph system. It is estimated that one billion people are at risk of infection and 120 million are affected by LF. A wide range of mosquitoes can transmit the parasite depending on the geographic area.

Lymphatic filariasis can be transmitted in any region of the world where the appropriate mosquito vector breeds. Culex quiquefasciatus is the most important Culex mosquito vector for lymphatic filariasis. It is estimated that one billion people are at risk of infection and 120 million are affected by LF.

90 of infections are caused by Wuchereria bancrofti and the remainder by Brugia spp. Lymphatic filariasis and malaria are endemic in Dar es Salaam and partially share common vectors but no synergy exists between their control programs. WHO works with partners to provide education and improve awareness so that people know how to protect themselves and their communities from mosquitoes ticks bugs flies and other vectors.

Mosquitoes taking a blood meal ingest microfilaria larval stage which are present in the blood. A growing body of evidence suggests that climate change will influence the spread of parasitic diseases and their vectors. In Africa the most common vector is Anopheles and in the Americas it is Culex quinquefasciatus.

Aedes and Mansonia can transmit the infection in the Pacific and in Asia. Gambiae sl which serves as the principal vector of lymphatic filariasis in Ghana was the most abundant mosquito species sampled in hotspot and control districts in both the Western and Upper East regions. Lymphatic filariasis LF is the second most common vector-borne parasitic disease after malaria and is found in over 83 tropical and subtropical countries 1.

Vector-borne diseases are illnesses caused by pathogens and parasites in human populations. Public of Korea lymphatic filariasis was prevalent in the in-land areas of Gyeongsangbuk-do doprovince and coastal and southern areas of Jeollanam-do and Jeju-do. Vectors of Lymphatic Filariasis.

The importance of vectors Infect Dis Poverty. Lymphatic filariasis LF is caused by infection with threadlike worms called nematodes of the family Filarioidea. Lymphatic filariasis LF is the second most common vector-borne parasitic disease after malaria and is found in over 83 tropical and subtropical countries.

Lymphatic filariasis considered globally as a neglected tropical disease NTD is a parasitic disease caused by microscopic thread-like worms. However the prevalence of filariasis has decreased sharply due to medical treatments of microfilaria-positive patients and increased use of mosquito nets 1-5. Lymphatic filariasis LF is a mosquito-borne parasitic infection which is caused by three species of filarial worms.

It can damage the human lymphatic system resulting in disabling complications including lymphoedema and hydrocele 1. Lymphatic filariasis is a mosquito-transmitted nematode parasite infection. Lymphatic filariasis LF is a chronic nematode infection transmitted by mosquitoes and in sub-Saharan Africa it is caused by Wuchereria bancrofti.

In the mosquito ingested microfilaria penetrate the stomach wall develop in the thoracic muscles and eventually migrate to the proboscis. The Global Programme to Eliminate Lymphatic Filariasis GPELF was launched in 2000. The mosquito becomes infective about 12-14 days following a blood meal.

Several factors will affect the global prevalence of LF in the future.
