Which disease is caused by Culex mosquito?
Culex. Culex, a large group of mosquitoes also known as common house mosquitoes, are the principal vectors that spread the viruses that cause West Nile fever, St. Louis encephalitis, and Japanese encephalitis, as well as viral diseases of birds and horses.
What are arthropod borne diseases?
What are arboviral diseases? Arboviral disease is a general term used to describe infections caused by a group of viruses spread to people by the bite of infected arthropods (insects) such as mosquitoes and ticks.
What is the vector for chikungunya disease?
Aedes mosquitoes transmit chikungunya virus to people. These types of mosquitoes are found throughout much of the world. Chikungunya virus is transmitted to people through mosquito bites.
How do arthropods spread disease?
Arthropods will transmit diseases via their ability to function as hematophagous vectors which is characterized as their ability to feed on blood at some or all stages of their life cycles. Arthropod vectors include mosquitoes, fleas, sand flies, lice, fleas, ticks and mites.
Which bacteria is transmitted by arthropods?
Anaplasma phagocytophilum, marginatum; Bartonella henselae; Borrelia burgdorferi, afzelii, garinii; Coxiella burnetii; Ehrlichia chaffeensis; Francisella tularensis; Rickettsia prowAZekii, akari, rickettsii and Yersinia pestis are also known as arbobacteria.
What causes chikungunya virus?
Chikungunya is a viral disease transmitted to humans by infected mosquitoes. It is caused by the chikungunya virus (CHIKV). A CHIKV infection causes fever and severe joint pain.
Does arthropods affect human directly?
Arthropods directly affect humans via stings, bites, myia- sis, and other exposure. Painful reac- tions from stings are primarily caused by pharmacological agents contained in the venom. Most bite reactions (except possibly venomous spider bites) are the immune system’s response to salivary secretions.
Which virus is arthropod borne?
The term arbovirus is a portmanteau word (arthropod-borne virus). Tibovirus (tick-borne virus) is sometimes used to more specifically describe viruses transmitted by ticks, a superorder within the arthropods….Arbovirus.

What is Chagas disease?
Related Pages. Chagas disease is named after the Brazilian physician Carlos Chagas, who discovered the disease in 1909. It is caused by the parasite Trypanosoma cruzi, which is transmitted to animals and people by insect vectors and is found only in the Americas (mainly, in rural areas of Latin America where poverty is widespread).
What factors affect the severity and course of Chagas disease?
The severity and course of an individual infection can vary based on a number of factors, including the age at which a person became infected, the way in which a person acquired the infection, or the particular strain of the T. cruzi parasite. There are two phases of Chagas disease: the acute phase and the chronic phase.
What research is being done to treat Chagas disease?
Another research area is the use of biomarkers to predict the progression of chronic Chagas disease. Serum levels of tumor necrosis factor alpha, brain and atrial natriuretic peptide, and angiotensin-converting enzyme 2, markers of heart damage and inflammation, have been found to correlate with the severity of Chagas cardiomyopathy.
What happens if Chagas is left untreated?
Also called American trypanosomiasis, Chagas disease can infect anyone. Left untreated, Chagas disease later can cause serious heart and digestive problems. Treatment of Chagas disease focuses on killing the parasite in acute infection and managing signs and symptoms in later stages.
