What does Aedes albopictus transmit?
Aedes albopictus has a role in transmitting dengue virus, chikungunya virus, and filarial nematodes from the genus Dirofilaria.
Why is Aedes aegypti considered a good vector?
Aedes mosquitoes have a high vectorial capacity (effectiveness of virus transmission in nature) for the Dengue Virus (DENV), Chikungunya Virus (CHIKV), Zika Virus (ZIKV) and Yellow Fever virus (YFV) through their behavior and preferred habitats [5] .
What is the vector of the dengue virus?
Through Mosquito Bites Dengue viruses are spread to people through the bites of infected Aedes species mosquitoes (Ae. aegypti or Ae. albopictus). These are the same types of mosquitoes that spread Zika and chikungunya viruses.
What is the primary vector for Zika virus?
Zika virus is transmitted to humans primarily through the bite of an infected Aedes species mosquito (Ae. aegypti and Ae. albopictus). The mosquito vectors typically breed in domestic water-holding containers; they are aggressive daytime biters and feed both indoors and outdoors near dwellings.
Can any mosquitoes carry dengue?
Only the female Aedes aegypti mosquitoes can spread the dengue virus and in fact, these mosquitoes can transfer the infection only when they themselves are infected. So, no need to panic after each mosquito bite.
Is dengue transmitted by saliva?
When taking a blood meal, an infected female mosquito injects its saliva into the human host to prevent the host’s blood from clotting and to ease feeding. This injection of saliva infects the host with the dengue virus.
Is chikungunya a vector borne diseases?
Other viral diseases transmitted by vectors include chikungunya fever, Zika virus fever, yellow fever, West Nile fever, Japanese encephalitis (all transmitted by mosquitoes), tick-borne encephalitis (transmitted by ticks).
What kind of virus does Aedes albopictus carry?
A. albopictus was suspected of being a vector or secondary vector of several viruses, particularly of the viruses that cause dengue fever and dengue hemorrhagic fever (Dengue virus; DENV) [2]. The emergence of dengue hemorrhagic fever in Asia has been attributed to A. aegypti, a mosquito closely related to A. albopictus.
When was Aedes albopictus first reported in the US?
Aedes albopictus was first reported in Europe in 1979 in Albania. In 1985 it was reported in Texas, USA and has since spread northward and eastward, having now been reported in at least 32 US states including Hawaii. This expansion was facilitated by the movement of used tyres along the interstate highways.
When does an Aedes aegypti bite a person?
An Ae. aegypti or Ae. albopictus mosquito bites an infected person during the first week of infection when the virus can be found in the person’s blood. The infected mosquito lives long enough for the virus to multiply and for the mosquito to bite another person.
Where do Aedes aegypti mosquitoes live in the world?
These mosquitoes live in tropical, subtropical, and in some temperate climates. They are the main type of mosquito that spread Zika, dengue, chikungunya, and other viruses. Because Ae. aegypti mosquitoes live near and prefer to feed on people, they are more likely to spread these viruses than other types of mosquitoes.
