Aedes mosquito is a vector for
-
Plague
-
Malaria
-
Filaria
-
Encephalitis and Dengue
Aedes is a genus of mosquitoes originally found in tropical and subtropical zones but now found on all continents except Antarctica. Some species of this genus (like Aedes albopictus and Aedes aegypti) transmit serious diseases, including dengue fever, yellow fever, eastern equine encephalitis and chikungunya. So, the correct answer is option D.
Dengue fever is spread by
-
Anopheles
-
Aedes
-
Culex
-
Musca.
- Dengue fever is spread through the bite of the female mosquito (Aedes aegypti).
- The mosquito becomes infected when it takes the blood of a person infected with the virus. After about one week, the mosquito can then transmit the virus while biting a healthy person.
- Hence Dengue fever is spread by Aedes.
- So, the correct answer is 'Aedes'.
Aedes is vector of
-
Plague
-
Malaria
-
Filaria
-
Encephalitis and Dengue.
- A disease vector is an agent who carries and transmits an infectious pathogen into another living organism.
- Aedes mosquito is known to transmit dengue virus, yellow fever virus, chikungunya virus, Zika virus and Encephalitis(inflammation of the brain).
- It can be recognized by white markings on its legs and a marking in the form of a lyre on the upper surface of its thorax.
- Hence Aedes is a vector of 'Encephalitis and Dengue'.
- So, the correct answer is 'Encephalitis and Dengue'.
Aedes is the carrier of
-
Dengue fever
-
Relapsing fever
-
Malaria
-
None of the above.
Aedes aegypti is vector of
-
Yellow fever
-
Dengue fever
-
Both A and B
-
Japanese encephalitis.
- A disease vector is an agent who carries and transmits an infectious pathogen into another living organism.
- Aedes aegypti is known to transmit dengue virus, yellow fever virus, chikungunya virus, and Zika virus.
- It can be recognized by white markings on its legs and a marking in the form of a lyre on the upper surface of its thorax.
- Hence Aedes aegypti is a vector of Yellow fever and Dengue fever.
- So, the correct is 'Both A and B'.
Aedes aegypti is a vector for
-
Yellow fever
-
Dengue fever
-
Japanese encephalitis
-
Both A and B.
- A disease vector is an agent who carries and transmits an infectious pathogen into another living organism.
- Aedes aegypti is known to transmit dengue virus, yellow fever virus, chikungunya virus, and Zika virus.
- It can be recognized by white markings on its legs and a marking in the form of a lyre on the upper surface of its thorax.
- Hence Aedes aegypti is a vector for yellow fever and Dengue fever.
- So, the correct answer is 'Both A and B'.
