Aedes mosquito is a vector for

  1. Plague

  2. Malaria

  3. Filaria

  4. Encephalitis and Dengue
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

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

  1. Anopheles

  2. Aedes

  3. Culex

  4. Musca.
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation
  • 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

  1. Plague

  2. Malaria

  3. Filaria

  4. Encephalitis and Dengue.
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation
  • 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

  1. Dengue fever

  2. Relapsing fever

  3. Malaria

  4. None of the above.
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
The dengue virus is transmitted to humans via the bite of an infected mosquito. Only a few mosquito species are vectors for the dengue virus. The dengue virus is carried and spread by mosquitoes in the genus Aedes, which includes a number of mosquito species. Of these species, the primary vector of the dengue virus is the species Aedes aegypti.

So, the correct answer is 'Dengue fever'.
