Which one of the following is an example of zoonosis disease?

  1. Measles

  2. Diptheria

  3. Leprosy

  4. Rabies
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

A zoonotic disease is a disease that is transmitted from animals to humans. They can be caused by viruses, bacteria, parasites and fungi. Measles is a viral disease in humans. Diptheria is caused by bacterium Corynebacterium diptheriae. Leprosy is chronic infection caused by bacteria Mycobacterium leprae.
Rabies is one such zoonotic disease caused by the rabies virus of the genus Lyssavirus.
Thus, the correct answer is option (D), 'Rabies'.

Dengue is transmitted by

  1. Aedes

  2. Male Anopheles

  3. Female Anopheles

  4. Tsetse fly
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Aedes aegypti, the principal mosquito vector of dengue viruses is an insect closely associated with humans and their dwellings. People not only provide the mosquitoes with blood meals but also water-holding containers in and around the home needed to complete their development. The mosquito lays her eggs on the sides of containers with water and eggs hatch into larvae after a rain or flooding. A larva changes into a pupa in about a week and into a mosquito in two days.

  1. Malaria

  2. Dengue

  3. Sleeping sickness

  4. Kala-azar
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation
  • Dengue fever is a mosquito-borne tropical disease caused by the dengue virus. Dengue is spread by several species of a mosquito of the  Aedes Type, principally A.aegypti.
  • Symptoms typically begin three to fourteen days after infection.[2] This may include a high fever, headache, vomiting, muscle and joint pains, and a characteristic skin rash
  • Arbovirus is an informal name used to refer to any viruses that are transmitted by arthropod vectors. As dengue is transmitted by an arthropod vector(mosquito) its causative organism is called arbovirus. Hence Aedes spreads Dengue'.
  • So,the correct answer is 'Dengue'.
