We should not allow mosquitoes to breed in our surroundings because they
(a) multiply very fast and cause pollution
(b) are vectors for many diseases
(c) bite and cause skin diseases
(d) are not important insects
Correct Answer: (b) are vectors for many diseases
Explanation:
Vector-borne diseases are caused by the transmission of an infection to humans and other animals by blood-feeding anthropods such as mosquitoes, ticks, and fleas.
For example, Mosquitos are the vector of Chikungunya disease caused by Chikungunya virus (CHIKV), Dengue caused by Dengue virus (DENV), Zika fever caused by Zika virus, and Malaria caused by Plasmodium. Vectors are the anthropods that act as a host for viruses.
Humans cannot be referred to as vectors but the carriers of common infectious diseases such as typhoid, HIV, C. difficile, influenzas, cholera, tuberculosis, and COVID-19.
