What is the most common vector of disease transmission?

• A. Ticks
• B. Mosquitoes
• C. Fleas
• D. Lice

Answer: (A)

Mosquitoes are the most common vector of disease transmission. They are widespread, thrive in close contact with humans, and bite multiple hosts, making them highly efficient at spreading a broad range of pathogens. They transmit malaria, dengue, Zika, chikungunya, yellow fever, and other diseases, contributing to a large global burden. While ticks, fleas, and lice can transmit specific diseases, their overall impact is smaller and more regionally limited compared to mosquitoes.
