Some viral diseases can be transmitted from person to person, but there are some that need vectors to be transmitted, that is, they need organisms that carry the virus to a person. The only disease cited that needs a vector to be transmitted is chikungunya fever. Alternative B.
Diseases that need a vector to be transmitted are those that are spread through a vehicle, whether biological, such as a mosquito or snail, or mechanical.
Chikungunya fever cannot be transmitted from one human to another, being a disease spread through the bite of the female mosquitoes Aedes aegypti and Aedes albopictus that are infected by the arbovirus Chikungunya. These mosquitoes proliferate in stagnant water and therefore it is necessary to pay greater attention in rainy periods.
