Question: 1 / 400

Which of the following is considered a vector of disease?

Ticks

Flea

The correct answer is ticks, as they are well-known vectors of disease. Vectors are organisms that can carry and transmit pathogens to other living organisms. Ticks can harbor various diseases, such as Lyme disease, Rocky Mountain spotted fever, and anaplasmosis, which they transmit through their bites.

Fleas also act as vectors for disease, primarily through their ability to transmit parasites and bacteria, such as the bubonic plague and tapeworms.

Water and soil can serve as mediums for the transmission of certain pathogens, but they do not function as vectors in the same way that living organisms like ticks and fleas do, which actively carry and spread diseases. Thus, while the other options are relevant to disease transmission, ticks are specifically classified as vectors due to their direct role in spreading infections through their interactions with hosts.
