What is the name for a carrier of infectious agents that transmits disease from one person to another, often insects?

The correct term for a carrier of infectious agents that transmits disease from one person to another, particularly in the context of insects, is indeed "vector." Vectors are organisms, often arthropods like mosquitoes or ticks, that carry pathogens from one host to another, facilitating the spread of diseases such as malaria, dengue fever, and Lyme disease. This role is crucial in the understanding of disease transmission and epidemiology, highlighting the impact that vectors have on public health.

In contrast, laceration refers to a type of wound or injury rather than a method of disease transmission. Prophylaxis is a preventive measure or treatment aimed at preventing disease, often through vaccination or medication, rather than the act of transmitting an infection. Tendinitis refers specifically to the inflammation of a tendon, which is unrelated to the transmission of infectious agents. Understanding these distinctions helps clarify the importance of vectors in the study of infectious diseases.
