The correct answer is: An organism that transmits a pathogen

In medical terminology, a vector specifically refers to an organism that transmits a pathogen from one host to another. This could include a wide range of entities such as insects, rodents, or even certain forms of blood that carry infectious agents like viruses or bacteria. Examples of vectors include mosquitoes that transmit malaria or ticks that spread Lyme disease. Recognizing the role of vectors is crucial in understanding disease transmission and the importance of vector control in public health. Vectors are often pivotal in the life cycle of pathogens, facilitating their spread and impacting health outcomes significantly. Understanding this definition helps in identifying how diseases are transmitted and the necessary precautions to prevent outbreaks.
