Which type of transmission uses vectors, such as insects?

Vectorborne transmission is a method of disease transmission that specifically involves living organisms, known as vectors, which carry pathogens from one host to another. Insects, such as mosquitoes, fleas, and ticks, are classic examples of vectors. These organisms not only transmit pathogens but often play a crucial role in the life cycle of the pathogen itself. For instance, the malaria parasite must infect a mosquito before it can be transmitted to humans. This method contrasts with other transmission types, such as airborne transmission, which involves the dispersion of pathogens in the air, or contact transmission, which relies on direct or indirect physical contact. Understanding vectorborne transmission is crucial in disease prevention and control strategies, particularly in reducing the populations of vectors and limiting their ability to spread disease.
