The mosquito regulates its ability to cause disease and affect the severity of the disease. Parasite gene expressions can change during transmission which changes the immune response of the host which in this case is a mammal. Pathogenic microorganisms employ diverse transmission mechanisms. This can be direct or indirect contact. In this case, mosquito injects the infection into Jane in the form of a mosquito bite. The mosquito is a vector.
The mosquito played the role of vector, which is an organism that bites and transmits a disease or parasite to the victim, in this case, the victim is Jane. Hope this helps.
