This course of is known as extrinsic incubation, which almost lasts 1–3 weeks in mosquitoes. An infection of the salivary gland makes the mosquito competent sufficient to proceed the chain of transmission by infecting a vertebrate throughout a subsequent blood meal. The distributions of those mosquito borne illnesses are ruled primarily by elements like presence of their reservoir hosts and vectors in that space and areas like city or rural settings. Unusual mosquito-borne illnesses like Yellow fever, Zika virus, Japanese Encephalitis, amongst others, might be divided into 4 classes. Viruses able to inflicting human illnesses might be grouped into 4 classes:
1. Arthritis and Rash

3. Fever and Myalgia
4. Viral Hemorrhagic Fever
