Diseases are abnormal conditions of the body. Different reasons amount to disease in the human body.
Also, there are some insects that transmit some peculiar diseases to the body. Generally, invertebrates are very common vectors of disease.
They are vectors because they are carriers of disease-causing agents. Also, a vector is an organism which spreads disease from one host to another.
Insects such as mosquitoes, lice, fleas, bed bugs, ticks, are vectors because they are able to transmit a number of diseases.
Also, the diseases they transmit are caused by infectious agents that include viruses, parasites, bacteria, etc.
Also, these vectors transmit diseases through their bite, although, there are some diseases that we can contact through their feces.
