What are vector-borne diseases? Explain the role of vector in disease transmission with an example.

Answer 1

• Vectors also known as carriers are generally some insects and animals that carries disease causing microbe.
• The diseases which are caused by vectors are called vector-borne diseases. For example: Malaria
• When a female Anopheles mosquito bites an infected person, pathogen enters into the vector's body along with the blood meal.
• Now, when the same mosquito bites a healthy person, the pathogen gets released into the bloodstream of healthy person and hence the person gets infected with malaria.
