What are vector-borne diseases?

• A. Diseases caused by genetic mutations
• B. Diseases that are airborne and highly contagious
• C. Diseases transmitted by vectors, such as mosquitoes or ticks
• D. Diseases related to poor nutrition

Answer: (C)

Vector-borne diseases are those illnesses that are transmitted from one host to another through vectors, which are typically organisms such as mosquitoes, ticks, or fleas. These vectors serve as agents that carry and spread the pathogens, such as viruses, bacteria, or parasites, that cause the diseases to humans or other intermediate hosts. For instance, malaria is transmitted by Anopheles mosquitoes, while Lyme disease is spread by ticks. This definition highlights the role of vectors in the transmission process, distinguishing vector-borne diseases from other types of diseases that may arise from different causes, such as genetic mutations, poor nutrition, or airborne spread. Understanding the vector's role is crucial in controlling the spread of such diseases, as managing vector populations or preventing their bites can significantly reduce the incidence of vector-borne diseases.
