Answer
Diseases can be transmitted by vectors through the bite or feeding activity of the vector on a host.
Solution
a
Vector Contact: Vectors such as ticks, mosquitoes, and sandflies come into contact with hosts and transmit diseases through their bite
b
Pathogen Transfer: During the feeding process, the vector injects the pathogen, which may be a virus or a parasite, into the host's bloodstream
c
Host Infection: The pathogen then infects the host, leading to the development of the disease
Key Concept
Vector-borne disease transmission
Explanation
Vector-borne diseases are transmitted to hosts through the bite of infected vectors, which are organisms that carry pathogens from one host to another.
