Vector competence refers to the intrinsic ability of a vector, such as a mosquito or tick, to acquire, maintain, and transmit a pathogen to a susceptible host. This competence is influenced by various factors including the vector's genetics, environmental conditions, and interactions with the pathogen and host species.

A susceptible host is an individual who is at increased risk of developing an infection due to factors like weakened immune function, age, or underlying health conditions. Understanding the characteristics that make a host susceptible is crucial for developing effective infection control and prevention strategies.

Environmental conditions refer to the various factors and influences that affect the living organisms and ecosystems within a particular area, including climate, soil, water, and biological elements. Understanding these conditions is crucial for assessing ecological health, planning sustainable development, and mitigating environmental impacts of human activities.
