What health issue could result from vector-borne diseases?

Vector-borne diseases are transmitted through vectors such as mosquitoes, ticks, and fleas, which can carry pathogens that lead to complex infectious diseases. These diseases can manifest in various ways, often affecting multiple organ systems and resulting in a wide range of symptoms that can complicate diagnosis and treatment. Some examples of complex infectious diseases include malaria, Lyme disease, Zika virus, and dengue fever, which can lead to significant health complications and long-term health impacts.

While other health issues might be associated with vector-borne diseases, such as skin conditions or mental health issues arising from the stress of dealing with illness, the core impact of these diseases is their ability to introduce varied and complicated infections to the human body, making the option related to complex infectious diseases the most relevant and accurate choice in this context.
