What are the two main types of vectors that can transmit diseases to humans in Ohio?

Mosquitoes and ticks are recognized as the two main types of vectors responsible for transmitting diseases to humans in Ohio due to their significant roles in public health. Mosquitoes are well-known for spreading illnesses such as West Nile virus and Eastern equine encephalitis, while ticks are notorious for transmitting Lyme disease and Rocky Mountain spotted fever, among other tick-borne illnesses.

Both types of vectors have adapted to the local environment and are prevalent in the state, often infesting areas where humans live, work, and engage in outdoor activities. Their ability to carry and transmit pathogens makes them critical targets for public health monitoring and prevention efforts. The other choices, while they may involve insect vectors, are not primarily associated with significant disease transmission in humans within Ohio. Flies and fleas typically have a lesser public health impact in this region, whereas bees, wasps, ants, and spiders are more involved in other ecological roles, such as pollination or pest control, rather than being major disease carriers.
