Lyme disease in the Northeastern United States is an example of which disease pattern?

Explanation:
Endemic disease pattern refers to a disease that is consistently present in a geographic area at relatively steady levels. Lyme disease in the Northeastern United States fits this pattern because the tick vector, reservoir hosts, and climate create a background level of transmission that leads to ongoing, year-after-year cases in the population. This is different from an epidemic, which would involve a sudden surge in cases above what is normally expected over a short period. Carrier status describes individuals who harbor the pathogen without showing illness, not the regular, geographic presence of disease.
