Step 1: Understand the term 'incidence' which refers to the number of new cases of a disease occurring in a specific population during a certain time period.
Step 2: Review the epidemiology of each disease listed, focusing on their prevalence and incidence rates in the United States.
Step 3: Recognize that diseases like Ebola and Plague are rare or have very limited outbreaks in the U.S., so their incidence is very low.
Step 4: Consider that Malaria is not endemic in the U.S. and cases are mostly imported, so its incidence is also low.
Step 5: Compare Brucellosis and Rocky Mountain spotted fever, both of which occur in the U.S., and identify which has a higher number of reported new cases annually.
