Which of the following best describes what is happening with infectious diseases in the United States?
a. There is a continuing decrease in vector-borne infections.
b. There is a continuing increase in food-borne and waterborne infections.
c. Many airborne diseases are being spread by bioterrorists.
d. The rate of infection varies extensively by income and ethnic groups.
ANS: D
Probably one of the most profound failures in infectious disease control in the United States and elsewhere is that the successes are not equally distributed in the general population. Infectious diseases continue to be differentially distributed by income and ethnic groups, and the poor and minorities continue to experience the greater burden. There continues to be an increase in vector-borne infections, but there has been a decrease in food-borne and waterborne infections. There is concern that deadly pathogens will be weaponized by terrorists.
