Verified step by step guidance1
Step 1: Understand the question is asking about the bloodborne viral disease that affects the greatest number of people in the United States, so focus on prevalence data for each disease listed.
Step 2: Review the epidemiology of each disease: Hepatitis B, Ebola, HIV/AIDS, and Hepatitis C, noting their modes of transmission and typical number of cases in the U.S.
Step 3: Recognize that Ebola is rare in the U.S. with very few cases, so it can be excluded from being the most prevalent.
Step 4: Compare the prevalence of Hepatitis B, HIV/AIDS, and Hepatitis C in the U.S. population, noting that Hepatitis C has a higher number of chronic infections than the others.
Step 5: Conclude that Hepatitis C affects the greatest number of people in the U.S. among the options given, based on its higher prevalence and chronic infection rates.
