1. Water
2. Food
3. Germs
4. Blood
Correct Answer: 4
Rationale 1: Water is incorrect because hepatitis A is transmitted through food and water contaminated by feces.
Rationale 2: Food is incorrect because hepatitis A is transmitted through food and water contaminated by feces.
Rationale 3: Germs is incorrect because germs is a general term encompassing bacteria, viruses, fungi, and protozoa.
Rationale 4: Hepatitis B (HBV) is found in blood and certain body fluids. It is spread when blood or body fluid from an infected person enters the body of a person who is not immune. HBV is spread through having unprotected sex with an infected person, sharing needles or "works" when "shooting" drugs, needle sticks or sharps exposures on the job, or from an infected mother to her baby during birth. Exposure to infected blood in any situation can be a risk for transmission.
