Final answer:
Vaccinations provide protection against Hepatitis A and B, reducing the incidence of these diseases. Hepatitis C, while not vaccine-preventable, can be treated with medication. Health-care workers follow strict protocols to prevent transmission in clinical settings.
Step-by-step explanation:
Vaccinations significantly reduce the risk of infectious diseases. The first vaccine many children receive is the Hepatitis B shot, offering protection against this severe liver disease. Prior infections may confer some degree of immunity, but vaccinations ensure a higher level of protection against future infections. Hepatitis A, B, and C are viruses causing liver infection, but they exhibit distinct modes of transmission and symptoms.
Hepatitis B was once prevalent among health-care workers, but mandated vaccinations decreased incidence rates. However, not all forms of hepatitis are vaccine preventable. Hepatitis C, for example, lacks a vaccine but can often be self-managed or treated with antiviral medications. In contrast, vaccinations are available for Hepatitis A and B, with Hep A vaccine providing additional protection against Hepatitis E.
For health-care workers, adherence to protocols like using protective gear and proper disinfection methods with solutions like 10% bleach is critical for preventing transmission of blood-borne pathogens, including Hepatitis B.
