Which statement is NOT correct?
Explanation & Rationale
A. "Sharing needles is a big risk factor for hepatitis.": Percutaneous exposure to contaminated blood is a primary transmission route for Hepatitis B and C viruses. Sharing injection equipment allows for the direct inoculation of viral particles into the bloodstream of a susceptible host. This remains a significant public health challenge in preventing bloodborne pathogen spread. B. "Chronic hepatitis increases the risk for liver cancer.": Persistent inflammation from Hepatitis B or C leads to progressive hepatic fibrosis and eventually cirrhosis. This chronic cellular damage and regeneration cycle predisposes hepatocytes to malignant transformation into hepatocellular carcinoma. Longitudinal monitoring of these patients for oncological changes is a standard clinical requirement. C. "Newborns should receive the Hepatitis B vaccine.": Universal neonatal immunization is the standard of care to prevent vertical transmission and early childhood acquisition of the virus. The first dose is typically administered within 24 hours of birth to ensure long-term immunological protection. This strategy has drastically reduced the global prevalence of chronic HBV infection. D. "Health care workers should get a Hepatitis C vaccine.": Currently, there is no commercially available vaccine for the prevention of the Hepatitis C virus. While vaccines exist for Hepatitis A and B, Hepatitis C prevention relies entirely on standard precautions and post-exposure protocols. This statement is scientifically inaccurate because the vaccine technology does not yet exist.
