Final answer:
The risk of HCV infection after occupational exposure is significant as 75%-85% of infected individuals become chronic carriers. Precautions like using PPE and following exposure protocols are essential since there is no vaccine for HCV. Regular screening and new effective medications are also important components of managing HCV risk in healthcare settings.
Step-by-step explanation:
The risk of infection following an occupational exposure to Hepatitis C Virus (HCV) can vary, but health-care workers should be aware that the transmission of HCV primarily occurs through contact with infected blood. Although the mean incubation period of HCV is about 45 days, and while some cases are asymptomatic or resolve spontaneously, approximately 75%-85% of infected individuals become chronic carriers. Unlike Hepatitis B Virus (HBV), HCV does not have a vaccine. Therefore, taking appropriate precautions is essential to minimize the risk of HCV infection. This includes the use of personal protective equipment (PPE) like gloves and face protection, proper handling and disposal of needles and sharps, and following strict protocols when managing exposure to potential infectious materials.
Moreover, since the symptoms of HCV are often mild or non-existent, routine screening for HCV is critical, especially for health-care workers with potential exposure. Despite the lack of a vaccine, new medications have significantly improved the treatment for HCV, and these are tailored to the specific genotype of the virus in the infected individual.
