Among the listed pathogens,Hepatitis Chas thehighest risk of seroconversion following a percutaneous exposure, though it's important to note thatHepatitis Bactually has the highest overall risk. However, since Hepatitis B is not listed among the options, the correct choice from the available ones isHepatitis C.
“The average risk of seroconversion after a percutaneous injury involving blood infected with hepatitis C virus is approximately 1.8 percent”.
The other options are not bloodborne pathogens typically associated with high seroconversion risks after needlestick or percutaneous exposure:
A. Shigella– transmitted fecal-orally, not percutaneously.
B. Syphilis– transmitted sexually or via mucous membranes.
C. Hepatitis A– primarily fecal-oral transmission, low occupational seroconversion risk.
