Which virus has the highest transmission rate from a needlestick injury?

Hepatitis B is known to have the highest transmission rate from a needlestick injury. This is primarily due to the virus's stability outside the human body and its infectious nature. Hepatitis B virus (HBV) can survive on surfaces and in body fluids for extended periods, making it more likely to transmit through exposures such as needlestick injuries. The risk associated with needlestick injury is much higher for Hepatitis B compared to other viruses such as Hepatitis A, Hepatitis C, and HIV.

While Hepatitis C and HIV can also be transmitted via needlestick injuries, their transmission rates are generally lower than that of Hepatitis B. Hepatitis A, on the other hand, is primarily transmitted through fecal-oral routes and is less relevant in the context of needlestick injuries. Understanding the difference in transmission rates can help healthcare workers in prioritizing their safety and implementing proper precautions in clinical settings.
