Final answer:
An exact count of healthcare personnel infected by blood-borne pathogens is not provided, but healthcare workers face substantial risk, with catheter-related bloodstream infections estimated at 80,000 cases per year in the US. Protective protocols and vaccination help reduce risks.
Step-by-step explanation:
It is challenging to provide an exact number of healthcare personnel who have been infected with blood-borne pathogens due to varying reporting standards and practices globally. However, healthcare workers are at significant risk for infections, such as Hepatitis B (HBV), especially when in contact with blood, body fluids, or through injuries from instruments like needles. The World Health Organization (WHO) has estimated up to 80,000 catheter-related bloodstream infections annually in the US alone.
Measures to reduce the risk of infection include using protective gear, proper sanitation practices, and post-exposure treatment with hepatitis B immunoglobulin (HBIG) and vaccination. Despite vaccinations being available and recommended by the CDC, not all healthcare personnel are vaccinated or respond to the vaccine, thereby maintaining a level of risk. Additionally, accidental needle sticks remain a danger, particularly in settings involving drug users or where phlebotomy is frequently practiced.
