A needlestick injury (NSI), also known as a percutaneous injury, occurs when a needle accidentally punctures the skin. Most commonly happen to occupational hazards involving a health care worker.
Approximately 35.7 million health care workers worldwide are exposed to NSI risk, according to the World Health Organization (WHO) data. Hence, the most worrying consequence of NSI is the transmission of blood-borne pathogens that cause serious or even fatal infections.
