IntroductionCurrently, needlestick injuries (NSIs) are one of the most important occupational hazards among healthcare workers (HCWs) globally. According to WHO, more than two million occupational exposures to sharp injuries occur among 35 million HCWs annually [1].NSIs increase the risk of over 20 types of infectious diseases among HCWs, including hepatitis B, hepatitis C, and HIV [2]. According to the Centers for Disease Control and Prevention (CDC) and European Agency for Safety and Health at Work (EU-OSHA) reports, there are more than 385,000 and 1,000,000 NSIs cases annually among hospital HCWs in the United States and Europe, respectively [3,4]. WHO statistics also show that NSIs cause 16,000, 66,000, and 1,000 cases of HCV, HBV, and HIV per year among HCWs, respectively [5]. The prevalence of various infectious diseases due to NSIs among HCWs is not a single and integrated phenomenon, rather is affected by several factors, such as vaccination rates among HCWs, access to appropriate worker protection
