“Healthcare workers (HCWs) are at a significantly increased occupational risk for a range of infections. These include infections that cause substantial illness and occasional deaths in HCWs (Decker and Schaffner, 1996, Eriksen et al., 2005 and Klevens et al., 2007), or are associated with healthcare associated infections (the majority of which are caused by bacteria). Various infectious agents can be transmitted from patients to HCWs and vice versa (Weber et al., 2010). As droplet transmission is a major mode of transmission of some pathogens, I-BET151 mw standard infection control measures like hand washing alone Trichostatin A may not be enough to prevent HCW transmission or outbreaks. HCWs can transmit infections such as tuberculosis, varicella, and influenza by the airborne route (Weber et al., 2010); it is less well appreciated that airborne and other routes of transmission of certain bacterial pathogens may occur. There is a low awareness

of bacterial infections as an occupational health risk for HCWs. In addition, antibiotic resistant bacteria are a very significant problem facing hospitals, and HCWs play a role in their transmission. Bacterial respiratory tract infections are generally not considered a major occupational problem for HCWs. A growing body of evidence suggests that the risk of bacterial respiratory

infections is increased by co-infection with viruses and vice-versa, and this has been studied mostly around the relationship between influenza and pneumococcus (Klugman et al., 2009, Madhi and Klugman, 2004, MMWR, 2009 and Zhou et al., 2012). Bacterial load in the nasopharynx is also thought to be related to risk of invasive disease or bacterial–viral co-infection (Klugman et al., 2009). A meta-analysis showed frequent bacterial co-infections during influenza outbreaks (Wang et al., 2011). Streptococcus pneumoniae, Haemophilus influenzae, Staphylococcus spp. and other Streptococcus spp. are the commoner causes Linifanib (ABT-869) of bacterial secondary infection following an influenza-like illness (ILI) ( Wang et al., 2011). Case studies documenting the role of HCWs in transmission of S. pneumoniae are absent, possibly because this is usually not an outbreak-associated disease, and because the pathogenesis of invasive disease is complex (including the relationship with prior colonization). Further, HCWs with invasive pneumococcal disease may go unreported in the occupational context ( Sherertz et al., 2001). On the other hand, Bordetella pertussis outbreaks among HCWs have been widely reported ( Addiss et al., 1991, Gehanno et al., 1999 and Pascual et al., 2006), with such outbreaks attributed to airborne transmission through droplets ( Nouvellon et al., 1999).
