Majority of HCWs reported that their jobs involved exposure to BBFs. Setting of intravenous lines, surgical operations and recapping of needles were the most commonly reported activities being carried out during exposure to BBFs. This is similar to the findings of other studies which reported that recapping of needles (Leszczyszyn-Pynka et al., 2004), performing surgical procedures (Lal, Meghachandra, Singh, Malhotra, & Ingle, 2006), handling surgical equipment (Gańczak, Szych, & Karakiewicz, 2012), handling medical wastes (Rapparini et al., 2007), disposal into sharp containers (Do et al., 2003) and blood withdrawal (Muralidhar, Singh, Jain, Malhotra, & Bala, 2015) were the common procedures leading to exposure to BBFs. Nurses reported the highest use of needles and exposure to BBFs. This is similar to findings by Hsieh et al. (2006) and Hadadi et al. (2008) and is probably because needles are used mostly by nurses (WHO, 2014a). About half of HCWs reported accidental exposure to BBFs in the last year with staff in the surgical departments reporting the highest accidental exposures, the highest number of splash of BBFs on intact skin and open wounds, needle stick injuries and cuts from scalpel. Surgical staff were three times more likely to experience accidental exposure to BBFs than those in the Laboratory departments. Surgeons have contact with BBFs of patients during surgical operations and non-availability of relevant devices has been reported as the most important factor militating against the use of universal precautions by surgeons in developing countries (Olapade-Olaopa, Salami, & Afolabi, 2006). Splash of BBFs on intact skin was the most commonly reported exposure. Other reports by WHO (2014a), Braczkowska et al. (2010), Davanzo, Frasson, Morandin, and Trevisan (2008) and Lal et al. (2006) indicated that needle stick injuries were the commonest type of exposure to BBFs. This is probably because these studies were conducted among doctors and nurses alone while our study included other groups of health workers such as laboratory scientists, laboratory attendants and ward maids who do not frequently use needles. The high frequency of exposure by splash of BBFs on intact skin in this population constitutes a significant risk as it can be a source of infection for Ebola virus disease among health care workers (WHO, 2014b).
