Some diseases exclusively transmit through the airborne route in natural setting (e.g. tuberculosis), while other diseases mainly transmit through the droplet or contact modes but short range respiratory aerosols are generated during high risk procedures which increases the risk of infection transmission (Roy and Milton, 2004) . For example, the primary mode of influenza transmission is thought to be droplet (reflected in guidelines which largely recommend surgical masks), but there is increasing evidence that it is also spread by shortrange respiratory aerosols (Bischoff et al., 2013; Tellier, 2009) . Current evidence suggests that human to human transmission occurs predominantly though direct contact with blood and body secretions, (World Health Organization (WHO), 2014a) and this is the basis of the WHO and the CDC recommendations for facemasks to protect HCWs from EVD. ./cache/cord-269770-7hau5yge.txt ./txt/cord-269770-7hau5yge.txt
