Raises concern for heightened transmission risk from carriers with URI; hypothesis-generating for targeted masking in clinical practice.
Does a concurrent viral upper respiratory infection increase airborne dispersal of S. aureus in a nasal carrier?
A concurrent viral upper respiratory infection can dramatically increase the airborne dispersal of S. aureus from a nasal carrier, which can be mitigated by wearing a surgical mask.
Sherertz et al. (1996) studied this question.
