Objectives

Narrative objectives1

The specific aim of the present study is to determine if wearing a large respiratory droplet mask decreases the risk of acquiring an upper respiratory infection. The null hypothesis is that there is no difference in number of URIs acquired between groups, and that duration and severity of illness is the same. The rationale for doing this study is that if the hypothesis is true, then the use of masks may be reduced or eliminated for this type of purpose. This will save money and lessen environmental impact, as well as allow healthcare workers to interact with each other and with their patients with the full facial expression and other nonverbal communication at their disposal.
