Implications for practice and research

  • The use of a powered, air-purifying respirator with coverall may protect against the risk of contamination better than an N95 mask and gown but was more difficult to don.

  • The creation of future studies is necessary to compare the risk of contamination during removal of personal protective equipment, PPE).
