Healthcare workers suspected of being infected should be isolated and treated the same as any other patient until a negative diagnosis is confirmed. The severity of a specific problem is a principal determinant of the urgency and course of a field investigation and of any early intervention. Because of differences in knowledge, beliefs, and perceived impact of the outbreak, each group might draw different conclusions about causality from the same information.

Primary Prevention Thank you for taking the time to confirm your preferences. If there is a partial or total breach in PPE (e.g., gloves separate from sleeves leaving exposed skin, a tear develops in an outer glove, a needlestick) during patient care, the healthcare worker must move immediately to the doffing area to assess the exposure and implement the facility exposure plan, if indicated.
