Prevention Measures

To prevent the spread of COVID-19 (coronavirus), please follow these steps—as well as the rest of the information outlined on this page:

  • wash your hands frequently with soap and water or an alcohol-based hand sanitizer;
  • get a COVID-19 vaccine(s) and booster when eligible;
  • wear a mask, depending on your setting and circumstances;
  • avoid close contact with other people who are ill;
  • cough into your elbow; and
  • stay home if sick.

Visit the CDC website for other resources and suggestions.


All visitors and members of the university community may now choose whether to wear masks on campus, unless they are in clinical settings, including the campus dental clinic, or have received university approval for an exception.

Please note that some individuals will still wear masks full time for a range of possible reasons. We ask that you respect their decisions.

Hand Hygiene

Studies show that effective handwashing can reduce the spread of respiratory illnesses by as much as 20%. Below is specific guidance from health officials.

The Centers for Disease Control (CDC) provides extensive guidance on handwashing; among its key recommendations are to wash hands for no fewer than 20 seconds (about the time it takes to sing “Happy Birthday” twice), and if using hand sanitizer, make sure it has at least 60% alcohol.

The World Health Organization has even more detailed hand hygiene guidance. Please pay particular attention to pages 3 and 4 of this document.
