If attending an OTI Education Center Region 1 class here in New England, please adhere to the following advice:

NOTE about seasonal illness and exposing yourself and others. If you are not feeling well or have symptoms of the common cold, shortness of breath or respiratory ailments, coughing, sneezing, or feel feverish, please call the Center to postpone to another course if at all feasible. Stay home if you are sick.

While in class: Try to avoid people who are sick. Cover a cough or sneeze with a tissue. Cough into your upper sleeve or elbow. Do not cough into your hands. Consider alternatives to hand-shaking, and if you do, use hand-sanitizer.

Wash your hands often with soap and water for at least 20 seconds, especially after going to the bathroom, before eating, and after blowing your nose, coughing, or sneezing. If soap and water are not readily available, use an alcohol-based hand sanitizer with at least 60% alcohol. Always wash hands with soap and water if hands are visibly dirty. Avoid touching your mouth, nose, or eyes.
