+## COVID-19 precautions
+
+We strongly recommend all participants to wear a medical grade mask (N95, KN95, etc.) during OHW. Everyone has different health considerations and risk tolerance, and we would like to lower the risk of COVID-19 infections for everyone. 
+
+If you have close contacts with people who have tested positive or been in crowded confined space for a prolonged period, please consider taking a test before joining OHW in person.
+
+We plan to have remote connection via Zoom during the entire Northwest satellite event. If you test positive less than 5 days before OHW starts (i.e., on or after August 10), please stay home/in the hotel and let the organizers know. We will help ensure smooth connections for tutorials and facilitation of other activities.
