Klickitat County officials say its jump of 16 COVID-19 cases in nine days are linked back to the Memorial Day weekend and increased community activity.  A statement from the County’s Emergency Management and Health Department on Tuesday said a few of the cases are linked to known outbreaks in Oregon as well.  They add the cases have been a low risk to the county based on rapid case investigation and management done early in Oregon and with the help of the residents choosing to isolate.            Some of the other positive cases have been linked to previous close contacts which were able to be addressed very quickly through contacting all close contacts and asking them to self-quarantine.  The other remaining cases have been traced to travel to other counties and states.  Klickitat County officials note they entered phase 2 in Washington just one week ago and have yet to see the impact on case activity from that factor.  They expect to see increasing case activity simply due to the increased risk of more businesses and activities opening up.  They also stressed the importance of taking proper health and hygiene precautions to reduce COVID-19 activity.
