Oregon health officials have identified a third presumptive positive case of COVID-19 among state residents.  The third case is an adult Umatilla County resident who is hospitalized in Walla Walla.  State and local health officials are moving quickly to contact people who may have been in close contact with the individual who tested as a presumptive positive case.  The third case is not linked to travel to a part of the world with known cases of COVID-19.  It is considered a case of community transmission.  Preliminary reports indicate the person attended a youth basketball game at a gymnasium at Weston Middle School in Weston on Saturday.  Under federal Centers for Disease Control and Prevention and Prevention guidelines, other spectators who may have been in a closed environment with the individual would be considered “low-risk” exposures.  Athena-Weston School District officials have closed the gym and will conduct a deep cleaning out of an abundance of caution.  The gym is physically detached from the rest of the school, and health officials do not consider the separate school building to pose any risk of exposure.
