North Central Public Health District officials say a Hood River resident who was at the Northern Wasco County Aquatic Center in The Dalles last Thursdaytested positive for COVID-19 the next day.  Local health officials are stressing that as long as pool patrons abide by guidance, they are not at increased risk for contracting COVID-19.  The pool allows groups of up to 10 people, but requires that they keep at least six feet away from other parties.  Any close contacts of the Hood River resident will be identified by the Hood River County Health Department and contacted by them.  Modified rules at the North Wasco Aquatic Center include allowing only smaller groups of swimmers to attend any of four 90-minute sessions per day.  The facility is thoroughly cleaned between sessions and the lobby and locker rooms are closed, as is the concession stand.
