With a national shortage of COVID-19 tests emerging, health officials are advising those without symptoms to talk with their doctor before seeking one.  Hood River County Health Department Health Officer Dr. Christopher Van Tilburg says the shortage locally is not drastic, but it is significant.  Van Tilburg said those with symptoms, in high-risk populations, or in close contact with someone who has had a positive COVID-19 test are prioritized to receive a test.  North Central Public Health District Health Officer Dr. Mimi McDonell said earlier this week getting test results back in a timely manner was as much a problem as the availability of the tests themselves.
