The second case did not go into quarantine until a positive test result was received.
The third case is believed by the OPH to be travel related and the patient has been under self-quarantine since returning from abroad.
Demographic information is not being released by the OPH at this time due to privacy concerns for patients testing positive for COVID-19.
That includes where in the county the cases are and, in relation to the second confirmed case, where the patient went before going into quarantine.
There have been 47 tests in the county as of 3 p.m., March 21, but testing has only recently become more available through private labs, which require a physician’s order.
