Redding Health Officer Doug Hartline says at-home COVID-19 test results do not need to be reported to the local health department.  But he says individuals must follow through with informing close contacts of positive findings to prevent the spread.  He notes that a negative test result means that the test did not detect the virus and does not rule out infection.  Repeating the test within a few days, with at least 24-hours between tests, will increase confidence in the negative result.  A positive result should result in isolation for 5 days, or longer if symptoms persist.
