Dr. Kevin Kelleher:

-----understand that a negative test is not an indication that one is free. It is one of the most important things we need to make sure people understand. Having these quick tests does not mean one no longer has to self-restrict. If one has the symptoms or has been a close contact, it does not obviate from the need to carry on restricting one's movements as a consequence. It is an important issue. It makes no difference whatsoever. We need people to understand that. The test is not a magic bullet which gives someone freedom at all. It is actually just an indication. One is still bound by the public health advice to restrict one's movement for whatever period it is, depending on the circumstances.
