Yeah, now let me get this straight: this virus is so powerful and deadly that you have to take a test when you don't even feel sick at all, so that you can find out whether you have it, and then if you do test positive you might or might not become very ill, but in any event you will need to be subjected to a fourteen day quarantine. Even then you can never be considered to be in sound health, you are merely asymptomatic. Never mind antibodies, you can't rely on natural immunity which may wane over a short period of time or may not be effective against new variants. You need to keep on testing continuously (every 72 hours) to find out if you are safe, in order to protect others. Always mask up (even when you are alone or outdoors), wash your hands, use sanitizers compulsively, and stay six feet away from all other individuals: --these measures are refferred to as "layers of protection," You need to apply as many "layers of protection" as possible at all times, lest you become infected between tests. Additional "layers of protection" are afforded by multiple injections. The more "layers of protection" the better. The injections don't actually keep you from becoming infected, but we "know" that you will experience much milder symptoms proportional to the number of shots you have received. Expect to abide by these as well as other future rules for the rest of your life, as the virus is constantly mutating into new, more transmissible variants and the danger will be perpetually increasing.
