So this is my issue and why I asked if each contact should reset the clock to zero.
If you do the quarantine for yourself, technically yes, you should reset. If you do the quarantine for others, then, theoretically, they should quarantine too, as they came into contact with you.
It's near OCD levels of control, but it's how forward this horrible virus could work. Studies show that the standard incubation time is more like 5-7 days, after which the probabilities drop significantly; but they do not reach 0 until after AT LEAST 14 days (cases of infection have been reported at 12-13-14 days, if I am not mistaken).
I get home to my boyfriend and his brother talking in the living room later a friend dropped off a trash bag full of limes and lemons and chit chat in the kitchen. SHUT THE FRONT DOOR. Their not taking it seriously. Not keeping 6 foot away. My boyfriend was like then stay in the bedroom WE SLEEP TOGETHER! if you get it from them you give it to me. Leave it outside and move along. Oh but that rude. We have a video door bell talk though that! You have FaceTime. It's not just that I don't want the coronavirus as they think the 14 days runs even if you rolled around in spit on day 13.
Yep. Technically, quarantine means that you should start over counting. But real quarantine also means something is really not working in your situation.
If you are trying to protect yourself from infection, each person within 6 feet from you (or from any person who comes into close contact with you) is a - POSSIBLE - risk, each place which is not safe is at risk, each object, including the clothes and phone you go out or come home with are POTENTIAL risks. And parts of your body, like your hands or other exposed aeas, are POTENTIAL risks too, if you then put them in contact with your face.
HOWEVER: the less you (or any person who comes into close contact with you) interact with people, the lower the risk. The less people you meet or have around you, the lower the risk. The higher the distance, the lower the risk. The less physical contact, the lower the risk. The less you stay indoors in places with other people, the better. The less you touch around, the better. The less you touch your face, the better. The more frequently you wash your hands, the better. The more you clean the places and objects you frequent/stay in/use, the better.
So, for the average person, it's not a question of what takes away the risk, but of what reduces it enough. Keep in mind the risk is incremental, so for most people it should be enough to avoid touching their face (in general or at least with not freshly-washed hands), to wash or sanitize their hands (and phone!) frequently, to avoid sharing personal objects with others and to keep a 6 feet distance from anyone who does not do those things.
Each breaching of the rules means a higher risk, not a certainty, but you won't be sure of the effect until 1-2 weeks later. To keep anxiety in check, it must be said that most of the times a standard person taking the right precautions is not going to come dangerously in contact with the virus, unless they are in a zone where the virus is really spreading; this, however, is not technically quarantine, it's more like how to reasonably protect yourself but still go on with what part of your life it's still not forbidden, which is what people should do here in Italy, for example.
Things change A LOT if you are specifically dealing with infected people, in which case the protocol is way stricter and each breach is extremely dangerous.
If you decide to really quarantine, so if you decide to fully isolate yourself for 14 days, it may be to either avoid getting infected or to avoid infecting other people; If it is the first one, then your boyfriend is canceling it out in each one of those instances. If it is the second one, so if YOU are infected or are quarantined because you were in contact with an infected person, then your boyfriend, his brother and your friend are at risk and now they should quarantine too.
