Couple of important items here:
1. Read the guidelines put out by the WHO, and if you want a second opinion read the Canadian ministry of Health suggestions. Generally the CDC is correct, but there has been a large amount of politically motivated modifications to their suggestions.
2. This thing has only existed since last December, consequently the knowledge and suggestions on how to deal with it have evolved and changed, with a lot of people seeing mixed messages. That has made things pretty confusing. Always ask "when was this information last updated? If it is more than a month old go look for something more up to date.
3. There are a bunch of different tests for CV19, and some of them have larger error margins than the other. No idea which test you took, but it could be unreliable. They need to shut down certain test methods now that better ones exist but some people are still making money off the older methods.
4. Wash your hands, wear a mask, social distancing, all that.
5. Don't be too surprised if we end up shutting down the country again to get this under control. (See where we are in January.) If we could do a really good lockdown for about 6 weeks we could beat this. Instead it is going to drag on for months.
Abbott Labs has a really great testing setup for this now, you get results in under 15 minutes. If we could get this thing in every hospital, pharmacy, CVS, Walgreens, etc, we could get the sort of test-track-isolate-control strategy we need.

There is a lot of junk information out there too! Some information that is simple to digest and from sources that I trust:

Oh, in case you are wondering why I have so many opinions n this, as some of you know I am an electrical engineer, and for the last 15-18 years I have been concentrating on medical device design.
Stay safe everyone!
