I've been traveling all over for work (including the US and UK) and what I've seen does NOT match this thread at all and I have not tested positive once (I've been tested every 3 weeks since June). Too much sensationalism in this thread.
I'm certainly not an over-reactor and I do believe the media can be a bit too much. However, in this case, i think it's very fair to say we should take some real pause and consider the situation thoroughly. I agree everything should be shutdown and borders closed off for a temporary period of time until we have a firmer understanding of the science.
Here is a good article to read
www.sciencemag.org
and a key paragraph from the article:
"One reason to be concerned, Rambaut says, is that among the 17 mutations are
eight in the gene that encodes the spike protein on the viral surface, two of which are particularly worrisome. One, called N501Y, has previously been shown to increase how tightly the protein binds to the angiotensin-converting enzyme 2 receptor, its entry point into human cells. The other, named 69-70del, leads to the loss of two amino acids in the spike protein and has been found in viruses that eluded the immune response in some immunocompromised patients.
A fortunate coincidence helped show that B.1.1.7 (also called VUI-202012/01, for the first “variant under investigation” in December 2020), appears to be spreading faster than other variants in the United Kingdom. One of the polymerase chain reaction (PCR) tests used widely in the country, called TaqPath, normally detects pieces of three genes. But viruses with 69-70del lead to a negative signal for the gene encoding the spike gene; instead only two genes show up. That means PCR tests, which the United Kingdom conducts by the hundreds of thousands daily and which are far quicker and cheaper than sequencing the entire virus, can help keep track of B.1.1.7."
Again, there are still many unknowns and everything will be fine at the end of the day. However, we are too far along and too close to getting this pandemic eliminated (under control?) to start letting our guard down. I personally don't want to take any steps back.
