Hello @askmihai
For some reason your comment was passed on.
Thank you for commenting and asking.
The lockdown, well, solving it.
Studying new things, taking advantage of the time available to learn other things. Going out only as much as necessary.
And you? How about this situation in your country?

Here we have some interesting measures for stores: mandatory masks.
For some stores we also have thermal screening, through which they measure the skin surface temperature of our hand. Claiming that flu like symptoms can be caused by a virus so dangerous that
is a scientific claim that requires scientific proof.
i have a curiosity:
What's the proof for the virus?
Yeah @askmihai, it's the same thing around here. To enter supermarkets there is a temperature check, hand washing with gel, mandatory use of mask, two meters distance between each person, new rule, new reality.
There are two types of tests for the virus, one is called indirect, which quantifies in blood the antibodies that the body creates against that specific virus, and the other is called PCR, which takes a sample through the nasopharynx, and this sample is the one that is tested (PCR), and this detects some specific fragments of the virus.
The reality is that the most accurate is to apply both tests at the same time, because together they achieve a success in 98% of cases.
PCR is not a diagnostic technique. What do you think about that?
hi @askmihai
PCR is a technique that I know, in the university I could know how it was done when I studied biochemistry. It has good specificity. But this is improved with the indirect study of IMMUNOGLOBULINS. Molecules that are produced when the body is exposed to certain pathogenic organisms, and that is how immunity works.
So both tests are used to make a more accurate diagnosis. Of course, this must always go hand in hand with the correct assessment of the patient, see their symptoms (signs and symptoms).
Believe me, I know what I'm talking about.
What do you mean by specificity?
