Are you serious, a news crew actually went there to invade these peoples privacy, that is some sick $%^ right there.
They did...about a week or more ago.I am slightly surprised they haven't placed all seniors care homes on outbreak as a precaution (or at the very least, ban all visitors and be more proactive with potentially sick staff). The outlook is grim if it starts to tear through there.
Brilliant, you deduced that a black light will not allow you to see a bug that is so small you need an electron microscope to view itdoesn’t show up a virus...only shows up molecules that absorb in the UV area of the spectrum
This is pretty much the whole problem. Many people only have minor cold or allergy symptoms. They just shrug it off and spread the virus not realizing what they have. They get over it in a couple of weeks but spread the seeds of destruction everywhere.I think a lot more people are infected than what's reported.
Of course an old person suffering from intense flu symptoms will be tested and found positive. But what about younger people who have lesser symptoms, or are entirely asymptomatic. Those people are still infected and contagious, but are flying under the radar because they haven't been tested yet.
No, certain bond types (conjugated multiple bonds most often) absorb light at a certain part of the spectrum. What you see is the result of the absorption, the resultant light that is left over is what you see. So for example carotene (a molecule with multiple conjugated double bonds) absorbs in the blue/green area of the visible spectrum and you see orange as the colour "left over" from this absorption. Hence why carrots are orange. Back to why you see things with a black light....it's not dirt, it's just bodily fluids with the same characteristics described above in terms of molecular structure but this time they are absorbing in the UV area of the spectrum rather than the visible.Brilliant, you deduced that a black light will not allow you to see a bug that is so small you need an electron microscope to view it
... get a black light, darken your room and go check out your kitchen stove or your toilet.
And how do you know what light wavelength won't make this thing fluoresce?
... and it is reflections that you see not absorbed anything.
