| This! I'd even go further, that's not the entire story. Finding particles on a surface doesn't mean you are in present danger. If you're standing on the savannah and you spot a troop of resting lions half a mile down with binoculars, it doesn't mean they are going to jump you the next second. What I'm saying is that if days old, dried particles are found in a scrub from a ceiling board, that's still a vast difference from finding those same particles on a door knob. Where you find particles and the type of surface (cardboard vs. stainless steel) matter as well. Which is why the simplest, most ubiqutious advice is still the most effective: Don't touch your face. Wash your hands with soap for 20 seconds. Wipe down surfaces you actually touch regularly like door knobs, counter tops, keyboards and so on. Sneeze / cough in your elbow instead of your hand. Use disposable tissues. Apply rigorous physical distancing to avoid aerosols from others. Air your living spaces daily. If you're sick yourself, self-isolate. Wipe down groceries or packages if that makes you feel more at ease. Per how the World Health Organization is informing:

And if you can't see something dangerous but are told over and over again "it's everywhere", well, that's bound to cause an existential scare. It helps to know that we understand that basic sanitary measures are already very effective in their own right. We also have to understand that the statement "particles of virus have been detected after 17 days in a cabin" also applies to any virus or micro organism. You could be staying in a hotel room with old spittle particles stuck behind a cupboard and never be the wiser. |
