We did a very similar experiment in our A-level Biology class to show how washing your hands makes a huge difference.Hallucigenia wrote:Not this again. No, there is pretty overwhelming evidence that masks are a massive net positive - this is an airborne disease, you need to worry about it getting into your lungs not a handful of virus particles getting onto your hands. Have a read of this thread :Lootman wrote:I have wondered myself whether masks might paradoxically increase infections. If the mask is providing any protection at all then the virus must accumulate on either the inside or the outside of the mask, or both. Then people keep touching them, removing them and putting them back on, placing them on the pub or restaurant table, putting their hands here and there, and so on.
So could face coverings actually be powerful vectors for the virus, which otherwise would just dissipate in the atmosphere, fall to the ground and die off?
Professional medical staff know how to handle masks, how often to change them, and so on. But I am fairly certain people wear the same face covering for days at a time, maybe weeks at a time, coughing into them, sneezing into them. It's kind of disgusting when you think about it, like using the same cloth handkerchief for days when you have a cold.

I'm not quite sure why the agar in the petri dishes is red, rather than the customary brown. Though maybe they added hemoglobin to more closely match a human organ.
Wear the bloody masks, keep your distance and wash your hands! None of this is exactly new to us.

PS I can't get Viz where I live, so reading some of the comments is really great fun. Keep 'em coming! Covid is caused by dirty toilet seats or a plot by the Illuminati?
