Excellent experiment to show how our hands are germ central or interchanges!
Only started with the father, and dad had only touched 2 sons.
But at the end of the day, the whole family ended up glow in the dark on their hands, and faces, except for grandma!
And why was grandma fine?
Bcos she spent the whole day washing various things, and hence inadvertently washed her hands too!
So keeping our hand clean, wash or sanitise regularly.
And don’t forget, if we really really want to put on masks, then we should wash our hands before handling our masks, and wash our hands again after taking them off.
If not, our hands will be the viral interchange.
One video clip of people wearing masks, crying as they tell a story. So sad!
But uh oh! These folks went to wipe their tears away with their hands!
Natural, very human - instinctive too. But boy! That brings a viral load to our eyes, down the tear ducts into our nasal passages, down our throats and into our lungs!
That is how viruses like flu viruses and SARS and the Wuhan nCoV would typically spread among people. Via our hands, directly and indirectly!
Some ask why Macau os so kiasu - pax advised to wear masks on buses - and SG is less kiasu on advising our people to use masks only when we are not feeling well and are going out to see our doctor.
Well, it really depends on the levels of risks.
SG is at DORSCON Yellow, not yet Orange, and unlike to hit Red for the Wuhan virus.
We have little evidence of large scale community spread.
On the other hand, both HK and Macau have millions more China visitors, and hence proportionately more likelihood of infected patients among them.
This means community spread, and higher chances that a bus passenger standing next to us may be infectious even when he looks well.
And so Macau has a higher level of precautions vs Singapore.
