I do feel the media is whipping up a frenzy, because that is what sells. I find it very frustrating because I feel it creates undue worry, when ordinary precautions of frequent handwashing are our first line of defense.
Personally I think the 'panic' is justified. Better to worry early than regret late. Especially in the UK, with one of the highest population densities in Europe. I might be more relaxed if I was in Canada, where you're more likely to be eaten by a stray Polar bear than bump into a stray virus. Well, for now anyway.
Unlike normal seasonal flu there is
no population immunity whatsoever to covid-19. Ignore the death rates for a moment -- concerning though they ought to be for those of us caring for vulnerable folk with dementia -- just consider the fact that everything in modern society is "just in time". Nobody holds significant stock to allow for supply problems, because that's inefficient. And there can't be many workplaces these days that qualify as "overstaffed". Quite the opposite!
So if a significant chunk of the workforce rapidly goes down with something that requires them to be off work, things can go to hell in a handcart rather quickly. Systemic failure is entirely possible in our highly interconnected world. So the slower this thing is allowed to spread, the more time we have to adapt and react to changing circumstances. So a bit of mild alarm is, IMO, justified when dealing with a new health threat.
Fortunately for me, I've always had a distrust of our comfortable, easy Western lives (and they are no matter how hard and complicated life may also be), so the larder's always well stocked, including things like long life milk. And the advantage of being a 24/7 carer is that nobody apart from Tesco and a few local dog walkers would notice if I self-isolated for about... oh, the rest of my life. ;-)
Anyway, while I agree that panic serves nobody well, with a million or so folk in the air at any one one, crisscrossing the globe in hours, it's vital that the scientific and medical community has as much time as possible to minimise the impact of new threats to health. Especially when reported statistics are likely to be the tip of an iceberg.
There wasn't a trace of hand sanitiser in any of the shops I visited today (rumour has it supplies to retail may be being diverted to healthcare etc), which is a shame because it's one of the gaps in my stockpile... if things get out of hand in the loo I can get through a lot of it to try and quickly sanitise Mum and the surroundings. But I've plenty of Dettol and I imagine a splash of mouthwash probably serves the same kind of purpose at a push.
Failing that, there's always the medicinal vodka at the back of the Christmas cupboard.
But you're right that hand-washing is more effective when done correctly in most circumstances. This is also a great time to practice not touching our faces. It's a hard habit to break.
So's typing essays. My New Year's resolution was not to waffle pointlessly, but at least I made it almost two months!
