Its not the practical side of things we have to worry about, we can quite easily clean a house and have no contact with anyone, they can easily pay on line. But if people think we' re going to be unaffected they've got a nasty shock coming to them. If we follow other countries examples then isolation , banning of public events etc will follow and ultimately alot of people in other work sectors wont be able to work and that will impact us. If the moneys not coming in, people will cut back and window cleaning is a luxury people can do without. Add public paranoia to the mix and we will be getting cancellations.
As for just putting it down to sensationalism , some people need to wake up. Never in my lifetime have worldwide governments acted in this way, and its becoming clearer why. The mortality rate of flu varies but is about 0.15 %, So far coronavirus its 3.5% and that figure will only rise as its based on figures of people who still have it and so may add to the amount of fatalities. Add in the mix that there are serious doubts as to the accuracy of death figures given by china and Iran then that figure is only going to get higher. We're on the verge of something quite extraordinary. It looks like everyones life is going to be affected one way or another.
