They reckon the mortality rate of Corona virus is currently 3.5%. There's also talk of 80% of the population getting it. So if it stays at 3.5%, the UK could face 1.8 million deaths/complications from Corona virus. The average death toll of flu each year is 17,000 so that is less than 1% of the amount of deaths/complications they are predicting from Corona virus.
However, when only 39 people have confirmed Corona virus right now and none have died, it does take a lot of imagination to assume 52 million people will catch it. Their numbers are very silly. There's one case in Scotland right now so it's a real stretch to say that 80% of the population will get it.
We're coming out of the cold and flu season too so I suspect it will be easier for people to tell they have it and reduce the spread.
Still, even if 10% of the population get Corona virus, that will be 6.6 million people and with a mortality rate of 3.5%, that could still be 231,000 deaths/complications for Corona virus which would be hard for the NHS to deal with.
Asking for people that have worked 40-50 years for the NHS to go back to work is ridiculous though. Also that most of these people will be late 50's and early 60's so a bit more at risk than others.
Obviously self care will be the most important thing. They need to work out who's most at risk and who isn't so people can be advised properly to limit the hospitals being overwhelmed.
I know nothing about the virus or anything but I very much doubt that even 10% of the population will catch it and if they were to, it would be over a long period of time, not just a couple of months. In almost 1 month since it coming to the UK, it's only gotten to 39 people. That's quite a slow rate of infection. If people follow all the guidelines, it shouldn't spread like wild fire and infect a large percentage of the population all at once
