Keep in mind the mortality rate at the care home my sister works at is 25%. 10 died in one week from the usual winter bugs, flu, pneumonia.
The elderly have very little resistance to anything normal healthy people pass off after a few days.
I would like a breakdown of who actually is entering hospital and succumbing to the virus, like to bet mainly care home residents.
Infection rate is not exponential, it's detection that is increasing daily.
If you go looking, you find.
This is why Boris is not concerned, the virus has been in UK for months and people have not been dropping like flies.
