What about this - in 2018, 4,655 people were diagnosed with TB in England.
No-one seems to be panicking about that.
The epicentre of TB on the planet is India, but no-one is talking about stopping flights in and out of the sub-continent.
Scares like this are catnip to the media, and they are making the most of it.
The fact is, the majority of people will ignore the government's advice about hand-washing and so on.
This virus will spread, peak, and die away again.
We should keep a sense of proportion.
