The main problem with Corona is the possibility that the majority of the population will have it at the same time.
If people were infected at a steady rate over time, instead of all at once, the NHS, businesses etc would be able to cope much better.
The virus itself is not much worse than the flu. Like the flu the elderly and vulnerable are more likely to be badly affected and suffer complications such as pneumonia.
Whether Tom hanks or any other 'celebrity' gets it is irrelevant imo. Celebrity does not equal immunity.
