The trouble is that it isn't just the virus that will be the problem. It is the fear and disruption. I have posted before that I wouldn't book a holiday in the next few months because of the disruption at least as much as the virus- my flights mike get changed I might get stuck somewhere etc.
Now I have a new problem. I often fund my holidays from very modest savings invested in stocks and shares. Those modest savings have lost the price of a bl***y good holiday in the last week- so I will think much harder about withdrawing money and may wait until there is a recovery. Either way I am like many not booking flights.
