Impact of potential doctors' strikes on hospitals

The NHS is warning of a worst-case scenario over Christmas as an "unprecedented wave of super flu" drives infections across the country.  

An average of 2,660 patients were in hospital a day with flu last week - the highest ever for this time of year and up 55% on the week before.  

There is no peak in sight - so what's caused the predominant H3N2 strain to emerge and can the NHS cope with the extra pressure?
