A British backpacker has revealed how she was struck down with a deadly disease which she had initally mistaken for a bad hangover.

lysha Pyrgotis, from Bradford, West Yorkshire, was left vomiting and suffering 'extreme diarrhoea' after catching typhoid fever on the remote Indonesian party island of Gili Trawangan in June this year.

She had initially thought her symptoms of the bacterial infection, which can kill one in five of those infected if they don't seek treatment, was a result of having one too many drinks the night before.

But when she became physically unable to get out of bed due to feelings of being 'delirious' combined with deep muscle and bone pain, the 27-year-old knew she was in a lot more bother than first assumed.

She said: 'I couldn't concentrate at all, that's when I started to panic. The guy I was travelling with at the time started to realise I was quite poorly, I wasn't hungover.
