Hello,
We don't have any information to give you at the moment but we are of course watching the situation very carefully in all of the countries we visit. Rest assured that we will inform you immediately if anything is going to affect your holiday.
If you have any specific medical concerns, I would strongly advise you to get in touch with your GP, as he/she will know much more about swine flu and how it might affect you.
Regarding your other question, China is 7 hours ahead of the UK.
Kind regards,
Olly, your editor
