Since some international travellers have expressed concern about the Swine Flu 'epidemic', and it's potential impact on LFACC...
A map of the current situation can be found here. At time of writing, the UK has 27 confirmed cases, from a population of 70 million - including 13 in London (London population - 10 million). Assuming these figures are correct, and ignoring the fact that those sufferers have probably been quarantined, this puts your current chances of encountering a carrier of Swine Flu in London at around 1 in 800,000. To put the risks in perspective, this is a lot less than the chances of being run over during your stay in London.
An extensive FAQ regarding Swine Flu can be found here.
Information from the NHS on how to avoid Swine Flu etc. can be found here.
Anyway, I hope the Swine Flu situation doesn't discourage people from travelling - and that includes the guests as well!
