PORTER

So when you hear a virus described as H5N1 or H1N1 or whatever, that's because it's got a different H and a different N from many others?


MCNALLY

Yes exactly, it's the type of molecule on the surface - so H5 will react with a different antibody from H1 - and that's how they're classified and typed.

So assuming the swab gets to the lab and the virologist - the department - are on to it straightaway, how quickly can they confirm that somebody would have a particular strain of flu at the moment?


MCNALLY

Well in a standard case that would be a couple of days turnaround, obviously at the moment because we're in the situation we are and the WHO have announced that we're now in phase four any suspected samples will be sent directly to a reference lab where they will go straight into molecular tests and you know with the speed at which we do - the UK's very good at this obviously - because we've got WHO EU reference labs we are well practised at doing this very, very quickly and you could be looking at within 12 hours - a turnaround of some form of an initial result.
