Has anything you've looked at over the last few years surprised you? Anything that's maybe been counterintuitive? I'd love to hear some of those.

We've tested in so many different places, hospitals, Ministry of Defence bases, care homes, quarantining hotels, places where there's biosecurity issues such as abattoirs.

And sometimes we've found things that we're not looking for.

Sometimes we've found diseases that people don't even know are circulating in their community, like Giardia.

Sometimes we've been to environmental places where we found avian bird flu in lakes people are swimming in, so they're coming into contact with.

One of my favourites favorite project is sampling wastewater off aircraft so in the covid pandemic for example sampling the sewage that comes off planes people using the toilets on planes we'd assumed that even in the red list countries that those people who are on the planes were not meant to be carrying covid that every single plane we tested coming into Heathrow Airport or Bristol Airport and connector flights, they were all positive in the wastewater for SARS-CoV-2, which means that there were contaminated people on that plane, which means that, you know, they're entering the country and bringing it and seeding the population with new variant strains of COVID.

You know, when they were putting people in quarantining hotels, same thing, you know, they're meant to be negative, but we were just checking to make sure that they were in that period.

looking at the levels of norovirus in shellfish and also antimicrobial resistance.
