Scientists are worried about ticks.

They say they’re starting to pose more of a health risk here in the UK, as our climate warms and urban areas spill into green spaces.

But what are ticks, what kind of disease can they cause – and how much of a problem are they? We go on a tick hunt in Richmond Park and then head back to the lab to meet the ticks we’ve collected. We find out why new species of ticks and new diseases could be coming our way - and what you can do to keep safe.

Also this week, we answer your questions on the impact of noise on our health following our recent programme.

And we delve into the fascinating world of measles. It’s the most contagious virus in the world – by a long way. What is it about this virus that makes it so spectacularly good at infecting us?
