You're listening to shortwave from NPR.

Maddie, Sifaya here.

So maybe by now, you've completed at least one leg of your holiday travel.

Me, I was just at the airport a couple of weeks ago, but I kind of wish I had known about

today's episode before that.

Maybe you were more comfortable at the airport if you didn't know that you didn't.

That's a good point, you're right, baby.

So let me introduce you.

Hello, Tannina.

I'm Nina Ikonen.

Nina and her colleague, this is Karita Savo-Lanenko.

Karita, our microbiologist in Helsinki, in Finnish Institute for Health and Welfour.

And a couple of years back, they got to thinking about how we don't have a ton of scientific

studies looking at how infectious disease spreads in what Nina and Karita call major hubs,

ports, train stations, airports, where we spent a lot of time during the holidays.

So they worked out a study to look at germs in their hometown airport in Helsinki.

And you should remember that even though we have just looked at the airports in Christmas

time, we have to remember that almost.

Ah, when we called the Christmas shopping, and there is very much frequently touch places

and people with coughing on.

Yes, it's also high time for us, then this is also high time for viruses.

Yes.
