infectious diseases, particularly in Hanta, but also in Ebola and others, you're most transmissible.

You actually have the peak load of virus just before you pass.

And so she would have been extremely infective, that poor patient.

So therefore, that could be one of the reasons.

It isn't.

As long as we know where they are and they're asked to do the right thing, which is isolate at home, declare their symptoms, you've really got to take an approach of reassuring these contacts, these people that we need to know, you need to tell us the moment you feel any symptoms and we'll look after you.

Certainly, St Helena has limited medical care out there on that island, so if anybody does

show positive signs, then they will need to be medevaced somewhere with higher level of care.

But once we know who's on the list, now finding that this person has gone positive is actually a sign that surveillance is working.

So in a way, I'm more reassured by that.

Correct.

Yes, absolutely.

And this is why you're seeing, you know, effectively pouring cold water on the Adalas to become an epidemic or a large outbreak because it doesn't usually transmit.

In these cases, it has.

But once we know, even with Ebola, once we know where the cluster was,

and we know the context or even the context of the context, that's sort of the second tier.

If we have control of that, then we can get on top of this.

It's in the initial phase, if we didn't know what this disease was, or if these people were scattering to the wind and we didn't know where each one was, then we'd have a bigger problem.

But if, you know, passenger manifests, especially on these kind of ships, are very, very robust.

Yeah, absolutely.
