Science Friday
A virus hunter in Nigeria has thoughts on the Ebola outbreak

Thank you.

Science Friday

The Bundibujo virus or strain of Ebola is different from the Zaire strain simply because it has diverged.

Science Friday
A virus hunter in Nigeria has thoughts on the Ebola outbreak

It has evolved.

Science Friday
A virus hunter in Nigeria has thoughts on the Ebola outbreak

It has followed a different evolutionary path.

Science Friday
A virus hunter in Nigeria has thoughts on the Ebola outbreak

And for that reason, the virus is quite divergent.

Science Friday

from those that you strain.

Science Friday

And that divergence actually creates its own challenge because diagnostics, vaccines, and drugs are often very strain-specific because they are targeting some very specific epitopes in any virus.

Science Friday

And because the bunjibujo

Science Friday

virus has not been studied extensively.

Science Friday

That is a reason why now we want to use this outbreak in order to not only sequence the virus, but actually leverage the data that will be coming from the outbreak to develop the necessary countermeasures.

Science Friday

And these countermeasures are drugs, vaccines, and diagnostics.

Science Friday
A virus hunter in Nigeria has thoughts on the Ebola outbreak

Not really.

Science Friday
A virus hunter in Nigeria has thoughts on the Ebola outbreak

I think, you know, when we had our last outbreak, when the Bujumbuja outbreak, I mean, occurred, I think that was probably 2007.

Science Friday
A virus hunter in Nigeria has thoughts on the Ebola outbreak

There were, I mean, at that time, genomic sequencing was not really at the state where it is now.

Science Friday
A virus hunter in Nigeria has thoughts on the Ebola outbreak

It was a technology that was in infancy.

Science Friday
A virus hunter in Nigeria has thoughts on the Ebola outbreak

And at that time, we didn't have the capability to actually to generate the data through genome sequencing.

Science Friday

And between 2007 and now, a lot has changed.

Science Friday
A virus hunter in Nigeria has thoughts on the Ebola outbreak

And they will really want to take advantage of it now to study this virus in a way that wasn't done before in order to develop the countermeasures as I mentioned before.

Science Friday
A virus hunter in Nigeria has thoughts on the Ebola outbreak

Simply because there is, you know, the global health community in general and then the governments in Africa in particular have not really invested in

Science Friday

If we had intentionally invested in doing, you know, to do viral disease surveillance or to do pathogen genomic surveillance, we could have probably come across, you know, the viral sequence state.
