Peter Jahrling, one of the country's top scientists, has dedicated his life to studying some of the most dangerous viruses on the planet. Twenty-five years ago, he cut his teeth on Lassa hemorrhagic fever, hunting for Ebola's viral cousin in Liberia. In 1989, he helped discover Reston, a new Ebola strain, in his Virginia lab.
Jahrling now serves as a chief scientist at the National Institute of Allergy and Infectious Diseases, where he runs the emerging viral pathogens section. He has been watching this Ebola epidemic with a mixture of horror, concern and scientific curiosity. And there's one thing he's found particularly worrisome: the mutations of the virus that are circulating now look to be more contagious than the ones that have turned up in the past.
When his team has run tests on patients in Liberia, they seem to carry a much higher "viral load." In other words, Ebola victims today have more of the virus in their blood and that could make them more contagious.
We spoke last week about his work studying the disease, how this Ebola virus may be more dangerous than others, and what that means for the epidemic. What follows is a transcript of our conversation, lightly edited for clarity and length.

Julia Belluz: What concerns you most about the virus circulating now?
Peter Jahrling: I want to know if this virus is intrinsically different from the one we have seen before, if it is a more virulent strain. We are using tests now that weren't using in the past, but there seems to be a belief that the virus load is higher in these patients [today] than what we have seen before. If true, that's a very different bug.
