It was difficult to figure where this article had been referenced or discussed. It was included in a volume of History and Technology, so it would have been distributed along with the rest of the articles in the book. On "researchgate.net" it did not list anyone who had cited it, so my assumption is that it is not heavily referred to outside of this class.
On "researchgate.net" there are 28 separate citations of this article. They consist of a range of articles mostly dealing with the subject of biosecurity. I could not find any references that weren't on researchgate.
This article was published on PLOS.org and has been viewed over 96,000 times and has been cited over 175 times. An attempt to access the exact articles in which it had been cited was made, but that information was hidden behind a paywall.
Outside of this class and STS 6834 at Virgina Tech, it was difficult to find other places where this article was referenced. Because the article was published as part of a collection of articles related to this same topic, I assume that those who purchase the book for educational and research purposes read and discus the article at some length.
I was unable to find other pieces where this article was referenced and discussed.
