Frederick Cohan, the Huffington Foundation Professor in the College of the Environment, professor of biology, is a microbial ecologist whose course “Global Change and Infectious Disease” examines how human disturbance of the environment contributes to infectious disease outbreaks. He also researches the origins of diversity among both bacteria and viruses.
In early February, as the novel coronavirus was beginning to spread, Cohan wrote an article in The Conversation, co-authored with PhD candidate Kathleen Sagarin and Kelly Mei ’20, titled, “A Clue to Stopping Coronavirus: Knowing How Viruses Adapt From Animals to Humans.”
Cohan also was interviewed recently by The Wesleyan Argus about the biology of the coronavirus.
You teach a course on Global Change and Infectious Disease, which looks at how human disturbance of the environment can contribute to infectious disease outbreaks like the one we’re now living through. Can you give us a brief introduction to the course?
I teach this course every year or two, and there are usually over 170 students enrolled. I’m also in the middle of writing a book based on the course content. We talk about five categories of environmental disturbance that humans are creating or have created in the past that bring new diseases to us or exacerbate existing ones. The categories are: demand for food (hunting and agriculture), demand for land (living at high density), demand for travel, demand for energy, and demand for health care (including antibiotics).
