Students’ Essays on Infectious Disease Prevention, COVID-19 Published Nationwide

by Olivia Drake • December 17, 2020

More than 25 students in Fred Cohan’s Global Change and Infectious Disease course have had op-eds published in media outlets nationwide. Cohan, professor of biology and Huffington Foundation Professor in the College of the Environment (pictured), assigns the op-ed writing as part of his course and offers students extra credit if they are able to get their work published.

As part of the BIO 173: Global Change and Infectious Disease course, Professor Fred Cohan assigns students to write an essay persuading others to prevent future and mitigate present infectious diseases. If students submit their essay to a news outlet—and it’s published—Cohan awards them with extra credit.

As a result of this assignment, more than 25 students have had their work published in newspapers across the United States. Many of these essays cite and applaud the University’s Keep Wes Safe campaign and its COVID-19 testing protocols.

Cohan, professor of biology and Huffington Foundation Professor in the College of the Environment (COE), began teaching the Global Change and Infectious Disease course in 2009, when the COE was established. “I wanted very much to contribute a course to what I saw as a real game-changer in Wesleyan’s interest in the environment. The course is about all the ways that human demands on the environment have brought us infectious diseases, over past millennia and in the present, and why our environmental disturbances will continue to bring us infections into the future.”

Over the years, Cohan learned that he can sustainably teach about 170 students every year without running out of interested students. This fall, he had 207. Although he didn’t change the overall structure of his course to accommodate COVID-19 topics, he did add material on the current pandemic to various sections of the course.

“I wouldn’t say that the population of the class increased tremendously as a result of COVID-19, but I think the enthusiasm of the students for the material has increased substantially,” he said.

To accommodate online learning, Cohan shaved off 15 minutes from his normal 80-minute lectures to allow for discussion sections, led by Cohan and teaching assistants. “While the lectures mostly dealt with biology, the discussions focused on how changes in behavior and policy can solve the infectious disease problems brought by human disturbance of the environment,” he said.

Based on student responses to an introspective exam question, Cohan learned that many students enjoyed a new hope that we could each contribute to fighting infectious disease. “They discovered that the solution to infectious disease is not entirely a waiting game for the right technologies to come along,” he said. “Many enjoyed learning about fighting infectious disease from a moral and social perspective. And especially, the students enjoyed learning about the ‘socialism of the microbe,’ how preventing and curing others’ infections will prevent others’ infections from becoming our own. The students enjoyed seeing how this idea can drive both domestic and international health policies.”

A sampling of the published student essays are below:

Alexander Giummo ’22 and Mike Dunderdale’s ’23 op-ed titled “A National Testing Proposal: Let’s Fight Back Against COVID-19” was published in the Journal Inquirer in Manchester, Conn.

They wrote: “With an expansive and increased testing plan for U.S. citizens, those who are COVID-positive could limit the number of contacts they have, and this would also help to enable more effective contact tracing. Testing could also allow for the return of some ‘normal’ events, such as small social gatherings, sports, and in-person class and work schedules.

“We propose a national testing strategy in line with the one that has kept Wesleyan students safe this year. The plan would require a strong push by the federal government to fund the initiative, but it is vital to successful containment of the virus.

“Twice a week, all people living in the U.S. should report to a local testing site staffed with professionals where the anterior nasal swab Polymerase Chain Reaction (PCR) test, used by Wesleyan and supported by the Broad Institute, would be implemented.”

Kalyani Mohan ’22 and Kalli Jackson ’22 penned an essay titled “Where Public Health Meets Politics: COVID-19 in the United States,” which was published in Wesleyan’s Arcadia Political Review.

They wrote: “While the U.S. would certainly benefit from a strengthened pandemic response team and structural changes to public health systems, that alone isn’t enough, as American society is immensely stratified, socially and culturally. The politicization of the COVID-19 pandemic shows that individualism, libertarianism and capitalism are deeply ingrained in American culture, to the extent that Americans often blind to the fact community welfare can be equivalent to personal welfare. Pandemics are multifaceted, and preventing them requires not just a cultural shift but an emotional one amongst the American people, one guided by empathy—towards other people, different communities and the planet. Politics should be a tool, not a weapon against its people.”

Sydnee Goyer ’21 and Marcel Thompson’s ’22 essay “This Flu Season Will Be Decisive in the Fight Against COVID-19” also was published in Arcadia Political Review.

“With winter approaching all around the Northern Hemisphere, people are preparing for what has already been named a “twindemic,” meaning the joint threat of the coronavirus and the seasonal flu,” they wrote. “While it is known that seasonal vaccinations reduce the risk of getting the flu by up to 60% and also reduce the severity of the illness after the contamination, additional research has been conducted in order to know whether or not flu shots could reduce the risk of people getting COVID-19. In addition to the flu shot, it is essential that people remain vigilant in maintaining proper social distancing, washing your hands thoroughly, and continuing to wear masks in public spaces.”

On Sept. 22, faculty, staff, and students gathered on Zoom for a “Talk It Out” that related to the Theater Department’s upcoming production of SLABBER. Directed and created by Katie Pearl, assistant professor of theater, SLABBER is an open-air, interactive, socially distanced performance that brings viewers directly into the research and experiments of a group of people who are trying to identify a mysterious condition, known only as “slabber.” The interdisciplinary conversation, titled “Dis/Ease: Contagion and Pandemics in Our World and Its Stories” was facilitated by Luna Mac-Williams ’22, pictured at top, center.

The SLABBER performance invites viewers to consider notions of social and physical contamination and asks whether it’s possible to come close to someone else across a great distance. During the “Talk It Out,” guest speakers Fred Cohan, Huffington Foundation Professor in the College of the Environment, professor of biology; and Anthony Hatch, associate professor of science in society, offered their insight on how pandemics and contagion play out in our world and in our stories. Participants discussed the topics of contagion and how concepts of “dirty/clean” are changing social constructs.

Cohan spoke about the idea of purification. “When biologists learned about the microbiome, we lost the idea that there was something pure about our bodies, and the more we can scrub ourselves of those nasty bacteria, the better our lives would be. And it turns out, now it’s the opposite,” he said. “How hard do you really want to scrub to make yourself pure? It would be a dangerous exercise, and nobody really knows how bad an idea that would be.”

Hatch, who worked as an HIV/AIDS educator in the 1990s and early 2000s, noted that scholars find repetitive themes with the emergence of new infectious epidemic and pandemic diseases. “It’s quite easy to vilify a particular group that you believe is responsible for what has happened. Now, we have the so-called ‘China virus,’ which is a racist ploy designed to take attention away from the lack of leadership and [terms of] providing testing, which should happen. We saw this in 1918. . . . This has happened with everything from AIDS to Zika, and now with the COVID-19 pandemic. . . . We’re asking, who’s bringing the infection, what’s the source of the infection, how do we prevent the infection?”

“There’s a word I want to drop into the conversation and that is stigma,” Pearl said. “I’m thinking back to that moment, in the beginning [of the pandemic], when you wouldn’t want to put a mask on because you wouldn’t want people to think you were sick. The stigma around dirtiness is so huge, it keeps us from putting on that external marker of protection, to protect you from other people, and that is what has taken us down. It’s the stigma.”

The discussion was sponsored by the Creative Campus Initiative, Office of Academic Affairs, and the Theater Department. Theater Department “Talk It Outs” occur at least once a semester, and serve as a way to invite the larger Wesleyan community into an interdisciplinary, open conversation around the issues the productions are framing. SLABBER will be performed Oct. 16–18 on the Center for the Arts green, and will be open to 48 audience members each night.

Frederick Cohan

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).

Wesleyan faculty frequently publish articles based on their scholarship in The Conversation US, a nonprofit news organization with the tagline “Academic rigor, journalistic flair.” In this article, Fred Cohan, professor of biology, Huffington Foundation Professor in the College of the Environment, PhD student Kathleen Sagarin, and Kelly Mei ’20 explain how viruses like coronavirus—and several others over history—spread from animals to humans, what determines the size of the outbreak, and how behavioral modifications and technology can stop the spread.

A clue to stopping coronavirus: Knowing how viruses adapt from animals to humans

As the novel coronavirus death toll mounts, it is natural to worry. How far will this virus travel through humanity, and could another such virus arise seemingly from nowhere?

As microbial ecologists who study the origins of new microbial species, we would like to give some perspective.

As a result of continuing deforestation, “bushmeat” hunting of wild animals and caring for our domestic animals, the novel coronavirus will certainly not be the last deadly virus from wild animals to infect humans. Indeed, wild species of bats and primates abound in viruses closely related to SARS and HIV, respectively. When humans interact with wild animal species, pathogens that are resident in those animals can spill over to humans, sometimes with deadly effects.

CNN: “What the ‘Woke Student’ and the ‘Welfare Queen’ Have in Common”

“Every age seems to need a bogeyman, some negative image against which good people measure themselves,” writes President Michael Roth ’78 in this op-ed. Roth compares today’s bogeyman, the “woke” college student, with those of past eras—the “welfare queen” and “dirty hippie”—and seeks to build understanding and dispel negative misperceptions of activist college students. “The images of the welfare queen and of the woke student are convenient because they provide excuses to not engage with difference, placing certain types of people beyond the pale,” he writes. “These scapegoats are meant to inspire solidarity in a group by providing an object for its hostility (or derision), and educators and civic leaders should not play along.”

2. Los Angeles Times: “Opinion: Our Food Is Tainted with E. Coli, Yet the FDA Is Rolling Back Safety Rules”

As yet another food-borne E. coli outbreak sickens Americans, Fred Cohan, the Huffington Foundation Professor in the College of the Environment and professor of biology, and Isaac Klimasmith ’20, argue in this op-ed that more can and should be done to prevent dangerous contaminations of our food supply. The Food and Drug Administration (FDA) has rolled back rules that “would have required monitoring and treating irrigation water for E. coli,” a major cause of these outbreaks. “We should not be surprised that a regulation-averse administration would disregard the science of food safety, but it is concerning that consumers have become complacent about yearly outbreaks of E. coli contamination and largely silent about the rollback of food safety regulations,” they write.

3. The Washington Post: “What Happens When College Students Discuss Lab Work in Spanish, Philosophy in Chinese or Opera in Italian?”

Stephen Angle, director of the Fries Center for Global Studies, professor of philosophy, and the Mansfield Professor of East Asian Studies, is interviewed about Wesleyan’s efforts to promote language study, including the new Cultures and Languages Across the Curriculum (CLAC) initiative, through which students can study a range of disciplines in other languages. For example, Angle teaches a Mandarin-language section of Classical Chinese Philosophy, a course historically taught in English. Read more about CLAC and Wesleyan’s language instruction here.

Nicole DelGaudio ’18 samples the rhizosphere of a juniper tree.

This spring, a research team from Wesleyan traveled to Death Valley National Park to explore the ways bacteria diversifies in extreme environments.

Death Valley, located about 130 miles west of Las Vegas, is a below-sea-level basin known for being the hottest place on earth and driest place in North America. The average rainfall is less than 2 inches, annually.

“National parks are ideal for research, in general, because the land is protected indefinitely from commercial development,” said team leader Fred Cohan, professor of biology, professor of environmental studies. “Death Valley is a nice model system for exobiology because of its extreme habitat.”

Cohan, along with graduate student Jerry Lee, Bella Wiener ’19 and Nicole DelGaudio ’18, traveled to California May 29 through June 4. During this time, the researchers trekked through miles of parched — and often prickly — landscapes seeking to sample root soil, or rhizosphere, from various plant species, each over a wide range of elevations that differ notably in their temperatures.

Professor Laura Grabel, pictured sixth from left, attended the March for Science in New Haven, Conn.

Numerous Wesleyan faculty and students in the sciences attended the March for Science in different parts of the state and country on Earth Day, April 22.

Laura Grabel, the Lauren B. Dachs Professor of Science and Society, professor of biology, professor of environmental studies, professor of feminist, gender and sexuality studies, spoke at the New Haven march.

“I decided to march because science is being seriously threatened by the Trump administration,” she explained. “Trump has not filled almost all of the science positions, has no science advisor, and is using little evidence-based thinking in his decision making. Some of his appointments are puzzling and scary. From my perspective as a stem cell scientist, appointing Tom Price, who has consistently opposed embryonic stem cell research, as head of Health and Human Services presents a real danger to the future of this work just as therapies are entering clinical trials.”

Fred Cohan

Frederick Cohan, professor of biology, professor of environmental studies, has recently been elected to the Connecticut Academy of Science and Engineering (CASE). Set to be inducted during the 42nd Annual Meeting and Dinner on May 22, 2017, Cohan will join 23 others as “Connecticut’s leading experts in science, technology, and engineering,” and the academy’s newest members during their ceremony at the University of Connecticut.

In line with CASE’s mission to honor those “on the basis of scientific and engineering distinction, achieved through significant contributions in theory or application,” Cohan’s work has led to the “development of a comprehensive new theory for the origin, maintenance, and evolutionary dynamics of bacterial species diversity that integrates ecological and genetic criteria; and to the initiation and co-development of associated software tools, which allow microbiologists to identify distinct bacterial species from DNA sequence data.”

Cohan is a graduate of Stanford University, where he earned a bachelor’s degree in biological sciences in 1975. He went on to earn his PhD in organismic and evolutionary biology from Harvard University in 1982. His professional work takes him across the biological and environmental world, including, but not limited to topics such as microbial ecology, evolutionary theory, origins of bacterial diversity, molecular systematics and gene cluster analysis, horizontal genetic transfer and bacterial transformation.

Cohan Presents Research at Microbial Ecology Symposium

by Olivia Drake • September 13, 2016

Frederick Cohan, professor of biology, professor of environmental studies, presented his research poster, “Genetic Sweeps by Whisk Brooms and Garage Brooms — the Role of Ecology” at the 16th annual International Symposium on Microbial Ecology, held Aug. 21-26 in Montreal. Cohan presented his models on the origins of bacterial species, in particular that the rate a bacterial group forms new species is determined by the foods it consumes.

Microbial ecology is the study of microbes in the environment and their interactions with each other.

The International Society for Microbial Ecology is the principle non-profit scientific society for the burgeoning field of microbial ecology and its related disciplines. ISME fosters the exchange of scientific information by organizing international symposia as well as specific workshops, sponsoring publications, and promoting education/research. The society offers financial and travel awards during its symposia and provides services to the scientific as well as the wider community.
