WHO Release New Guidelines For COVID-19
–Sharing is Caring–

After a few reports came out regarding the airborne transmission of the novel coronavirus, the World Health Organization has released new guidelines on Tuesday on the transmission of Covid-19 but refused to confirm that the virus spread through the air.

Few Covid-19 outbreaks have been reported in crowded indoor places, which suggest the possibility of aerosol transmission like in restaurants, fitness classes, or during choir practice, WHO acknowledged in its latest transmission guidance.

However, further research is urgently required to study such instances and investigate their significance for COVID-19 transmission, said WHO.

Previously, a group of aerobiologists who specialize in the spread of disease in the air had issued an open letter that urged WHO to update its guidance on COVID-19 to include aerosol transmission.

Based on the evidence available so far, WHO said the COVID-19 coronavirus spread through close contact with the infected people or with surfaces contaminated with the infected individual’s saliva, droplets, or respiratory secretions released while sneezing, speaking, singing, or coughing.

The new guidelines released by WHO warn people to avoid crowds and, in addition to social distancing, maintain good ventilation in buildings and wear masks when physical distancing is not possible.

Jose Jimenez, a chemist at the University of Colorado who signed the letter published on Monday in the journal Clinical Infectious Diseases, said it is becoming clear that the pandemic is driven by super-spreading events, and that the best explanation for many of those events is the aerosol transmission.

But there isn’t enough evidence yet on the airborne transmission of SARS-CoV-2, said Dr. Anthony Fauci, director of the U.S. National Institute of Allergy and Infectious Diseases in a press briefing on Thursday. But he also added that its reasonable to assume the possibility. And that’s why they are asking people, especially those without symptoms to wear masks, to see if it can mitigate the spread of COVID-19.

According to the previous COVID-19 guidelines released by WHO, specific medical procedures were considered the only chances of airborne transmission of the SARS-CoV-2 before.

An aerosol expert at Virginia Tech, Linsey Marr, who contributed to the letter, encouraged the World Health Organization for acknowledging the possibility of airborne transmission.

But Linsey Marr also said that WHO is using an outdated definition of droplets and aerosols, and they are too focused on the size and distance droplets travel.

Not many diseases spread through tiny floating particles or aerosols. They include two highly contagious pathogens tuberculosis and measles that can remain in the air for hours and hence require extreme precautions to prevent exposure.

According to WHO, aerosols are particles that can float in the air for long, with a size under 5 microns. But much larger particles can also contribute to infection, said Jimenez and Marr.

They said the droplets and aerosols should be distinguished based on how infection occurs, not on size. If a person is infected by contact, they are droplets, and if infected by inhaling viruses, they are aerosols.

Breathing aerosols is a concern when the individuals are in close contact or in the same room, said Marr.

Forging ahead with care and compassion

Amidst the uncertainty and stressors of the dual scourges of Covid-19 and structural racism, a number of MIT professors are forging thoughtful ways to support students’ well-being and scholarly development. Several Committed to Caring honorees shared their approaches for being proactive and including their research groups in decision-making, including Associate Professor Gene-Wei Li, Professor Paola Cappellaro, Professor Cathy Drennan, Professor Colette Heald, Professor Warren Seering, Associate Professor Anna Mikusheva, and Associate Professor Kerri Cahoy.

Transparency and collaborative approaches — at every level — are deeply beneficial in empowering students and building resilience in the face of considerable challenges.

Providing a roadmap

Weeks before shutdown orders in Massachusetts, Professor Gene-Wei Li emailed his lab, outlining the likely course of the coming weeks, both in terms of infectious disease progression and public health efforts. On March 1, Li encouraged students to begin gathering the supplies they needed to work from home.

Attending to the financial precarity of some graduate students, Li offered to help students who could not afford to stockpile a month’s worth of groceries and household supplies. Vitally, Li notes, “acting early is important to ensure research continuity and reduce emotional impact when an avalanche of restrictions are implemented.”

Professor Paola Cappellaro reached out to students in her classes and laboratory to offer support and advice as local Covid-19 cases emerged in March. She helped students weigh their options and access financial support as they made hurried decisions about their living situations. Cappellaro’s laboratory had transitioned to Zoom group meetings prior to MIT’s ramping down of research, which enabled them to be intentional with their discussions of research continuity.

Participatory decision-making guided by principles

Collaborative decision-making is helping Li’s lab weather the crisis. The group was among the first laboratories to begin to return to campus in June. In talking with his advisees, Li provided two principles to guide their decision-making: “safety cannot be sacrificed,” and “your careers must advance.”

He then sought their input on what a research ramp-up should look like for their lab. Providing clear structures for student involvement in decision-making was very helpful in ameliorating the high level of uncertainty and lack of control the disruptions engendered.

Li also paid attention to the little things, inviting his students to help build a “system (and not Poisson statistics) to ensure that there [was] at most one person per room at any given time.” Based on these conversations, he installed convex mirrors in shared spaces so students would know if someone else was already in a room they were about to enter. Li also installed iPads: the first few students who returned to lab are now recording and streaming their experiments, providing a resource to students who are at an earlier point in their graduate careers.

Creating deliberate interactions

Unplanned meetings are lost with remote work. Li observes, “the very nature of scheduled meetings makes them more formalized and less personal.” He has sought to address this by offering regular open Zoom hours. Being responsive and adapting communication patterns to students’ needs has been very effective in building a cohesive remote lab group.

With the loss of spontaneity, Professor Cathy Drennan is finding that problems often escalate before students raise them with her. In the past, a simple hallway interaction or tagging along on a dog walk offered informal mechanisms for students to express challenges to her before they had worsened.

Drennan is reflecting on past instances where she was annoyed with herself for working on a time-sensitive project in her office, where she could be easily interrupted. Now, she realizes that the informal lab interactions were a critical piece of her role as a principal investigator, ensuring stability and well-being within the lab group. Presently, she works to build in more availability to lower the threshold for students to raise obstacles.

Reaching out

For many, advising has turned in a more personal direction. Professor Warren Seering writes that “our students are facing unusual difficulties … We need to be on call for our students, and conversations need to include wellness check-ins to give students the chance to ask for help or guidance.”

Professor Colette Heald has made more time available for meeting with students and has introduced Zoom tea and coffee breaks, for unstructured conversation. She is very intentional about fostering the human side of mentorship. Heald finds it effective to spend “much more time sharing stories about how we are all adapting to this new normal and discussing issues in the news.”

Concurring, Professor Anna Mikusheva empathizes with the challenges students face. She writes, “in isolation, it’s very hard to stay focused and to maintain a connection with your community, peers, and advisors.” Mikusheva urges advisors to be “proactive” in checking in on students and maintaining regular meetings.

Building connections within a research group can be pivotal in persevering amid the torrent of upsetting news. “I try to nudge people to reach out to each other even in lockdown,” Cappellaro notes, “and indeed there’s been new collaborations among the group sprouting from this situation.”

Courageous conversations

Li is catalyzing conversations in his laboratory to process the traumatic histories of structural racism and sexism in this country and renew efforts to combat them. The Li lab has introduced “critical, structured social engagement” as part of their regular interactions, focusing on topics such as “racial bias in science and higher education” and “deepened gender bias in the pandemic.”

As Li notes, such conversations have always been a part of their lab’s culture, though they have become “more structured in light of our increasingly unstructured society.” Providing a trusted and safe forum in which to discuss these topics can help students as individuals as well as help advance the reforms that are vitally needed in academia.

Modeling self care

Adaptations to advising have required concerted thinking regarding needs and limitations. Vitally, faculty members are facing unusual burdens from the public health crisis as well.

Like many faculty parents, professors Kerri Cahoy and Gene-Wei Li’s hours have stretched considerably with the need to care for their young kids as well as support their advisees. They try to make transparency and self-care a regular practice, demonstrating humility with advisees.

“I don’t try to hide that I’m a real person with conflicting priorities,” Cahoy says.

Li shared with his lab that he was feeling burnt out, and took a short break in April. Their openness normalizes struggles, which is conducive to students sharing their own difficulties, and enables conversations about accommodations.

Grappling with the uncertainty of the pandemic and the ongoing harms of structural racism is a considerable burden for many graduate students. Having the support of professors who are Committed to Caring provides students with the resources and tools to rise to the challenge.

Learning by doing, remotely

Avatar

Published

on

Experiential learning is alive and well at MIT — even when it’s remote.

Just ask Julian Zulueta, a sophomore in biological engineering. Last May, he spotted an intriguing social impact internship opportunity in the PKG Public Service Center newsletter: The CDC Foundation, a Congressionally-chartered nonprofit created to support the Centers for Disease Control and Prevention (CDC), was seeking remote students to assist with the Covid-19 response.

He applied — one of 60 candidates for two spots — and got the position. As a member of the CDC Foundation’s Workforce Strike Team, Zulueta interfaced with state and local health departments, with a particular focus on the Midwest region. Drawing on his introductory Python experience at MIT, he analyzed requisition data and created visualizations to detect trends in resources and in the effectiveness of medical interventions. He also studied correlations in universities’ response to Covid-19 and helped establish new professional growth policies within the CDC Foundation.

The internship was eye-opening, and it stoked his interest in exploring public health careers further. “To my surprise, I realized that public health was more than just the opinions of doctors and nurses. Rather, it extends to incorporate ideas related to public policy design and statistics, which can favor majority groups and lead to disparities in health outcomes,” Zulueta says.

Zulueta’s experience is heartening to Kate Trimble, senior associate dean and director of the Office of Experiential Learning (OEL). “When the pandemic first hit, we were very concerned that students were going to miss out on the hands-on experiences that are so critical to their personal and professional development,” she says.

The PKG Center newsletter that changed Zulueta’s trajectory was the result of concerted efforts by OEL and other campus partners to help students whose summer plans had fallen through or were up in the air — efforts that seem to have paid off. While data from industry partners are not available, statistics from the PKG Center and the Undergraduate Research Opportunities Program (UROP) show a marked uptick in participation this summer. A total of 213 students worked remotely in intensive social impact programs through the PKG Center (compared to 136 in 2019), and 1,523 students participated in UROP (compared to 975 last year).

And, even better, those efforts served as a roadmap for rethinking similar experiences for the mostly-remote fall academic semester. “It was really inspiring to see the MIT community spring into action to adapt in-person UROPs and internships — and even global experiences through MISTI — to a remote format,” says Trimble. “In retrospect, we shouldn’t have been surprised; the ‘magic’ of MIT lies in hands-on learning, and everyone here excels at problem-solving.”

Retooling the best laid plans

Some students were able to extend or reconfigure in-person opportunities into remote versions. When sophomore Sherry Nyeo realized that she would not be able to intern for the summer at a biotech company in Israel, she applied to continue a UROP she started in February at the Whitehead Institute for Biomedical Research, working on RNA secondary structure. Nyeo, who is majoring in electrical engineering and computer science and biology, remotely analyzed the lab’s data and ran the data pipeline.

“I do appreciate that I got a firsthand experience of what goes behind research, and I had a lot of opportunities to present papers to my lab during journal club,” Nyeo says. Her computational data analysis, along with figures she generated, have been incorporated into a paper on the SARS CoV-2 genome, on which she is listed as a co-author.

Marisa Gaetz, a 2020 MIT graduate who is staying on to pursue a PhD in mathematics, managed to tweak her ESG-PKG Fellowship for The Educational Justice Institute (TEJI) at MIT, a nonprofit that leverages education and technology to address mass incarceration.

Before the pandemic, she was planning to help facilitate a summer program for Boston-area youth who have been drawn into the criminal justice system. Instead, she adapted the in-person elements of the program into engaging online activities that encourage discussions about wrongdoing, ethical dilemmas, and moral worth. In addition, Gaetz researched interactive boards with Zoom capabilities and secured funding to install the technology in correctional facilities in Suffolk County, Massachusetts, and Maine, ensuring that TEJI can continue to offer its signature classes in these facilities.

“Even though many experiences have to be remote right now, Covid has also exposed a lot of different needs, and so there’s a lot of new opportunities to do impactful work as well,” Gaetz says.

Sophomore Catherine Lu is one of many participants in MIT International Science and Technology Initiatives (MISTI) who were able to convert their global education experiences into remote versions. Originally, the civil and environmental major was slated to travel to Tulum, Mexico, to help restore a lighthouse into a coral education center. Instead, Lu designed and created a virtual reality experience of the lighthouse, which allows users to visualize and interact with the physical space and, by extension, promotes awareness of coral restoration efforts.

“Through this virtual reality world, we are able to expand even more on the idea of coral education, since much of the audience we’re targeting are people who might not live near coral or are not able to physically travel there,” Lu says.

Seizing a singular opportunity

For juniors Carlos Mercado-Lara and Evan Gwozdz, shifting gears to a remote summer opened up unique opportunities they could not have anticipated.

Once Mercado-Lara found out that his MISTI-France program was cancelled, he channeled his time and efforts into SciTeens, as a PKG Center IDEAS grantee. SciTeens, a nonprofit he co-founded in high school, connects underrepresented high school students from underserved communities with online mentors in STEM. This summer, Mercado-Lara and the SciTeens team collaborated with an organization in Zimbabwe to mentor local teens working on science projects.

“That was great, because it was our first time working internationally with students and establishing trust with another organization,” says Mercado-Lara, who is majoring in biological engineering. The experience also helped him shift his focus for the future. “If I had done an internship, it would have helped my career and allowed me to explore a career path, but over the summer I was able to realign some of the things that I want to continue doing for the next few years while I’m at MIT, and hopefully grad school.”

Gwozdz ditched his plans to find an internship in March, since many of them were being cancelled. He reached out to faculty doing interesting research in his major, chemical engineering, and landed a remote UROP in the Zack Smith lab, which investigates polymer membranes for gas separations.

Since he couldn’t physically be in the lab, he focused on learning about molecular simulations, using software to model experimental polymer systems. “Simulations are heavily used in the field, but they haven’t been explored thoroughly in the Smith lab,” Gwozdz explains. By delving into simulations, he created a niche for himself and has become a valuable member of the team. “With this remote project, I think I was able to contribute as much to them as I received myself,” he says.

Expanding ELOs to all undergraduates

The experiences that Zulueta, Nyeo, Gaetz, Lu, Mercado-Lara, and Gwozdz had are indicative of the diversity and range of opportunities available to students, Trimble says.

“The all-remote summer allowed some students to think outside the box and explore amazing experiences — like social impact internships or work in their own communities — that they might not have considered before. And many students used their positions to make a difference on urgent issues like the pandemic, climate change, and racial justice.”

At the same time, Trimble notes, OEL and other offices learned a great deal over the spring and summer about how to support virtual experiential learning. “We’re putting all of that into practice this academic year,” she says.

To that end, MIT is guaranteeing all undergraduates a paid experiential learning opportunity (ELO) this year. Students who are on campus or at home can earn up to $1,900 while working in a wide variety of remote or on-campus ELOs. The OEL’s new website serves as a guidepost, with resources organized into six tracks: research; public service and social impact; innovation and entrepreneurship; global opportunities; teaching and learning; and opportunities for first-year students.
