哈佛大学
Harvard College students have been asked not to return to campus after spring break and to move out of their Houses and first-year dorms by Sunday. Remote instruction is set to begin March 23. Currently, Harvard has no documented coronavirus, but today the University announced two community members are being tested. Harvard College is providing students on financial aid with up to $200 to ship items home. Students should email the Registrar’s Office, registrar@fas.harvard.edu, to receive prepaid shipping labels. With the move to online learning, Zoom training is available to faculty members. Faculty have been asked to sign up for a Zoom account and complete training no later than March 20. A number of training sessions are available online and in person, including a video tutorial, a workshop, office hours, and one-on-one help. Harvard University IT has been working with Zoom to ensure the system can handle the high demand. The University has also issued travel and meeting and event guidance to the community. It has banned all work-related travel until at least April 30 and is strongly discouraging nonessential personal travel. University events or meetings of 25 people or more are discouraged.

MIT’s Response to the Challenge of Covid-19
The Commonwealth of Massachusetts declared a state of emergency due to the doubling of Covid-19 cases in the Greater Boston area.
All classes for today, Friday, March 13, have been cancelled.
We strongly advise all undergraduate students to accelerate their move out plans. MIT will reimburse travel change expenses and new reservation costs up to $500 for undergraduates who move up their departure to before Sunday, March 15 at midnight.
All students who have requested an exception from moving off-campus and have not yet received a determination will be contacted today with a decision.
MIT Libraries will suspend all in-person library services effective 5 p.m. today.
The MIT Police would like to remind all community members who will be working remotely from home to please follow the following procedures when securing their Institute offices and workspaces.
Shut down all computers.
Secure all valuables in a closed and locked desk or filing cabinet.
Secure all office windows.
Take all personal valuables home.
Make sure all office doors are pulled tightly closed and locked.

University announces further steps in response to coronavirus disease (COVID-19)
The University of Chicago is moving to remote learning for undergraduate and graduate classes for the entire Spring Quarter of 2020, beginning on Monday, March 30, the first day of the Spring Quarter.
University residence halls will continue normal operations until the end of Winter Quarter. Students who can return home at that point should do so. The University will continue to provide housing, dining, health, and other resources to students for whom travel restrictions or other circumstances require them to remain on campus for Spring Quarter. Other students should plan on vacating their on-campus housing by 5 p.m. on Sunday, March 22. Students who requested and have been granted spring break housing will still be able to stay through spring break.
Students will continue to receive financial aid and stipends.
The University and the University of Chicago Medical Center remain open.
The University of Chicago Laboratory Schools will also be moving to remote learning on March 30.

New COVID-19 actions; letter from University President Marc Tessier-Lavigne
FINAL EXAMS: The provost is asking instructors to make winter quarter final exams optional for undergraduate students. If a student chooses not to take a final exam, their grade should be calculated on work they have done in the course to date. It will be important for instructors to provide students with clear information about the choice that should be made, the deadline by which they have to choose, and how the final grade will be calculated if they choose not to take the exam. This guidance applies only to undergraduate students.
UNDERGRADUATE DINING BEGINNING SATURDAY: Due to the new county restrictions, beginning Saturday we will need to move to significantly modified meal service for undergraduates who are on campus.
SPRING UNDERGRADUATE HOUSING: For spring break and spring quarter, we will only be able to provide on-campus undergraduate housing and dining for a very limited number of students – those who have no other option than to be here.
If you are NOT in one of the above prioritized categories, we unfortunately need you to make plans to leave the campus as soon as possible but at the latest by Wednesday, March 18, at 5 p.m. We encourage you to make your plans quickly, as the external environment is changing quickly and we do not know if or when additional restrictions may be imposed.
REMOTE WORK: While we do not mandate telecommuting, we do want to increase the number of employees who are working remotely to the greatest extent possible, while doing so in a way that still supports the necessary operations of the university.
This also applies to graduate students and postdoctoral scholars in the research environment. We expect to provide further guidance on steps to be taken in the research environment in coming days.

COVID-19 – Moving courses online and other significant updates
Moving classes online when they resume after spring recess. When spring recess ends and through April 5 at the earliest, classes will be held using Zoom, Canvas, or other online tools. I know classes take many forms across the university, so this shift to online teaching and learning raises many questions. Deans will be communicating with their faculty and students to provide further details in the days ahead.
Asking students to remain home or return home when possible. We are asking Yale College students to remain at home after spring recess. For undergraduates who are on campus now, please make every effort to return home as soon as possible, and no later than Sunday, March 15.
Graduate and professional students are encouraged to remain off-campus and participate in online instruction, unless being on campus is necessitated by the nature of their research or academic programs. More information is forthcoming from the deans of each school.
Limiting international and domestic travel
Maintaining continuity of research and teaching. While the health of Yale’s faculty, staff, and students is our top priority, the university also remains committed to its mission of research and education. Faculty members and graduate and professional students are asked to carry out their teaching responsibilities online. Research groups have been asked to make contingency plans to maintain research continuity, which may involve faculty, staff, and students continuing to work and study in labs, machine shops, offices, and other campus facilities. The university will maintain central services to support research and teaching.

What You Need to Know
NEW To further support students able to leave residence halls, Columbia will provide up to $500 to any undergraduate who needs help in this regard.
NEW As of Monday, March 16, only designated personnel required to perform essential functions should report to work on-site. All other employees are asked to report to work virtually according to procedures announced and coordinated by your departments and schools.
NEW Updated recommendations are available for affiliates who have had direct close contact with a person diagnosed with COVID-19 or who have returned from travel to a CDC Level 2 or CDC Level 3 country in the past 14 days.
Columbia will remain open, but all classes for the remainder of the semester will be conducted online. Students who are able to move out of undergraduate residence halls are encouraged to do so.
All Columbia business travel, both international and domestic, is now suspended for all affiliates.
No Columbia student, faculty, or staff has been diagnosed with COVID-19.
Columbia continues to closely monitor the evolving COVID-19 developments and will be making a decision in the coming weeks about Commencementceremonies. Details will be shared with all school planners and posted here as soon as possible.

University issues further COVID-19 guidance, accommodations and criteria for remaining on campus
*Leaving campus*. We realize that for those of you leaving campus, the next few days will be distressing and fraught. As you make your arrangements, try to pack in ways that will allow you to leave campus yourself, rather than requiring family members to assist you. Our goal remains to limit the number of people on campus.
We hope everyone who is able can leave by March 19. We realize you may have logistical questions about packing or storing your belongings; we will post updated information on the student FAQ tomorrow.
*Academic accommodations*. All classes, lectures, seminars, labs, and precepts will move to virtual instruction beginning Monday, March 23rd and remain virtual through the end of Spring 2020, including exams. We realize that some of your coursework will be significantly hampered by this teaching format. We’ll help your instructors accommodate this shift in the best possible way. As we continue remote instruction, we’ll guarantee that you’ll be able to complete your Princeton academic work for the spring semester.
We just this morning urged faculty administering midterm exams to be flexible as we confront this crisis. We asked them, if possible, to:
Administer the midterm exam online, using Blackboard or Canvas;
Allow students to pick up the exam and then take it elsewhere to finish and return it, under the auspices of the Honor Code;
Re-weight the mid-term examination in their grading rubric, to acknowledge student stress and confusion.

To achieve that, we are announcing these measures:
Spring Break is being extended for one week for all students, except for those students in health-related Schools and programs in which Spring Break has already occurred or who are actively engaged in clinical rotations.
In the critically important interest of public health, if at all possible, students who are currently out of town should not return to campus. Students who are on campus should depart effective Sunday, March 15th.
Medical, Dental, Veterinary and some Nursing students will continue their clinical rotations. Information about clinical experiences will be handled separately by the Schools and details will soon be provided in a separate communication from the respective Deans.
Guidance on completion of labs and other non-classroom academic activities for graduate and professional students will be provided by each school. Ph.D. students who are on dissertation status or have completed their coursework will be advised separately in consultation with their graduate deans and the Vice Provost for Education, as we recognize individual research is different from classroom education.
We are actively working with departments and programs at the undergraduate level to ensure comparable academic experiences are provided virtually.
Whether students remain on campus or return home, all classes will be provided by virtual instruction, and on-campus activities will be limited.
