What to do

  • Wear a mask around roommates
  • Ask your campus health center about antiviral medicine early, within the first 2 days
  • Get a flu shot next season

Getting around while sick at MIT

MIT runs on problem sets and lab hours, so the question is often whether to push through or rest.

You may be riding the Red Line at Kendall/MIT. Stay off crowded trains while you have a fever. If you must travel, wear a mask.

Living situation at MIT

MIT undergraduates live in dorms and in fraternities, sororities and independent living groups, so illness can move through a floor or house quickly. Stay in your room, wear a mask around roommates and keep your own towels and cups.

Care near MIT

Your first stop is usually MIT Medical. Call or check its website for hours and how to be seen. For emergencies, Mount Auburn Hospital in Cambridge or a Boston hospital across the Charles River or call 911. Pymander is free to text and is not affiliated with MIT.

When to get help right away

Trouble breathing, chest pain, confusion, a stiff neck with fever, or being unable to keep fluids down are reasons to go to urgent care or the ER, or call 911.
