Why illness spreads fast in dorms — and how to stay healthy

College dorms may be a rite of passage, but they are also a hotspot for mold and illness.
To set yourself or your college student up for a successful and healthy school year, it’s important to consider some health essentials.
“Germs spread fast in dorms because of the many residents living in close quarters,” explains Dr. Huma Khan, an adolescent medicine physician at Advocate Children’s Hospital. “On top of it, many of these students experience poor sleep, stress and may be lacking proper nutrition which further weaken immune defenses.”
Common dorm illnesses include cold, flu, strep and mono.
To limit the spread of germs, Dr. Khan recommends:
- Washing your hands often
- Getting up-to-date flu and COVID vaccines
- Disinfecting shared surfaces
- Never sharing utensils, makeup or drinks
- Resting and staying home if you are sick – doing your best to socially distance from roommates
If you are experiencing coughing, congestion, headaches or itchy eyes that won’t seem to go away, it may be a different dorm culprit: mold.
“Dorms are the perfect breeding ground for mold,” says Dr. Khan. “To reduce your exposure, add an air purifier, microfiber towels, HEPA vacuums and EPA-approved products to your dorm packing list.”
Other ways to prevent mold exposure in dorms:
- Wipe spills immediately
- Hang up wet items like towels and clothes
- Keep humidity between 35% to 50%
- Run exhaust fans or crack a window during showers
- Avoid frequent temperature changes that may cause condensation
- Clean your AC unit monthly
- Report mold to dorm maintenance
Despite taking precautions, you may still get sick, which can be scary and overwhelming if you are away from home for the first time. To calm your anxiety and to ensure a smooth first visit, check out the college’s student health services and identify your new local pharmacy.
