Most colleges make people sick. It’s a massive hub of people sharing a lot of the same spaces. Many of which are nasties that don’t even do basic hand washing. My first college I had tonsillitis nonstop until I changed dorms. Never had it again. Second college had a “virus” named after the school because it would sweep the masses pretty frequently. It’s pretty typical and standard. Anywhere there’s lots of people there’s lots of germs and sickness and easier to spread.
