Germs are hitting OCU hard, and students are feeling the pinch of sick days at the start of the semester.Currently, several strains of illness are criss-crossing the OCU campus, including influenza, strep, mono, the common cold, and stomach bugs. While the more mild forms of these diseases can be treated with rest, lots of fluids, and over-the-counter medicine to control symptoms, the other diseases are very serious and should be treated by a medical professional.
