If you are experiencing diarrhea, vomiting, a fever combined with a sore throat, or yellowing of your skin or eyes, you should:
B) Notify your local health department.
You should notify your local health department because you are obviously very sick, and should not go to work, because it could spread. You should never not tell anyone that you don't feel well, because you could throw up during work. You should also never work in food preparation areas, because you could potentially contaminate the food.
