Hypochondriacs rejoice! Who Is Sick? is a website that allows you to tell the world about your symptoms, or search if your neighborhood is a hotbed for runny nose, skin sores, or even bloody stool.
Right now, I'm really sorry to see someone in my neighborhood battling runny nose, stuffy nose, sneeze, headache, dizziness, muscle ache, stomachache, nausea, vomiting AND diarrhea!
