Telling the difference between run-of-the-mill sore throat caused by a virus, which doesn’t require medication, from bacteria-caused strep throat, which should be treated with antibiotics, is a tricky thing at any age. Physicians from Harvard Medical School, MIT, and the Skaggs School of Pharmacy in California have come up with a scoring system that could save adults a trip to the doctor for what would most likely turn out to be a garden variety sore throat (it hasn’t been tested in kids yet). It’s based on symptoms, age, and the percentage of people in your area who have tested positive for strep within the last two weeks. If your score is high, then head to your doctor’s office. If it indicates that you are unlikely to have strep, there’s little need for you to rush in for an exam or throat culture. The researchers estimate that use of this kind of score could prevent 230,000 office visits in the United States each year and keep 8,500 men and women from getting antibiotics they don’t need.
