North Central Public Health District says an unusually large number of Gilliam County residents are being diagnosed with and treated for strep throat. Strep throat is an uncomfortable bacterial infection of the throat that occurs mainly in children over two years old. It can occur in adults, but is rare in infants. Strep is easily treated with a number of different antibiotics. The health district recommends if you have a sore throat without the symptoms of a cold, or have been in close contact with someone who has the symptoms of or diagnosed with strep throat, to make an appointment with your health care provider.
