Strep throat tends to occur most often in children between 5 and 15 years old. But can infants get strep throat? The answer is yes -- strep throat can affect anyone, including infants, young children, and adults. However, it can often be challenging to diagnose strep throat in infants and younger children because they do not always have the classic signs of this throat infection. Instead, they have more uncharacteristic symptoms.
Common symptoms of strep throat in children and adults include: 1  Severe and sudden sore throat without coughing, sneezing, or other cold symptoms. 2  Pain or difficulty with swallowing. 3  Fever over 101Â°F (38.3Â°C) . 4  Lower fevers may point to a viral infection and not strep.
