Is getting strep without tonsils possible? Yes. Strep throat is caused by bacteria that can live in the nose and mouth, spread through saliva or contact with contaminated surfaces. Strep throat symptoms include sore throat, pain when swallowing, fever, red/swollen tonsils, and swollen lymph nodes. Tonsillitis and strep throat are different. Strep throat is caused by bacteria, while tonsillitis can be caused by bacteria or a virus. If you think you have tonsillitis or strep throat, visit an urgent care center for diagnosis and treatment.
