Throat malady is a general term used to describe any illness or infection that affects the throat. Two common throat maladies are strep and CROUP. Strep is an abbreviation for Streptococcal pharyngitis, which is an infection caused by the Streptococcus bacteria. CROUP is an infection of the larynx, trachea, and bronchi, and is most commonly caused by a virus. Both strep and CROUP can cause sore throat, fever, and difficulty breathing. Treatment for both conditions typically includes antibiotics and supportive care.
