Yes, it is possible to have strep throat without a fever. While fever is a common symptom of strep throat, some individuals, especially adults or those with a strong immune system, may have strep throat without developing a fever. Strep throat symptoms can include a sore throat, swollen lymph nodes, white patches on the tonsils, tiny red spots on the roof of the mouth, and difficulty swallowing. The only definitive way to diagnose strep throat is by a throat swab test, such as a rapid strep test or throat culture. If a person has a persistent sore throat or other symptoms even without a fever, it is important to seek medical evaluation and testing because untreated strep throat can lead to complications. Treatment generally involves antibiotics once confirmed by testing.
