Strep throat is a bacterial infection caused by group A Streptococcus bacteria, and it can last for about 3 to 7 days with appropriate treatment. However, if left untreated or inadequately treated, strep throat can last longer, and the symptoms may become more severe.
The typical treatment for strep throat is a course of antibiotics prescribed by a healthcare provider. If antibiotics are taken as prescribed, the infection should start to improve within a day or two, and symptoms should resolve completely within a week. It is important to complete the full course of antibiotics, even if symptoms improve, to ensure that the infection is completely eradicated.
If symptoms persist for longer than a week or if they become more severe, it is important to see a healthcare provider again to rule out any complications or the possibility of a different underlying condition.
