streptokokkifaryngitis

Streptococcal pharyngitis, commonly known as strep throat, is a bacterial infection caused by Streptococcus pyogenes, also known as group A Streptococcus. It primarily affects the pharynx, the part of the throat behind the mouth and nasal cavity. The infection is characterized by a sudden onset of sore throat, which may be severe, and difficulty swallowing. Other common symptoms include fever, red and swollen tonsils, sometimes with white patches or streaks of pus, and tiny red spots on the roof of the mouth called petechiae. Swollen lymph nodes in the neck are also frequently observed.

Strep throat is highly contagious and spreads through respiratory droplets when an infected person coughs, sneezes, or talks. Close contact with an infected individual or touching contaminated surfaces and then touching one's face can also lead to transmission. Diagnosis is typically made through a rapid strep test or a throat culture performed by a healthcare professional. Prompt diagnosis and treatment are important to prevent complications.

Antibiotics, usually penicillin or amoxicillin, are the standard treatment for strep throat. Antibiotic therapy helps to reduce the duration of symptoms, prevent the spread of infection, and significantly lower the risk of developing serious complications such as rheumatic fever, which can affect the heart, joints, brain, and skin, and post-streptococcal glomerulonephritis, a kidney disorder. It is crucial to complete the full course of antibiotics as prescribed by a doctor, even if symptoms improve quickly.
