Which complications are associated with a GABHS infection?

A GABHS (Group A beta-hemolytic Streptococcus) infection can lead to several serious complications, of which peritonsillar abscess, glomerulonephritis, and rheumatic fever are notable. These complications arise due to the body's immune response to the infection or direct effects of the bacteria.

Peritonsillar abscess occurs as a severe complication of tonsillitis caused by GABHS when pus collects near the tonsils. This can lead to significant pain and difficulty swallowing, and it may require surgical drainage.

Glomerulonephritis is an inflammatory kidney condition that can develop following a GABHS infection, particularly post-streptococcal glomerulonephritis. It can result in symptoms such as hematuria, hypertension, and edema, indicating kidney involvement after infection.

Rheumatic fever is another serious complication that can follow untreated or inadequately treated GABHS pharyngitis. It affects the heart, joints, skin, and nervous system, leading to potentially long-term health issues, particularly rheumatic heart disease.

The other options represent different types of infections and complications often associated with other pathogens or conditions and do not directly relate to GABHS infections in the same significant
