MCQ IN MEDICINE

Detailed explanation-1: -Inadequate or lack of antibiotic treatment of streptococcal pharyngitis increases the risk of someone developing acute rheumatic fever. In approximately one-third of patients, acute rheumatic fever follows subclinical streptococcal infections or infections for which medical attention was not sought.

Detailed explanation-2: -What Causes Impetigo? Two types of bacteria-Staphylococcus aureus and group A streptococcus (which also causes strep throat)-usually cause impetigo. Methicillin-resistant Staphylococcus aureus (MRSA) is also becoming an important cause of impetigo.

Detailed explanation-3: -When left untreated, the symptoms of group A strep pharyngitis are usually self-limited. However, acute rheumatic fever and suppurative complications (e.g., peritonsillar abscess, mastoiditis) are more likely to occur after an untreated infection.
