Scarlet fever - A retrospective case series in the midst of recent upsurge of cases in India.

Scarlet fever, caused by Group A Streptococcus [Streptococcus pyogenes], presents with a characteristic red rash, fever, and pharyngitis. It predominantly affects children aged 5-15 years, although individuals of any age can be affected. Transmission occurs via respiratory droplets and direct contact with contaminated surfaces or infected individuals. This study emphasizes the utility of rapid antigen detection tests [RADT] as point-of-care diagnostics for scarlet fever, particularly in the context of the recent rise in cases in India. Early diagnosis and initiation of appropriate antibiotic therapy are critical to preventing complications such as acute rheumatic fever and renal involvement.
