Adam responds: \u201dOf course. I\u2019m the captain of my school\u2019s rugby team.\u201d\n\nFeeling a bit intimidated, you go to take a focused history.\n"}]}

There is no history of travel or exposure to animals.\n\nOn examination, his temperature is 38.9 \u00b0C (102.02 \u00b0F), blood pressure is 110\/70 mmHg, pulse is 72 beats\/min, and respiratory rate is 14\/min.\n\nInspection of the throat shows multiple whitish blotches over enlarged tonsils. There is bilateral tender cervical lymphadenopathy. Cardiorespiratory and abdominal examination is normal.\n"}]}

You then perform a rapid strep test, which is positive.\n\nSubsequently, you obtain throat swab samples for culture. You also prescribe a course of oral penicillin for 10 days, along with analgesics. You then send Adam home, but ask him to come back if he starts feeling worse.\n\n\u0022Well, hopefully, the antibiotics will fix it, Doctor! Thank you so much!\u0022 he says, and leaves the ED.\n"}]}

As expected, they show growth of group A beta-hemolytic Streptococcus (GAS). Since you\u0027ve already started him on penicillin, you make a note in his medical record and ask your staff to follow-up once the course is complete.\n\nHowever, just 2 days afterward, you are surprised to see Adam once again - this time accompanied by his mother. You find out that she is Dr. McGlynn, a very experienced family practice physician.\n\nShe tells you that Adam\u0027s fever and sore throat have persisted since the day you first saw him (a total of 6 days so far). He also developed a rash and abdominal discomfort yesterday.\n\nExamination shows that the tonsils are still enlarged and covered with a white-grayish exudate. Posterior palatine petechiae are also present now. The rash is generalized and maculopapular. Cardiorespiratory examination is normal, but on abdominal examination you detect mild splenomegaly.\n"}]}
