*Bold indicates statistical significance. Analysis includes all relatives 14 y of age tested for MERS-CoV (n = 59), regardless of household or visitor status. Positive indicates positive rRT-PCR or serologic antibody testing for MERS-CoV; negative indicates negative rRT-PCR and serologic antibody testing. Children (one 2-year-old rRT-PCR–positive child and 19 rRT-PCR–negative children) were excluded because they did not have serologic antibody testing. Listed chronic medical problems were self-reported; no one reported chronic lung or kidney disease, and other self-reported problems (hyperthyroidism, allergies, and solitary kidney) were excluded. MERS-CoV, Middle East respiratory syndrome coronavirus; rRT-PCR, real-time reverse transcription PCR.
†Ages were as follows: MERS-CoV positive: median 37 y (range 16–73 y); MERS-CoV-negative: median 25 y (range 14–60y).
