|Proximity to index patient|
|Within 1 m during time he was sick at home||8 (89)||12 (57)||4.0 (0.6–27.8)|
|Within 1 m every day||7 (78)||9 (43)||3.1 (0.8–12.4)|
|Within 1 m on day preceding hospitalization||7 (78)||11 (52)||2.3 (0.6–9.3)|
|Visited index patient in the hospital||6 (67)||10 (48)||1.8 (0.5–5.7)|
*Bold indicates statistical significance. This household transmission analysis included relatives >14 y of age living in the 4 households of the index patients, defined as the first patient in the household who received a MERS-CoV diagnosis by rRT-PCR. Secondary transmission is defined as onset of illness or testing positive for MERS-CoV after the household’s index patient had received a diagnosis. Two MERS-CoV–infected household members were excluded from analysis because they had illness onsets before the presumed household index patient’s illness and were subsequently reported to have MERS-CoV antibodies. MERS-CoV, Middle East respiratory syndrome coronavirus; rRT-PCR, real-time reverse transcription PCR.
