Figure 3. Reported contact among family members who received a MERS-CoV diagnosis and illness onset timeline, Al-Qouz, Saudi Arabia, 2014. Patients L, M, and N, as well as the infected nurse, reported no or mild symptoms and could not identify onset dates; for these 4 persons, the rRT-PCR–positive date is listed. All persons were questioned about ill family members with whom they had close contact during illness. Solid arrows indicate contact between persons within 14 days (MERS–CoV incubation period is <14 days) and indicate a likely infection source. Dashed arrows indicate contact after the 14-day incubation period; they are included for patients M and N because these patients could not identify their precise illness onset dates. MERS-CoV, Middle East respiratory syndrome coronavirus; rRT-PCR, reverse transcription PCR.
