Fig. 4From: Risk of MERS importation and onward transmission: a systematic review and analysis of cases reported to WHOCase history of MERS importations. Cases are aligned to the beginning of the infectious risk period, i.e. the most recent between the importation date and the date of symptoms onset. Days in the infection risk period are color-coded according to the patientās history, ending with isolation (dark red) or death (black). Importation events are sorted by duration of the infection risk period. Where no information was available on time of isolation, we assumed infection risk period to end with case confirmation. A box is used to highlight cases that led to secondary transmissionBack to article page
