Imported Measles and Implications for Its Elimination in Taiwan
Figure 1. A) Timetable of 53 measles cases reported in Taiwan from week 45 of 2008 to week 21 of 2009. Each cell in the timetable represents 1 case; each case is identified with an identification number followed by a letter that represents the hospital (uppercase) or clinic (lowercase) that reported the case. Cases 1–8, 9–21, 22–24, 25–33, 34–35, 36–45, 46–48, and 49–50 belong to clusters 1 through 8, respectively, and cells within a cluster are the same color. Cases 51–53 were from 3 sporadic cases and are not colored. The case numbers peaked during the eighth week of 2009, with 8 cases distributed through northern (hospital D), central (hospital E), and southern (hospitals F and P) Taiwan; these cases originated from 4 importation chains.
