Map of pneumonic plague outbreak (n = 14) in the commune of Ampasipotsy Gara in Moramanga, Madagascar, 2015. The index case-patient (case-patient 1) was infected with Yersinia pestis at Antsahatsianarina and spread the bacterium to Beravina (burial site of case-patient 1), Ambilona (case-patient 10’s home), and Ambatoharanana (burial site of case-patient 2 and home of case-patient 14). Each pie chart indicates the proportions of plague cases (red), seropositive contacts (blue), seronegative contacts (green), unsampled contacts (yellow), and noncontacts (brown) among the total inhabitants of each site. Pie chart details are given in the Technical Appendix).
