Analysis of international traveler mobility patterns in Tokyo to identify geographic foci of dengue fever risk

Table 3 Agreement analysis between visit destinations of international travelers from countries/regions with or without dengue

Comparison pairs	P_a	P_b	Kappa	AC1
Countries with continuous transmission vs sporadic cases only	0.68	0.46	0.39	0.39
Countries with continuous transmission vs regional (localized) transmission	0.78	0.46	0.57	0.57
Countries with sporadic cases only vs regional (localized) transmission	0.83	0.64	0.58	0.72

Countries were divided into: (i) Group 1 countries with continuous risk of dengue transmission (n=9 among all countries with international mobile phone user records in Japan), (ii) Group 2 countries with occasional outbreaks in some regions (regional transmission) (n=4), and (iii) Group 3 countries with only sporadic cases (n=38). The agreement values of P_a, P_b, kappa and AC1 were calculated according to the distributions of geographic meshes visited by travelers. The numbers of meshes visited by travelers from each group of countries/regions were counted for further agreement analyses
