Geographical distribution of the index subdistricts (red pinpoints) and the destination subdistricts with different risk levels, based on R0 = 5 (β = 0.5, γ = 0.1). The risk level was categorized as ‘High’ (greater than 9.55 × 10− 4), ‘Medium’ (greater than 2.13 × 10− 4 to 9.55 × 10− 4), ‘Low’ (greater than 0 to 2.13 × 10− 4), and ‘No risk’ (risk = 0). a. The identified subdistricts are illustrated on the map of Thailand, b. A magnified map focusing on the northern part of Thailand and, c. A magnified map focusing on the central plain of Thailand where both index and destination subdistricts are concentrated (the figure was originally created)
