*LD, Lan Dokmai; NB, Na Bo Kham; NC, Nakhon Chum; NP, Nong Pling; SK, Sa Kaeo; TN, Thep Nakhon. †Households are described by their subdistrict, cluster, and house numbers, such that the first 2 letters denote subdistrict, the next 2-digit number denotes cluster, and an H followed by a 3-digit number denotes house number. ‡Two persons from the donor household were dengue virus–positive 2 weeks apart.‡
