1. Sanghlaburi, western Thailand
Established in 1999
Malaria Study

Lethal ovitrap testing, to include identification and selection of compounds that will attract mosquitoes to the ovitrap are performed. The lethal ovitrap attracts egg-laying Aedes mosquitoes (the vectors of dengue) into a container where they are exposed to a lethal dose of an insecticide. Evidence obtained in this study indicated that the lethal ovitrap provided significant control of Aedes aegypti.

New associations between chiggers, rodents, and Orientia tsutsugamushi in active rice agricultural areas, an ecological habitat not previously known to support scrub typhus, continued to be researched and validated.

2. Various Thai Provincial Hospitals
Continued evaluation of the current risk of scrub typhus at Thai hospitals.
