1 Drug Resistance Monitoring in Cambodia

2 Sensitivity (S or S/RI) at 4 sentinel sites 1991 – 97 Western areas: Battambang, Pursat, Eastern areas:Ratanakiri, Kratie  Chloroquine (West): S or S/RI = 3-12% (East): S/RI = 76%-86%  Fansidar® (West): S or S/RI = 0-13% (East): S or S/RI = 57-80%  Quinine and Tetracycline (All areas):S/RI = 100 %  Mefloquine monotherapy: (West): S or S/RI = 80%-97% (East): S or S/RI = 100%

3 Drug Resistance Monitoring in Cambodia 1998  No study  Lack of budget  Lack of human resources due to Dengue due to Dengue epidemic outbreak

13 Sentinel sites of drug resistance monitoring in Cambodia

14 Conclusion The result showed the sensitivity of A+M still high (ACPR = 92 – 100%) each sentinel site if we compared to the result of previous study. So The A+M can be continue as drug for our first line treatment of malaria.
