Armed Forces Research Institute of Medical Sciences Background AFRIMS started doing surveys for malaria prevalence and drug resistance patterns surveys in the Sangkhlaburi district in 1995AFRIMS started doing surveys for malaria prevalence and drug resistance patterns surveys in the Sangkhlaburi district in 1995 Testing an antibiotic, azithromycin:Testing an antibiotic, azithromycin: for prevention of malaria in 1996;for prevention of malaria in 1996; for treatment of PF with quinine in for treatment of PF with quinine in Started an relationship with Kwai River Christian HospitalStarted an relationship with Kwai River Christian Hospital What is causing the other 70% of fevers at the hospital?What is causing the other 70% of fevers at the hospital?

Armed Forces Research Institute of Medical Sciences Objectives To define the specific cause of undifferentiated febrile illnesses: To identify specific rickettsial, arboviruses and zoonotic pathogens. To identify the patterns of drug resistance of diarrheal pathogens and enteric fevers (typhoid) Evaluate the prevalence of these illnesses by sero-surveys of the local populations To evaluate test kits for rapid diagnosis of undifferentiated febrile illnesses as compared to standard diagnostics. Study approved by Committee on Research in Humans Subjects, MOPH
