Alvarez-Hernandez G, et al. - In a cross-sectional study, conducted with 343 physicians working in medical facilities in Sonora, Mexico, researchers explored physician knowledge of clinical, epidemiological and preventive aspects of Rocky Mountain spotted fever (RMSF). Only 62% of physicians agreed that for children under 8 years with suspected RMSF, doxycycline should be used as the first choice treatment. In addition, only 40% of primary care physicians correctly identified the time to initiate doxycycline, and 32% correctly identified the case-fatality rate of untreated RMSF in all patients. They supported educational programs that improve the risk perception and medical knowledge about RMSF targeting at physicians most likely to have initial contact with diseased patients.
