BACKGROUND Because risk perceptions can affect protective behavior and protective behavior can affect risk perceptions, the relations between these 2 constructs are complex and incorrect tests often lead to invalid conclusions. PURPOSE To discuss and carry out appropriate tests of 3 easily confused hypotheses: (a). the behavior motivation hypothesis(More)
Poor-quality antimalarial drugs lead to drug resistance and inadequate treatment, which pose an urgent threat to vulnerable populations and jeopardise progress and investments in combating malaria. Emergence of artemisinin resistance or tolerance in Plasmodium falciparum on the Thailand-Cambodia border makes protection of the effectiveness of the drug(More)
BACKGROUND Lyme disease (LD) is caused by the tickborne bacterium Borrelia burgdorferi and, in 2000, accounted for >90% of all reported cases of vectorborne illness in the United States. Aside from anecdotal and indirect evidence, little empirical evidence exists regarding what the U.S. public knows, says, or does about preventing LD. OBJECTIVES To(More)
OBJECTIVES This study examined factors that predispose individuals to protect against Lyme disease. METHODS Knowledge, attitude, and practice questions concerning Lyme disease prevention were included in the Behavioral Risk Factor Surveillance surveys in Connecticut, Maine, and Montana. A total of 4246 persons were interviewed. RESULTS Perceived risk of(More)
In many developing countries, the immunogenicity of three doses of live, attenuated, oral poliovirus vaccine (OPV) is lower than that in industrialised countries. We evaluated serum neutralising antibody responses in 368 children aged 6 months and 346 children aged 9 months in Côte d'Ivoire who had previously received three doses of OPV at 2, 3, and 4(More)
This supplement to the American Journal of Tropical Medicine and Hygiene, entitled “The pandemic of falsified medicines: laboratory and field innovations and policy perspectives,” showcases 17 articles on detection technologies and methods, field surveillance data, multisectorial perspectives, and policy interventions and recommendations needed to create a(More)
Over the past decade, the number of countries reporting falsified (fake, spurious/falsely labeled/counterfeit) medicines and the types and quantities of fraudulent drugs being distributed have increased greatly. The obstacles in combatting falsified pharmaceuticals include 1) lack of consensus on definitions, 2) paucity of reliable and scalable technology(More)
BACKGROUND Some believe that vaccinating young women against human papillomavirus (HPV) will increase their risky behavior. In more formal terms, vaccination lowers risk perception, and people compensate for their lower perceived risk by reducing other preventive behaviors. PURPOSE We test several predictions from the risk compensation hypothesis in the(More)
There is an urgent need for accurate and inexpensive handheld instruments for the evaluation of medicine quality in the field. A blinded evaluation of the diagnostic accuracy of the Counterfeit Detection Device 3 (CD-3), developed by the US Food and Drug Administration Forensic Chemistry Center, was conducted in the Lao People's Democratic Republic.

Mosquitoes can transmit over 100 of the viruses that can cause encephalitis, meningitis, and hemorrhagic disease in humans (Chin 2000; Gubler 1996; Monath 1989). While much is known about the ecology, epidemiology, and clinical manifestations of the arboviral encephalitides (Campbell et al. 2002; Centers for Disease Control and Prevention 1997; Gubler 1998;(More)
