ILI; zoonoses; correlation; multistream; weather Introduction Syndromic surveillance of ED and PCC data has been widely used for the detection, tracking and monitoring of health events (e.g., bioterrorism, disease outbreaks and environmental exposures) over the past decade (1) . In recent years, these data have been found to be useful for public health programs not normally associated with syndromic surveillance (e.g., injury prevention, drug abuse and environmental health (1)). In 2010, the first calls referencing exposure to products marketed as 'legal highs' and 'bath salts' were received by PCCs in the United States (2) . Synthetic drugs, such as those commonly known as bath salts, often are labeled as 'not for human consumption' and, thereby, circumvent normal legal control procedures that control the sale and distribution of recreational drugs (3) . The purpose of this study was to evaluate the emerging trends for the use of bath salts in Ohio.
