   The National Retail Data Monitor (NRDM) monitors sales of over-the-counter (OTC) healthcare products to identify disease outbreaks as early as possible.  The goal of the NRDM project has been to bring this new type of public health surveillance into existence as quickly as possible to meet the nationís need for the early detection of bioterrorism as well as naturally occurring disease outbreaks.

    Since its activation with public health departments in December 2002, the number of retail pharmacy, grocery, and mass merchandise operations that participate in the NRDM has grown to more than 21,000 stores, from among the nation's top thirteen chains. More than 800 public health officials, across 49 states, the District of Columbia, and Puerto Rico, have had access to the system via protected user accounts



Access to the National Retail Data Monitor is available to public health officials solely for the purpose of public health surveillance. For specific information, call or email the Program Manager of the NRDM (see Contact information).  


Further information for data providers and other interested parties is provided in the NRDM Fact Sheet [PDF] and in publications.
