The Infectious Disease Epidemiology Section (IDEpi) in the Louisiana Office of Public Health (OPH) has several applications for syndromic surveillance including situational awareness during unusual and/or high profile events, such as the uncharacteristic winter weather Louisiana experienced during the 2017-2018 winter season. December 8th, 2017 saw freezing temperatures with some parts of the state experiencing snow, and January 16- 18, 2018 saw record breaking freezing temperatures throughout the state. Both weather events led to many state office, school and business closures. The freezing temperatures from January 16th -18th led to office closures that lasted longer than the freezing temperatures due to the infrastructure damage the freezing temperatures caused. For example, Orleans parish experienced low water pressure throughout its water systems due to broken pipes following the freeze, leading to boil water advisories. Many people throughout Louisiana had broken pipes at their homes, resulting in flooding and further contributing to low water pressure in some areas. IDEpi used syndromic surveillance to monitor the impacts of the severe winter weather and its aftermath on weather related personal injuries throughout the state.
Objective: The Louisiana Early Event Detection System (LEEDS), Louisiana's syndromic surveillance system, was used to monitor uncharacteristically low temperatures during the 2017-2018 winter season and determine the impact of these temperatures on the number of weather related personal injuries in emergency departments throughout Louisiana.
