In recent years, Washington State has experienced episodes of degraded air quality from wildfires burning within the state, as well as surrounding states and provinces. Wildfire smoke, particularly the high concentrations of small particulate matter generated by incomplete combustion, can lead to a number of minor as well as significant acute health effects, such as respiratory and cardiac-related issues. As a result, Washington State is developing methodology to monitor syndromic surveillance data for evidence of health impacts across Washington State during ongoing wildfires.

Description
Determine if poor air quality resulting from wildfires could be measured in the general population by monitoring smoke-related respiratory Emergency Department (EDs) visits.

Description
Syndromic surveillance information can be a useful for the early recognition of outbreaks, acute public health events and in response to natural disasters. Inhalation of particulate matter from wildland fire smoke has been linked to various acute respiratory and cardiovascular health effects. Historically, wildfire disasters occur across Southern California on a recurring basis. During 2003 and 2007, wildfires ravaged San Diego County and resulted in historic levels of population evacuation, significant impact on air quality and loss of lives and infrastructure. In 2011, the National Institutes of HealthNational Institute of Environmental Health Sciences awarded Michigan Tech Research Institute a grant to address the impact of fire emissions on human health, within the context of a changing climate. San Diego County Public Health Services assisted on this project through assessment of population health impacts and provisioning of syndromic surveillance data for advanced modeling.
Objective
This presentation describes how syndromic surveillance information was combined with fire emission information and spatio-temporal fire occurrence data to evaluate, model and forecast climate change impacts on future fire scenarios.
Description
In the event of a large-scale public health crisis, successfully detecting and assessing health threats and monitoring population health status over a sustained period of time is likely to require integration of information from multiple sources. In addition, this information must be shared at varying levels of detail both among different agencies or organizations within an affected locality and among response participants at local, state, and federal levels of government. In early 2007, the International Society for Disease Surveillance (ISDS) proposed a project to support member initiated consultations on priority unresolved questions in the field of syndromic surveillance (SS) research, development, or practice. The Duval County Health Department sought and obtained ISDS support to address the use of SS data in combination with other human health and veterinary surveillance data, environmental sampling data, and plume modeling results in the event of an airborne bioterrorist (BT) attack. To date, the development of SS in Florida has mainly focused on systems that monitor information from emergency department (ED) visits. In addition, because SS development was decentralized and managed primarily by county health departments, various systems were used in Florida, including ESSENCE, STARS, EARS and BioDefend.
Objective
The objective of this consultation was to develop expert, consensus-based recommendations for use of SS in combination with other human health, animal health, and environmental data sources to improve situational awareness in the event of a large-scale public health emergency. The consultation, convened by the Duval County, Florida, Health Department, involved other local and state public health offi cials from Florida who addressed this question in the context of a hypothetical BT attack scenario in Duval County. Insights arising from the consultation will be used to strengthen public health surveillance capacities as part of both local and state emergency preparedness efforts in Florida. The approach used by the consultation may be useful to other health departments seeking to enhance their emergency situational awareness capacity.
