An Ecological Analysis of the Impact of Temperature Inversion on Emergency Department Visits for Respiratory Syndromes and Subsyndromes using BioSense 2.0 Frontend Data

During the winter months, Utah experiences a temperature inversion which traps pollutants, such as fine particle pollution (PM 2.5), in the Salt Lake Valley. A previous study determined the impact of inversion on ED visits for asthma, however similar phenomena have yet to be examined using the BioSense 2.0 syndromic surveillance system. While similar studies utilize a time-stratified case-crossover design, the absence of individually identifiable information on the dashboard precludes the utilization of this methodology.

An Evaluation of Heat-Related Emergency Department Visits Based on Differences in Heat Syndrome Definitions in Northern Illinois

Comparison of heat-related health effects across regions or among different syndromic surveillance systems is problematic due to the lack of a standardized heat-related syndrome definition. While a national standard for common heat-related syndromes would facilitate data comparisons, local customization of syndromes to adjust for unique public health events or characteristics is often necessary to optimize use of syndromic surveillance data.

Assessing the Impact of Climate Change and Land Use Variation on Microbial Transport Using Watershed Scale-modeling

The scientific community accepts that global climate change (CC) will affect the dispersion of microbial organisms in the environment. Risks posed by the transport of these organisms to future communities may be very different than those posed today. A shift in health risks may also be linked to climate driven land-use change, which may alter both microbial loadings to receiving waters and human exposure pathways. Uncertainty surrounding microbial fate and transport renders the assessment of CC effects on waterborne pathogens complex and difficult to forecast.

Environmental Public Health Tracking: Success Stories from a Collaborative Surveillance System

Understanding how exposure to hazards in our environment (air, water, food and surroundings) affects our health is critical to understanding causes of many chronic and acute diseases and to planning and implementing appropriate response and prevention efforts.

Detecting Public Health Impacts Associated with Air Pollution Events in the UK Using Syndromic Surveillance

Air pollution is well documented to cause adverse health effects in the population. Epidemiological/toxicological studies have demonstrated that air pollution is associated with various adverse health outcomes, ranging from mortality to subclinical respiratory symptoms. Classical epidemiological studies of the health effects of air pollution are typically retrospective. In order to assess the effectiveness of any public health messages or interventions in a timely manner there is a need to be able to systematically detect any health effects occurring in real-time.

Surveillance of Heat-related Morbidity: Relation to Heat-related Excess Mortality

The impact of heat on mortality is well documented but deaths tend to lag extreme heat and mortality data is generally not available for timely surveillance during heat waves. Recently, systems for near-real time surveillance of heat illness have been reported but have not been validated as predictors of heat related mortality. In this study, we examined the associations among weather, indicators of heat-related ambulance calls and emergency department visits and excess natural cause mortality in New York City.

Using Google Dengue Trends to Estimate Climate Effects in Mexico

The incidence of dengue fever (DF) has increased 30 fold between 1960 and 2010. The literature suggests that temperature plays a major role in the life cycle of the mosquito vector and in turn, the timing of DF outbreaks. We use real-time data from GDT and real-time temperature estimates from NASA Earth observing systems to examine the relationship between dengue and climate in 17 Mexican states from 2003–2011. For the majority of states, we predict that a warming climate will increase the number of days the minimum temperature is within the risk range for dengue.

Utilization of Various Data Sources to Locate West Nile Clusters in Tulsa County

As the summer temperatures soared to their highest ever recorded, Oklahoma experienced its highest disease count ever since the disease had been discovered in New York in 1999. Tulsa County is the second most populous county in Oklahoma and accounted for over one-fourth of the West Nile Cases in Oklahoma. Tulsa City County Health Department is also the only funded mosquito control program in the state that regularly reports to CDC’s AborNet.



Identify, analyze, and summarize WNV in Tulsa County, Oklahoma.

When it Rains it Pours: Real-time Situational Awareness for Two Weather Emergencies in Connecticut

On August 28, 2011 Tropical Storm Irene made landfall in Connecticut. On October 29, 2011 Connecticut was impacted by Winter Storm Alfred. Both of these storms included high winds and heavy precipitation which resulted in prolonged power outages, disruption of public drinking water systems, property damage, and widespread debris throughout the state. The Hospital Emergency Department Syndromic Surveillance (HEDSS) System was utilized to provide real-time situational awareness during the response and recovery phases of both storm events.

Utility of Syndromic Surveillance for Investigating Morbidity Resulting from a Severe Weather Event

On 12/14/06, a windstorm in western Washington caused 4 million residents to lose power; within 24 hours, a surge in patients presented to emergency departments (EDs) with carbon monoxide (CO) poisoning. As previously described, records of all patients presenting to King County EDs with CO poisoning between 12/15/06 to 12/24/06 (n=279) were abstracted, of which 249 met the case definition and eligibility requirements.
