Estimated range of Aedes albopictus and Aedes aegypti in the United States, 2017

CDC has updated the estimated range maps for Ae. aegypti and Ae. albopictus mosquitoes by using a model that predicts possible geographic ranges for these mosquitoes in the contiguous United States. The model used county-level records, historical records, and suitable climate variables to predict the likelihood (very low, low, moderate, or high) that these mosquitoes could survive and reproduce if introduced to an area during the months when mosquitoes are locally active. Maps are not meant to represent risk for spread of any specific disease

Syndromic surveillance of air pollution incidents across international borders

The impact of poor air quality (AQ) on human health is a global issue, with periods of poor AQ known to occur in multiple locations, across different countries at, or around the same time. The Public Health England (PHE) Emergency Department Syndromic Surveillance System (EDSSS) is a public health legacy of the London 2012 Olympic and Paralympic Games, monitoring anonymised daily attendance data in near real-time from a sentinel network of up to 38 EDs across England and Northern Ireland during 2014.

Application of GIS for Optimization of Epidemiological Monitoring

Technology that combines traditional manipulations with databases and complete visualization of geographic (spatial) analysis employing maps has been developed in order to explore the possibilities for Geographical Information Systems (GIS) to be used in sanitary and epidemiological surveillance system based on the analysis of morbidity and identification of influence of hazardous chemical environmental factors on human health.

Detecting and Investigating a Large Community Outbreak of Legionellosis — South Bronx, July 2015

We will present an overview of: (1) the epidemiology of Legionnaires’ disease (LD), (2) techniques applied by the New York City (NYC) Department of Health and Mental Hygiene for routine LD surveillance and outbreak investigation, (3) detection and investigation of the second largest community-acquired LD outbreak in the U.S (South Bronx, July 2015), and (4) recent legislation enforcing regular maintenance, testing, and mediation of NYC cooling towers.

Real-Time Surveillance of Environmental and Demographic Data in Ontario with PHIMS

Geographic Information System (GIS) applications are increasingly being used for public health purposes. GIS technology provides visual tools – through the creation of computerized maps, graphs, and tables of geographic data – that can assist with problem solving and inform decision-making. PHIMS aims to enable visualization and spatial analysis of environmental data with underlying population based indicators.

Weather Outlook: Cloudy with a Chance of...— Classification of Storm-Related ED Visits

Hurricane ‘Superstorm’ Sandy struck New Jersey on October 29, 2012, causing harm to the health of New Jersey residents and billions of dollars of damage to businesses, transportation, and infrastructure. Monitoring health outcomes for increased illness and injury due to a severe weather event is important in measuring the severity of conditions and the efficacy of state response, as well as in emergency response preparations for future severe weather events.

Analysis of Healthcare Seeking Behavior

Healthcare seeking behavior is important to understand when interpreting public health surveillance data, planning for healthcare utilization, or attempting to estimate or model consequences of an adverse event, such as widespread water contamination. Although there is evidence that factors such as perceived susceptibility and benefits affect healthcare seeking behavior, it is difficult to develop accurate assumptions due to a lack of published research on this topic. Current conceptual behavior models, such as the health belief model, are not easily translated into quantifiable terms.

Dry Climate as a Predictor of Chagas; Disease Irregular Clusters: A Covariate Study

Chagas’ disease, caused by the protozoan Trypanosoma cruzi, is spread mostly by Triatominae bugs. High carbon dioxide emission and strong infra-red (IR) radiation are indicative of their presence. Periods of low atmospheric water saturation favor their dispersal, when the bugs’ IR perception is high.

Carbon Monoxide Poisoning during Hurricane Sandy in Affected New York State Counties

CO poisoning is a leading cause of mortality and morbidity in disaster and post-disaster situations, when widespread power outages most likely occur (1, 2). The NYSDOH Syndromic Surveillance System receives daily ED visit chief complaint data from 140 NYS (excluding New York City) hospitals. Daily power outage data are available from the NYS Department of Public Service (NYSDPS). These data can be used to estimate the risk of CO-EDs and provide useful information for public health situational awareness and emergency response management during disaster events.

Environmental Health Surveillance: A Critical Function of Public Health Laboratories

Canada experienced 92 waterborne diseases outbreaks between 1975 and 2001. In addition, at any one time about 1500 communities in Canada are unable to use their drinking water. The source of exposure in disease outbreaks is often not known, so the true disease burden attributable to water related exposure may be much higher. Researchers have investigated risk factors for waterborne disease. However, providing acces to surveiallance tools of use by frontline staff in the field as well as by surveillance professionals was key to making this type of system successful.
