USAID DART on Cholera in Goniaves

               Experienced professionals come together to form Disaster Assistance Response Teams (DARTs) dedicated to saving lives, alleviating suffering, and reducing the social and economic impact of disasters. DART teams were sent to Haiti after the massive 7.0 earthquake in early 2010.

              An offical report from USAID gives an update on DART's performance in Haiti. Click here to see report.

              Because Haiti's water supplies became contaminated by the aftermath of the quake, a Cholera epidemic brokeout in Haiti. They maps below shows the numbers of Cholera outbreaks as well as treatment centers as well as humanitarian assistance.

           

Intro to Spatial Epidemiology

Spatial epidemiology is the study of spread of disease and disease transmission. Understanding how diseases spread helps to reduce outbreaks and control future spread as well as aiding in resource allocation. Medical geography is a part of medical research that utilizes techniques of the geographic field, such as GPS, GIS, modeling, and cartography, to assist in the study of global health and the spread of diseases. This area of geographic study investigates the impact of climate and location on both the health of an area’s population and on the health of the individual (Goodchild, 2010).

                Why is disease mapping relevant today? Because many factors control how disease outbreaks begin and are spread. Natural disasters and weather events often have strong effects on disease spread and realizing this relationship can lead to prevention and better preparation by local and state officials. The environment affects our health and understanding environmental factors can lead to a better understanding of disease spread and causation. These factors, as well as people, are spread, often unevenly, across varying geographic regions (Cromley, 2002).
