Can GIS be used to track disease?
The CDC tracks disease by focusing on place and space—the geographic location of the problem. Officials use maps to visualize and analyze where and why outbreaks occur and where people are seeking healthcare. By using a geographic information system (GIS), they can store, analyze, model, and display all relevant data.
What are the 4 major disease vectors?
Disease vectors
- Malaria (protozoan): Anopheles species of mosquito.
- Lymphatic filariasis (nematode worm): Culex, Anopheles, Aedes species of mosquito.
- Dengue (virus): Aedes species of mosquito.
- Leishmaniasis (protozoan): mainly Phlebotomus species of sandfly.
What are 3 examples of vectors of disease?
Vector-borne diseases are illnesses that are transmitted by vectors, which include mosquitoes, ticks, and fleas. These vectors can carry infective pathogens such as viruses, bacteria , and protozoa , which can be transferred from one host (carrier) to another.
How GIS is used in public health?
GIS has continued to be used in public health for epidemiological studies. By tracking the sources of diseases and the movements of contagions, agencies can respond more effectively to outbreaks of disease by identifying at-risk populations and targeting intervention.
How is GIS data used?
A geographic information system (GIS) is a computer system for capturing, storing, checking, and displaying data related to positions on Earth’s surface. GIS can use any information that includes location. The location can be expressed in many different ways, such as latitude and longitude, address, or ZIP code.
What is the most common vector-borne disease?
In the United States, the most common vectorborne pathogens are transmitted by ticks or mosquitoes, including those causing Lyme disease; Rocky Mountain spotted fever; and West Nile, dengue, and Zika virus diseases.
Is Ebola a vector-borne disease?
Additionally, Ebola virus is not known to be transmitted through food. However, in certain parts of the world, Ebola virus may spread through the handling and consumption of wild animal meat or hunted wild animals infected with Ebola. There is no evidence that mosquitoes or other insects can transmit Ebola virus.
What are the examples of disease vector?
Vector-Borne Disease: Disease that results from an infection transmitted to humans and other animals by blood-feeding anthropods, such as mosquitoes, ticks, and fleas. Examples of vector-borne diseases include Dengue fever, West Nile Virus, Lyme disease, and malaria.
What kind of data is in a GIS?
For example, cases of disease, hospitals, roads, waterways, country boundaries, and health catchment areas are all types of spatial data. In a GIS, the data usually include attributes, or descriptive information.

What does GIS stand for at the CDC?
GIS and Public Health at CDC. Geography is the study of how the world differs from place to place. Geography uses a spatial, or geospatial perspective, meaning it focuses on place and space, looking at what, where and why phenomena occur. Here at the CDC, we study the spatial aspects of health and illness.
What can a GIS do for a hospital?
The descriptive data also allows you to search and display associated attributes (e.g., number of hospital beds, types of specialized services offered, etc). In terms of analysis, a GIS offers the opportunity to use spatial data to answer questions.
