The First Vector Borne Disease Surveillance Workshop
On June 8 & 9, 2019, twelve pacific island public health professionals met in Honolulu, HI to participate in a Community Health Maps training specifically designed to demonstrate how to collect and work with geographic data related to vector borne diseases, i.e. those that are transmitted to humans via other animals such as mosquitoes. Attendees represented: American Samoa, the Federated States of Micronesia, Guam, the Commonwealth of the Northern Mariana Islands, the Republic of the Marshall Islands and the Republic of Palau.This was the first of two, two-day, workshops aimed specifically at tackling the spread of diseases like Dengue fever, West Nile and Zika viruses. It was a team effort. The training was organized by the Association of State and Territorial Health Officials (ASTHO). Participants attendance was funded by CDC’s National Center for Environmental Health. Travel for the trainers was funded by the National Library of Medicine, (funding for the workshop is provided under a sub-award from the National Library of Medicine to ICF International). This particular CHM workshop was taught in conjunction with ASTHO’s Insular Area Climate and Health Summit.After an introduction to the Community Health Maps project - it's origins, workflow and examples of past projects - participants learned to create a data collection form and use their smartphones to map features (trees, signs, benches etc...) around the 
conference site using Fulcrum. Participants saw how this particular part of the workflow could be applied in their home regions to digitally locate areas of standing water and/ or sand pits that are some examples of breeding habitat for mosquitoes. Others anticipated mapping salt water resistant taro, households where infections have occurred and other geographic factors that contribute to the spread of vector borne diseases.For the remainder of the first day the group took the data they created earlier and imported into QGIS, a sophisticated geographic visualization desktop software. In this section they became familiar with QGIS and how to symbolize layers and make a print map.In addition to the data collected on site, we worked with mosquito data acquired courtesy of Dr. Chris Barker covering Madera County, CA. The data included mosquito trap results over five years, virus testing, mosquito biting complaints, storm drains, parcel boundaries, roads and a hypothetical case of Dengue fever.
The second day focused on generating vector borne disease surveillance products. Kurt Menke developed a curriculum to demonstrate how a GIS can create maps and statistical charts that transform simple text and numbers in a database into intuitive graphics that communicate information quickly and accurately. The previous blog post has more detail about the specific vector borne disease surveillance products participants learn to create.
The attendees had a wide range of GIS skills from introductory to advanced capabilities. We experienced many of the common technical difficulties when working in a hotel conference room, older and newer computers and variations with different operating systems (Windows and Macs) as well. Despite all the differences, all of the participants: A) collected data with their smartphones, B) exported their data to a desktop GIS, C) used prepared data to create geographically accurate statistics, D) generated heatmaps of mosquito populations, E) calculated the minimum infection rate per year for West Nile and St. Louis Encephalitis viruses, F) identified potential sources using buffer operations with distances specific species are know to be able to travel, G) identified parcels at risk due to their proximity to a fictional outbreak of Dengue Fever and H) generated trend graphs of mosquito populations through time via the QGIS Data Plotly plugin. All participants received official QGIS certificates.The skills required to complete these tasks are not always simple and straight forward. The participants of this workshop expressed great enthusiasm and persistence in figuring it all out... making mistakes and trying again. Many expressed a need for more training and a desire to have more specialized trainings on site specifically related to projects they are already working on.The second workshop in the series will be taught next week in Providence, RI at the GIS Surveillance Workshop. This will be attended by State based health officials.This vector borne disease surveillance version of the Community Health Maps workflow showcases the analysis and data visualization capabilities of QGIS, as well as, the data collection capabilities of Fulcrum. It represents perhaps the greatest potential for applied use of Community Health Maps to date.These workshop materials will part of the suite of https://communityhealthmaps.nlm.nih.gov/resources/ available through the Community Health Maps program in the near future.If you are interested in having this taught for you or your colleagues contact Kurt Menke (kurt@birdseyeviewgis.com)
This workshop represents applied real-world workflows. These are many of the standard products needed by public health officials and typically produced by researchers. Having this sort of analysis and data visualization available via an open source package means anyone willing to take a few days to learn can produce them! This is especially true as the needed input data can be collected via Fulcrum if they don't already exist.This workshop will be taught twice in June. Both workshops will be part of the Community Health Maps project and are partly funded by the National Library of Medicine (funding for the workshop is provided under a sub-award from the National Library of Medicine to ICF International). The first iteration will be taught in conjunction with the 
At three hours the workshop was slightly shorter than normal. This allowed us to focus on field data collection with 
Due to great outreach by the University of Michigan team of - Tyler Nix, Marisa Conte, Alexa Rivera, Justin Schell, Sara McDonnell, Troy Rosencrants, Kui-Bin Im and Claudia Walters - the workshops had great attendance and ran like clockwork.The first was held at the University of Michigan - Ann Arbor at the Hatcher Graduate 
The second was held the following day at the UM Flint. We started in the University Center Happenings Room and moved to Thompson Library for the afternoon QGIS session. Forty five people came out for
The third was held at the UM Detroit Center on April 4th. Thirty people registered for this workshop. This was probably the most diverse group including some UM faculty, plus Wayne State faculty, county public health staff (including some as far away as Saginaw County) and non-profit public health workers.
The fourth was held at UM Dearborn on April 5th. This was the smallest of the fo
One of the most helpful components was a 
The presentation covered a basic introduction to the tools and workflow in CHM. The students were asked to use 
On their return, the students explored maps of their data points on Fulcrum. Many noted that the process of collecting data points was easy and fun. UMD Professor James Butler mentioned that although drinking a good amount of water is emphasized at the School of Public Health, he had not previously noticed that there is no water fountain near the faculty lounge. His comment underscored that issues are often not observed until actively examined, as during the mapping process.
The class ended with Professor Butler concluding the class by reiterating how CHM can serve as a useful tool for visualizing many of the different health issues discussed in class.The students were alerted to the free new online 
The first afternoon was focused on the impacts of climate change, preparedness and building resilience. There were great presentations on climate change (Capt. Barry Choy - NOAA), an overview of the tools and programs available from the CDC (Paul Schramm), and issues with vector-borne diseases and mosquitoes (Janet McAllister). The ASTHO grantees then gave some some sobering presentations on current issues people are dealing with in the Mariana Islands, Micronesia and the U.S. Virgin Islands.
The second day focused more on tools and resources. There were more detailed talks given by the CDC on Technical Assistance for Vector Control and Tools and Resources for Climate and Water Safety. That afternoon we taught a 3.5 hour Community Health Maps Train-the-Trainers workshop to a group of health officials from each territory. We went through the entire CHM workflow: A) how to design a data collection form, B) how to collect data, C) how to make a map in Carto and D) how to bring the data into QGIS.
Most of the trainees had little to no GIS training yet instantly knew how mapping could apply to their work and lives. They want to map everything related to hurricane relief, salt water resistant taro farms, infrastructure related to mosquito outbreaks etc. A benefit of having the community do this is that they can be in charge of their own data and it helps build community relationships.Over the three days I heard a lot of side discussions about the usefulness of the free/low cost/open source CHM approach. The cost of proprietary solutions is often a significant barrier to entry into the world of community data collection and mapping. We were gratified to hear some very positive feedback on the workshops and CHM overall during the closing session. There seems to be a lot of potential in CHM helping both U.S. Territories and ASTHO deal with the immediate and long-term health issues related to climate.
The first presentation was held during a seventy-five minute “Principles of CommunityHealth” class of twenty-five undergraduates. A second was provided to a close-knitclass of ten graduate students studying community health and health literacy.After an introduction to Community Health Maps and to the history and ideology ofGIS/mapping in health research, students used 
The following is a question and answer interview with the moderator of the with Community Health Maps (CHM) blog, 
a listserv. At first it was very limited, being little more than a data viewer. But I was really curious to see how it might evolve, so I started following it. It really started becoming a useful alternative in 2010. I gradually migrated to it with my business. I also started teaching GIS classes with it. I used to keep a list of things you could do with ArcGIS that you couldn't in QGIS. Now it's come so far that I have a list of things you can do in QGIS that you can't in ArcGIS!How has CHM evolved?Kurt: Once we realized we had something that would be useful to people, we began looking for partner organizations. These are organizations who work with data and can benefit from mapping, but lack the resources to get started. We conduct workshops and webinars to get people started down the mapping path.Along the way I thought a blog would be a really helpful tool to keep people up to date with new technology. These tools are constantly improving and I thought this would be a way to share these enhancements with everyone. Later we realized we needed additional resources for people to continue to build their skills after the initial workshops. I developed a series of 
Our primary goal for CHM has always been to provide tools that are helpful to users. After years of trying to build something from scratch, we are now finally gaining some traction with CHM. It feels like a snowball, rolling downhill and gaining speed. I believe it is both because the tools are powerful and intuitive, plus we are getting better at identifying potential users.Would you recount one experience with CHM that felt especially influential for CHM’s progress so far? Kurt: Yes the first thing that comes to mind is the work with the 
Several projects were inspired these MUSC workshops. Of particular note is Dr. Bryan Heckman’s 
The most gratifying aspect of these workshops was seeing people shed their technological insecurities. It’s common for people to show up and admit they’re scared of the technology. To then see in a few short hours, they are getting it all to work, and actually getting excited about the possibilities, is a beautiful thing. What are your plans for the future of CHM? Kurt: The work that people are doing right now with CHM barely scratches the surface in terms of the potential. I would like to get more community members involved. I envision a scenario where there is an organization can really engage with citizens to map the community. The data could be managed by a central data manager in the organization. It would be such a great way to involve the community in a project directly related to their healthcare.I’d also like to see someone get past the initial data gathering and map making phase. QGIS has a lot of spatial analysis capabilities. I’d like to see someone push beyond the CHM labs and do some interesting analyses in QGIS or use some of the cool data visualization techniques in Carto.What advice you would give to new CHM users?Kurt: Don’t be afraid to dive in and use the tools. Be adventurous and creative with your projects. Don’t be afraid to mess up. That’s how you learn. There is no limit to the kinds of things you can accomplish with mapping and spatial analysis tools. If you can imagine it, it can be done.
