The Second Vector Borne Disease Surveillance Workshop
On June 18 & 19, 2019, eight state based health officials took the second Vector Borne Disease Surveillance workshop in Providence, Rhode Island. This was the second of two 2-day workshops aimed specifically at tackling the spread of diseases like Dengue fever, West Nile and Zika viruses. As with the first one, this was 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 health departments in: Colorado, Georgia, Kansas, Louisiana, Mississippi, New Mexico, Virginia and Guam.Again this workshop 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 Emerging and Zoonotic Infectious Diseases. 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 State Environmental Health Directors (SEHD) Peer Network Annual Meeting.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.For the remainder of the first day, the group took the data they collected earlier and imported into QGIS. 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. The participants:A) generated trend graphs of mosquito populations through time via the QGIS Data Plotly plugin,
B) generated heatmaps of mosquito populations,
C) calculated the minimum infection rate per year for West Nile and St. Louis Encephalitis viruses,
D) identified potential mosquito sources to be inspected (storm drains) using a combination of a buffer operation (done against mosquito complaints with the distance the species is known to be able to travel) and select by location against storm drains,
E) identified parcels at risk due to their proximity to a fictional outbreak of Dengue Fever,
and F) learned to animate temporal data using the QGIS Time Manager plugin. Here the mosquito population (heatmap) is being animated weekly for the year 2018 with mosquito management zones be displayed.
All participants received official QGIS certificates for their participation.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)
The presentation took place within a 95-minute class period with 53 students. The presenters introduced the CHM blog and briefly touched on using Geographic Information Systems (GIS)/spatial analysis to address a public health concerns, as English physician John Snow did in 1854 by mapping the source of a 
The students then completed a hands-on data collection exercise. They were introduced to 
The QGIS conference was small and intimate and a lot of new information was shared by the developers about the future of QGIS.
There was so much presented that this will be a separate future blog post. While there Kurt conducted a full day workshop on Data Visualization and Cartography in QGIS.
He shared many of the new sophisticated and powerful data styling tools now found in QGIS including: 2.5D, 3D, Live Layer Effects, Inverted Polygon Shapeburst Fills, Blending Modes, and some plugins such as Time Manager. Perhaps this could be a workshop shared with CHM partners at a future date? Some examples are shown below:
In Boston Kurt presented the Community Health Maps project. The talk was well attended and there was a lot of interest. 
The relevance of the CHM initiative to NLM’s mission has to do with improving the ability of community-oriented organizations (and researchers and other public health professionals) to collect, organize and visualize data and other health information to better-understand health conditions and support decision-making for resource allocation. While access to quality health information is frequently a focus of attention, the ability to visualize data and information -- to better understand and portray their significance to the community -- has received less attention. This is in part because the availability of affordable GIS platforms and data collection and visualization applications is relatively recent. Historically, the cost to procure platforms and applications, to train users and to sustain operations has been prohibitive for communities and community-based organizations whose health budgets are already strained.The purpose of the workshop, therefore was to share the CHM workflow with community-based and minority health organizations so that they would be in a better position to serve their populations by knowing how to collect and maintain their own data, rather than -- or at least in addition to -- having to rely solely on national/state agencies or majority-institution partners to provide data to them.Participating were seventy-six community-oriented health professionals who were drawn from throughout the country. The workshop was made possible with funding by the Robert Wood Johnson Foundation. During the workshop several Community Health Mapping pilot projects were highlighted, including:

After the two PG County workshops, CHM traveled across the Chesapeake Bay bridge to Salisbury University on the eastern shore.
The following morning we held a workshop geared towards social work students at Salisbury University. Attendees went through the CHM workflow and were introduced to

This event was organized by the Northwest Portland Area Indian Health Board and supported by the Robert Wood Johnson Foundation. We weren't certain who or how many would attend, and I expect attendees weren't entirely sure what Community Health Mapping was all about either. However, it turned out to be a very engaged group representing tribes from many regions of the country. Within a few hours everyone was able to:
After a brief break we headed to Seattle, Washington, again there were two separate storms including, the remnants of Typhoon Songda, bearing down on the region threatening to disrupt power and services! Again fortunately the storms didn't make a direct hit on the area and the workshop proceeded on schedule.We went to train students in the capstone course of the Community Oriented Public Health Practice Program at the University of Washington. This is our second year supporting this program. The first year was a huge success with two students attending the
