These factors contribute to the state being the national ground zero for exotic mosquito-borne diseases, as evidenced by local transmission of viruses spread by Aedes aegypti, including outbreaks of dengue in 2022 and Zika in 2016. Because of limited treatment options, integrated vector management is a key part of mitigating these arboviruses. Practical knowledge of when and where mosquito populations of interest exist is critical for surveillance and control efforts, and habitat predictions at various geographic scales typically rely on ecological niche modeling. However, most of these models, usually created in partnership with academic institutions, demand resources that otherwise may be too time-demanding or difficult for mosquito control programs to replicate and use effectively. Such resources may include intensive computational requirements, high spatiotemporal resolutions of data not regularly available, and/or expert knowledge of statistical analysis. Therefore, our study aims to partner with mosquito control agencies in generating operationally useful mosquito abundance models. Given the increasing threat of mosquito-borne disease transmission in Florida, our analytic approach targets recent Ae. aegypti abundance in the Tampa Bay area. We investigate explanatory variables that: 1) are publicly available, 2) require little to no preprocessing for use, and 3) are known factors associated with Ae. aegypti ecology. Out of our 4 final models, none required more than 5 out of the 36 predictors assessed (13.9%). Similar to previous literature, the strongest predictors were consistently 3- and 4-wk temperature and precipitation lags, followed closely by 1 of 2 environmental predictors: land use/land cover or normalized difference vegetation index. Surprisingly, 3 of our 4 final models included one or more socioeconomic or demographic predictors. In general, larger sample sizes of trap collections and/or citizen science observations should result in greater confidence in model predictions and validation. However, given disparities in trap collections across jurisdictions, individual county models rather than a multicounty conglomerate model would likely yield stronger model fits. Ultimately, we hope that the results of our assessment will enable more accurate and precise mosquito surveillance and control of Ae. aegypti in Florida and beyond.}, Doi = {10.2987/22-7109}, Key = {fds371620} } @article{fds370207, Author = {Uelmen, JA and Kopsco, H and Mori, J and Brown, WM and Smith, RL}, Title = {Modeling community COVID-19 transmission risk associated with U.S. universities.}, Journal = {Scientific reports}, Volume = {13}, Number = {1}, Pages = {1428}, Year = {2023}, Month = {January}, url = {http://dx.doi.org/10.1038/s41598-023-28212-z}, Abstract = {The ongoing COVID-19 pandemic is among the worst in recent history, resulting in excess of 520,000,000 cases and 6,200,000 deaths worldwide. The United States (U.S.) has recently surpassed 1,000,000 deaths. Individuals who are elderly and/or immunocompromised are the most susceptible to serious sequelae. Rising sentiment often implicates younger, less-vulnerable populations as primary introducers of COVID-19 to communities, particularly around colleges and universities. Adjusting for more than 32 key socio-demographic, economic, and epidemiologic variables, we (1) implemented regressions to determine the overall community-level, age-adjusted COVID-19 case and mortality rate within each American county, and (2) performed a subgroup analysis among a sample of U.S. colleges and universities to identify any significant preliminary mitigation measures implemented during the fall 2020 semester. From January 1, 2020 through March 31, 2021, a total of 22,385,335 cases and 374,130 deaths were reported to the CDC. Overall, counties with increasing numbers of university enrollment showed significantly lower case rates and marginal decreases in mortality rates. County-level population demographics, and not university level mitigation measures, were the most significant predictor of adjusted COVID-19 case rates. Contrary to common sentiment, our findings demonstrate that counties with high university enrollments may be more adherent to public safety measures and vaccinations, likely contributing to safer communities.}, Doi = {10.1038/s41598-023-28212-z}, Key = {fds370207} } @article{fds370208, Author = {Holcomb, KM and Mathis, S and Staples, JE and Fischer, M and Barker, CM and Beard, CB and Nett, RJ and Keyel, AC and Marcantonio, M and Childs, ML and Gorris, ME and Rochlin, I and Hamins-Puértolas, M and Ray, EL and Uelmen, JA and DeFelice, N and Freedman, AS and Hollingsworth, BD and Das, P and Osthus, D and Humphreys, JM and Nova, N and Mordecai, EA and Cohnstaedt, LW and Kirk, D and Kramer, LD and Harris, MJ and Kain, MP and Reed, EMX and Johansson, MA}, Title = {Evaluation of an open forecasting challenge to assess skill of West Nile virus neuroinvasive disease prediction.}, Journal = {Parasites & vectors}, Volume = {16}, Number = {1}, Pages = {11}, Year = {2023}, Month = {January}, url = {http://dx.doi.org/10.1186/s13071-022-05630-y}, Abstract = {<h4>Background</h4>West Nile virus (WNV) is the leading cause of mosquito-borne illness in the continental USA. WNV occurrence has high spatiotemporal variation, and current approaches to targeted control of the virus are limited, making forecasting a public health priority. However, little research has been done to compare strengths and weaknesses of WNV disease forecasting approaches on the national scale. We used forecasts submitted to the 2020 WNV Forecasting Challenge, an open challenge organized by the Centers for Disease Control and Prevention, to assess the status of WNV neuroinvasive disease (WNND) prediction and identify avenues for improvement.<h4>Methods</h4>We performed a multi-model comparative assessment of probabilistic forecasts submitted by 15 teams for annual WNND cases in US counties for 2020 and assessed forecast accuracy, calibration, and discriminatory power. In the evaluation, we included forecasts produced by comparison models of varying complexity as benchmarks of forecast performance. We also used regression analysis to identify modeling approaches and contextual factors that were associated with forecast skill.<h4>Results</h4>Simple models based on historical WNND cases generally scored better than more complex models and combined higher discriminatory power with better calibration of uncertainty. Forecast skill improved across updated forecast submissions submitted during the 2020 season. Among models using additional data, inclusion of climate or human demographic data was associated with higher skill, while inclusion of mosquito or land use data was associated with lower skill. We also identified population size, extreme minimum winter temperature, and interannual variation in WNND cases as county-level characteristics associated with variation in forecast skill.<h4>Conclusions</h4>Historical WNND cases were strong predictors of future cases with minimal increase in skill achieved by models that included other factors. Although opportunities might exist to specifically improve predictions for areas with large populations and low or high winter temperatures, areas with high case-count variability are intrinsically more difficult to predict. Also, the prediction of outbreaks, which are outliers relative to typical case numbers, remains difficult. Further improvements to prediction could be obtained with improved calibration of forecast uncertainty and access to real-time data streams (e.g. current weather and preliminary human cases).}, Doi = {10.1186/s13071-022-05630-y}, Key = {fds370208} } @article{fds370209, Author = {Uelmen, JA and Lamcyzk, B and Irwin, P and Bartlett, D and Stone, C and Mackay, A and Arsenault-Benoit, A and Ryan, SJ and Mutebi, J-P and Hamer, GL and Fritz, M and Smith, RL}, Title = {Human biting mosquitoes and implications for West Nile virus transmission.}, Journal = {Parasites & vectors}, Volume = {16}, Number = {1}, Pages = {2}, Year = {2023}, Month = {January}, url = {http://dx.doi.org/10.1186/s13071-022-05603-1}, Abstract = {<h4>Background</h4>West Nile virus (WNV), primarily vectored by mosquitoes of the genus Culex, is the most important mosquito-borne pathogen in North America, having infected thousands of humans and countless wildlife since its arrival in the USA in 1999. In locations with dedicated mosquito control programs, surveillance methods often rely on frequent testing of mosquitoes collected in a network of gravid traps (GTs) and CO<sub>2</sub>-baited light traps (LTs). Traps specifically targeting oviposition-seeking (e.g. GTs) and host-seeking (e.g. LTs) mosquitoes are vulnerable to trap bias, and captured specimens are often damaged, making morphological identification difficult.<h4>Methods</h4>This study leverages an alternative mosquito collection method, the human landing catch (HLC), as a means to compare sampling of potential WNV vectors to traditional trapping methods. Human collectors exposed one limb for 15 min at crepuscular periods (5:00-8:30 am and 6:00-9:30 pm daily, the time when Culex species are most actively host-seeking) at each of 55 study sites in suburban Chicago, Illinois, for two summers (2018 and 2019).<h4>Results</h4>A total of 223 human-seeking mosquitoes were caught by HLC, of which 46 (20.6%) were mosquitoes of genus Culex. Of these 46 collected Culex specimens, 34 (73.9%) were Cx. salinarius, a potential WNV vector species not thought to be highly abundant in upper Midwest USA. Per trapping effort, GTs and LTs collected > 7.5-fold the number of individual Culex specimens than HLC efforts.<h4>Conclusions</h4>The less commonly used HLC method provides important insight into the complement of human-biting mosquitoes in a region with consistent WNV epidemics. This study underscores the value of the HLC collection method as a complementary tool for surveillance to aid in WNV vector species characterization. However, given the added risk to the collector, novel mitigation methods or alternative approaches must be explored to incorporate HLC collections safely and strategically into control programs.}, Doi = {10.1186/s13071-022-05603-1}, Key = {fds370209} } @article{fds373495, Author = {Leosari, Y and Uelmen, JA and Carney, RM}, Title = {Spatial evaluation of healthcare accessibility across archipelagic communities of Maluku Province, Indonesia.}, Journal = {PLOS global public health}, Volume = {3}, Number = {3}, Pages = {e0001600}, Year = {2023}, Month = {January}, url = {http://dx.doi.org/10.1371/journal.pgph.0001600}, Abstract = {The Maluku Province is an underdeveloped region in Indonesia with over 1,340 scattered islands. Due to the limited health facilities and transportation infrastructure, access to healthcare is very challenging. Here, we combined data from various sources to locate the population clusters, health facilities, roads, and ports/docks, and then utilize geographic information systems (GIS) to estimate distances from residents to health facilities. Health workforce distribution data was then integrated to elucidate overall healthcare equity among districts in the province. The average distances to puskesmas (primary health clinics) were 8.89 km (by land) and 18.43 km (by land and water) respectively, and the average distances to hospitals were 56.19 km (by land) and 73.09 km (by land and water), with large disparities within and among districts. Analysis of health workforce data shows that 65% of 207 puskesmas lack physicians, while 49% lack midwives. Ambon, Tual, and Southeast Maluku have the highest health equity, while East Ceram, Buru, and South Buru have the lowest. In general, this study demonstrates the utility of GIS and spatial analyses, which can help identify problem areas in healthcare accessibility and equity in archipelago settings, and provide recommendations to stakeholders such as public health officials and district administrators.}, Doi = {10.1371/journal.pgph.0001600}, Key = {fds373495} } @article{fds374605, Author = {Carney, RM and Long, A and Low, RD and Zohdy, S and Palmer, JRB and Elias, P and Bartumeus, F and Njoroge, L and Muniafu, M and Uelmen, JA and Rahola, N and Chellappan, S}, Title = {Citizen Science as an Approach for Responding to the Threat of Anopheles stephensi in Africa}, Journal = {Citizen Science: Theory and Practice}, Volume = {8}, Number = {1}, Year = {2023}, Month = {January}, url = {http://dx.doi.org/10.5334/cstp.616}, Abstract = {Even as novel technologies emerge and medicines advance, pathogen-transmitting mosquitoes pose a deadly and accelerating public health threat. Detecting and mitigating the spread of Anopheles stephensi in Africa is now critical to the fight against malaria, as this invasive mosquito poses urgent and unprecedented risks to the continent. Unlike typical African vectors of malaria, An. stephensi breeds in both natural and artificial water reservoirs, and flourishes in urban environments. With An. stephensi beginning to take hold in heavily populated settings, citizen science surveillance supported by novel artificial intelligence (AI) technologies may offer impactful opportunities to guide public health decisions and community-based interventions. Coalitions like the Global Mosquito Alert Consortium (GMAC) and our freely available digital products can be incorporated into enhanced surveillance of An. stephensi and other vector-borne public health threats. By connecting local citizen science networks with global databases that are findable, accessible, interoperable, and reusable (FAIR), we are leveraging a powerful suite of tools and infrastructure for the early detection of, and rapid response to, (re)emerging vectors and diseases.}, Doi = {10.5334/cstp.616}, Key = {fds374605} } @article{fds373661, Author = {Wan, GW and Allen, J and Ge, W and Rawlani, S and Uelmen, J and Mainzer, LS and Smith, RL}, Title = {Two-Step Light Gradient Boosted Model to identify human West Nile Virus infection risk factor in Chicago}, Volume = {19}, Number = {1}, Pages = {e0296283}, Booktitle = {medRxiv}, Year = {2023}, url = {http://dx.doi.org/10.1101/2023.05.09.23289737}, Abstract = {West Nile virus (WNV), a flavivirus transmitted by mosquito bites, causes primarily mild symptoms but can also be fatal. Therefore, predicting and controlling the spread of West Nile virus is essential for public health in endemic areas. We hypothesized that socioeconomic factors may influence human risk from WNV. We analyzed a list of weather, land use, mosquito surveillance, and socioeconomic variables for predicting WNV cases in 1-km hexagonal grids across the Chicago metropolitan area. We used a two-stage lightGBM approach to perform the analysis and found that hexagons with incomes above and below the median are influenced by the same top characteristics. We found that weather factors and mosquito infection rates were the strongest common factors. Land use and socioeconomic variables had relatively small contributions in predicting WNV cases. The Light GBM handles unbalanced data sets well and provides meaningful predictions of the risk of epidemic disease outbreaks.}, Doi = {10.1101/2023.05.09.23289737}, Key = {fds373661} } | ||
