heartworm prevalence by zip code

2022 Sep 7;13(9):814. doi: 10.3390/insects13090814. The .gov means its official. While mosquito diversity had a positive relationship with host heartworm prevalence in the model, household income had a negative relationship with host heartworm prevalence, supporting our hypothesis that higher income areas would have less dog heartworm disease than lower income areas. J Am Vet Med Assoc. Contrary to our initial hypothesis, when comparing the land-use types of suburban neighborhoods, undeveloped woodlots and undeveloped fields, we found that field areas had significantly higher prevalence and likelihood of heartworm-positive mosquitoes than did suburban areas.

However, since mosquitoes are responsible for transferring the parasite from dog to dog, some areas do pose a higher risk than others. https://www.heartwormsociety.org/veterinary-resources/incidence-maps. This approach sought to assess whether the heartworm status of mosquitoes was a reliable predictor of infection status within the host. Int J Environ Res Public Health. PubMed The American Heartworm Society (AHS) estimates that only 55% of dogs in the U.S. are currently on a heartworm preventive. We also sampled at 6 additional smaller parcels of land composed of undeveloped woodlots and 5 additional smaller parcels of land composed of undeveloped fields. At the wooded and field sites, traps were placed at least 100m away from any habitat edge, again consistent with previous findings of mosquito habitat fidelity [28]. We acquired median household income by zip code from the 20132017 American Community Survey using U.S. Census Bureaus American FactFinder tool [37] to investigate whether D. immitis prevalence within dogs and socioeconomic status is correlated. The first test compared heartworm prevalence between suburban, natural woodlot and natural field sites with all neighborhood ages collapsed into a single suburban category (three total treatment levels). a Heartworm prevalence within dogs ranged from 3.77% to 15.64% within zip codes where mosquitoes were sampled. | Post Office Box 1352, Holly Springs, NC 27540 USA. The focus of studies on primary vectors rather than communities of vectors has led to a general gap in knowledge as to how vector diversity contributes to disease transmission in multi-vectored pathosystems, even though the limited empirical and modeling investigations that have occurred suggest vector diversity can increase transmission [5, 6]. The Heartworm Hotline column is presented in partnership between Todays Veterinary Practice and the American Heartworm Society (heartwormsociety.org). albopictus as the areas primary vector [21]. The parasite develops through multiple larval stages within the mosquito, culminating in the host-infective third larval stage (L3), which enters the bite wound of a susceptible host during the mosquitos next blood-feeding. In most cases, the utilization of AHS resources was higher than that reported in the 2013 and 2016 surveys (. We calculated the bias corrected maximum likelihood estimate (MLE) for point estimation of the infection rate of each heartworm-positive mosquito species using PooledInfRate add-in software for Excel [34].

No apparent seasonal trends in D. immitis-positive status were noted within the mosquito trapping season (see Additional file 2: Figure S1). Urban and suburban development is predicted to increase by greater than 100% over the next 50years in the southeastern USA [48], in line with global trends of increasing urbanization. Lights were removed from the CDC light traps to reduce by-catch. The zip code of the surrendered or stray dog was noted at shelter intake, allowing analysis of trends at the scale of zip code level or larger. Mosquitoes are a diverse family of flies that can be pests and vectors of medical and veterinary significance, transmitting a wide array of viruses, protozoans and parasitic nematodes to both humans and animals.

We compared within-mosquito heartworm infection across land-use types by KruskalWallis and likelihood ratio tests. Google Scholar. This agrees with findings from a recent study that demonstrated a negative correlation between human population size and within-host heartworm prevalence [40]. Despite high rates of urbanization and ample examples of vector-borne diseases transmitted by multiple species, the effects of urbanization-driven mosquito diversity losses on disease transmission has not been well explored. All 50 states have had confirmed cases of heartworm since the disease's discovery back in 1856. Disease ecology; Diversity; Heartworm; Landscape; Mosquito; Urbanization; Vector. 1999;36:4418. Again, neighborhood age was not a significant factor, as the likelihood ratio test was not significant when incorporating neighborhood age categories into the analysis. Among veterinarians who saw cases drop over the past 3 years, the top 2 reasons they gave were (1), Veterinarians are seeking educational resources on heartworm disease. C'EST POUR AUJOURD'HUI ET POUR DEMAIN. While heartworm incidence dropped slightly in some parts of the country in 2019, more veterinarians overall noted an upward trend in heartworm incidence over the previous 3 years than a downward trend. Dr. Carithers also currently serves as vice president of the AHS and president of the American Association of Veterinary Parasitologists. Although the response is likely different for diseases transmitted by one or few species, mosquito diversity losses leading to decreased transmission could be generalizable to other pathogens with multiple vectors. We investigated this question using the dog heartworm, a filarial parasite vectored by numerous mosquito species. 2011 Nov;26(4):178-85. doi: 10.1053/j.tcam.2011.09.005. MRSB collected mosquitoes and analyzed for the presence of dog heartworm DNA. Top Companion Anim Med. Dog heartworm disease is global in distribution and is likely the most common vector-borne disease in the USA, with prevalence in domestic dogs between 112.5% on average nationwide [17], but as high as 48.8% in certain highly endemic regions following natural disasters, like the Gulf Coast post-Hurricane Katrina [18]. Exposure to vector-borne pathogens in privately owned dogs living in different socioeconomic settings in Brazil. Ae. Using zip code level data acquired from dogs in a local shelter, we performed linear regressions of within-host heartworm prevalence by within-mosquito heartworm prevalence as well as by three mosquito diversity measures. 2003;40:78594. We then tested the null hypothesis that \(\sum p_{i} = p\) using a likelihood ratio test, utilizing the Holm method to correct for multiple comparisons when identifying which land-uses differed in their probabilities. He has been published in numerous magazines and newspapers over his career. Prevalence Maps: Is Heartworm In My Area? 5. 2009;54:46987. Provided by the Springer Nature SharedIt content-sharing initiative. PeerJ. We cannot assess spatial trends for D. immitis within mosquitoes due to low overall prevalence (Fig. Chitwood MC, Swingen MB, Lashley MA, Flowers JR, Palamar MB, Apperson CS, et al. Careers. 1).

Of the thousands of U.S. veterinary practices that report testing data to the AHS, a large proportion have reported data from their practice records year after year. ) Based on the results of a prior study of heartworm prevalence on an urban to rural gradient [21], we hypothesize that older neighborhoods with less diverse mosquito assemblages dominated by Ae. 2013;7:e2507. Preventives for Dogs Accessed 12 Jun 2019. We investigated this question using the dog heartworm, a filarial parasite vectored by numerous mosquito species. In 2001, the national estimate for heartworm-positive dogs was just under 900. See code. Epub 2014 Jun 5. However, decreases in mosquito diversity after human-driven land-use change could be detrimental when considering other disease systems of concern that are vectored by few mosquito species, such as dengue, chikungunya and Zika with Ae. https://doi.org/10.1186/s13071-019-3874-0, DOI: https://doi.org/10.1186/s13071-019-3874-0.

Based upon the increased abundance of suspected vectors, we originally predicted that older neighborhoods with less diverse mosquito assemblages would have greater dog heartworm prevalence, but this was not supported by our findings. Parasitology. As expected, people of higher socioeconomic status reported greater use of preventative medications, resulting in lower levels of vector-borne pathogens, including D. immitis [22]. Biggerstaff BJ. In the suburban neighborhoods, trap placement within the yard was based on the homeowners preference. The shift in mosquito assemblage to a lower richness community composed of a high proportion of known vectors likely increases disease transmission for most pathogens [9, 15]. Despite these limitations, shelter data presents a large, readily available dataset that generally cuts across various human demographics, including income and education levels [45], and is the best data currently available with which to test our predictions. Among models including all combinations of our tested variables (presence or absence of heartworm-positive mosquito pools, proportion heartworm-positive mosquito pools, rarefied richness, evenness, ShannonWiener diversity, mosquito abundance and median household income), selection revealed that the top model set (all models with AIC<2) included two models: (i) mosquito ShannonWiener diversity and median household income (AIC=23.95, residual df=15, AIC=0); and (ii) mosquito ShannonWiener diversity, mosquito rarefied richness and median household income (AIC=25.45, residual df=14, AIC=1.5). We performed real time quantitative polymerase chain reaction (qPCR) to assess for presence or absence of D. immitis DNA within the previously extracted and quantified mosquito pools. Braks MA, Honrio NA, Loureno-De-Oliveira R, Juliano SA, Lounibos LP. 2006;135:30314. Annu Rev Entomol. The qPCR procedure consisted of a denaturation step at 95C for 30s, followed by 40 cycles of denaturation at 95C for 5s, annealing at 60C for 15s and extension at 72C for 10seconds. Another gap in host data is accurate information on wild canid populations that could be serving as reservoirs of dog heartworm. MRSB analyzed and interpreted the data and prepared the original manuscript. Urban and suburban areas throughout much of the USA are dominated by the peridomestic Aedes albopictus, which is a competent vector of D. immitis [20]. Copyright 2023 American Heartworm Society. However, mosquito diversity metrics were positively correlated with host heartworm prevalence. We also found that the probability of an individual mosquito being positive for D. immitis differed between land-uses (LRT statistic =6.40, P=0.041). Almost 6000 veterinary practices and shelters participated in the AHS survey in early 2020. FOIA This could be due to increased preventative medication use in higher income areas [22], or to variation in other factors such as the amount of time a dog spends outside and therefore amount of potential mosquito exposure time.

If you are not sure of the full 9-digit ZIP Code, use the 5-digit ZIP Code to avoid loss of letter or package. All 50 states have had confirmed cases of heartworm since the diseases discovery back in 1856. Urbanization is one context in which vector assemblage and diversity vary, potentially with implications for heartworm disease transmission. All 50 states have had confirmed cases of heartworm since the disease's discovery back in 1856. Our previous work has shown that mosquito rarefied richness, evenness and ShannonWiener diversity is decreased in established suburban neighborhoods when compared with undeveloped natural areas [10]. Dr. Duke has special interest in orthopedic and reconstructive trauma surgery. Keywords: To disentangle the effects of mosquito diversity and mosquito abundance, we also calculated the average abundance within a zip code per site per trap-night and performed a linear regression comparing log average mosquito abundance to within-host heartworm prevalence. -. As a committee and board member for the AHS, he has conducted every AHS Heartworm Incidence Survey since 2001. For both suburban and urban areas generally, anthropogenic disturbance is also associated with increased abundance of vectors of human disease, including container-breeding Aedes that transmit dengue, Zika, or chikungunya viruses, and Culex mosquitoes, which transmit West Nile virus and human filarial pathogens [10, 11, 13, 14]. https://factfinder.census.gov/. doi: 10.1016/j.actatropica.2016.03.008. 1.5.0; 2018. https://github.com/arilamstein/choroplethrZip.

Using zip code level data acquired from dogs in a local shelter, we performed linear regressions of within-host heartworm prevalence by within-mosquito heartworm prevalence as well as by three mosquito diversity measures. 2017;54:118392. Within-host heartworm prevalence was well modeled by mosquito diversity and household income, further underscoring the effect of mosquito diversity while also illustrating the importance of socioeconomic status, possibly due to differences in administration of preventative medications. Address. Accessed 30 Jun 2018. To help veterinary professionals, shelter personnel, and pet owners understand heartworm trends in their areas, the American Heartworm Society (AHS) began tracking U.S. heartworm incidence in January 2002.

In fact, in a2016 AHS Incidence Survey, 10 percent of canines in Mississippi tested positive for the parasite. Apperson CS, Engber B, Levine JF. American Heartworm Society. Seasonal trends could also have been obscured by the overall low frequency of heartworm-positive mosquito pools. When comparing D. immitis prevalence within dogs to its prevalence within mosquitoes by zip code, no significant relationship was detected (F(1, 16)=0.511, P=0.485). However, when analyzing the 2015 data, percent heartworm-positive mosquito pools was positively correlated with percent parous mosquitoes across the trapping season (Fig. Mosquito (Diptera: Culicidae) Diversity and Community Structure in Doi Inthanon National Park, Northern Thailand. A significant positive correlation was noted between within-host heartworm prevalence and (. Geospat Health. In terms of percent D. immitis-positive mosquito pools, Ae. Any opinions, findings and conclusions or recommendations expressed in this material are those of the authors and do not necessarily reflect the views of the National Science Foundation. DGE-1746939. Each qPCR reaction consisted of 0.2l each of an established D. immitis-specific COI forward and reverse primer (DI COI primer pair) [32], 5l of SYBR green master mix, 2l of template DNA and 2.6l of water for a total reaction volume of 10l. Unfortunately, the lack of veterinary care translates to a lack of heartworm prevention, and these pets are among those most likely to be positive, infecting mosquitoes and other dogs in the neighborhood. One possible explanation for this discrepancy is that vector competence within a single mosquito species is susceptible to selection and can vary among geographically distinct populations [20, 41]. 5a, b). PLoS Negl Trop Dis. Since sample sizes varied among species, the number of positive pools and the total number of pools tested per species are provided above each bar, Relationship between mosquito parity and within-mosquito heartworm prevalence. Cats have up to a 1 in 3 chance of naturally fighting off a heartworm infection if they are exposed to infectious heartworm larvae. 7. Michael H. Reiskind. Model selection revealed within-host prevalence was best predicted by a positive relationship with mosquito ShannonWiener diversity and a negative relationship with household income.

According to the AHS survey, 82% reported that they follow the AHS guidelines on prevention, diagnosis, and treatment of heartworm disease, while more than half of practitioners utilize resources on the AHS website. Positive pools were confirmed via sequencing, with all pools aligning to a portion of the D. immitis mitochondrion [33]. [1,2,3,4]). To further investigate differences between land-use types while accounting for varying mosquito pool sizes during our molecular analysis, we used a likelihood ratio test to compare probability of within-mosquito D. immitis infection across land-use types. The 2019 AHS Heartworm Incidence map, as well as maps from 2001 to 2016, can be downloaded at heartwormsociety.org/veterinary-resources/incidence-maps. Yet throughout the trapping season, percent D. immitis-positive pools was positively correlated with mosquito parity data. Given that anthropogenic land-use change alters the diversity and composition of mosquito assemblages and is occurring rapidly worldwide, greater understanding of the role of vector diversity in multi-vectored diseases is critical and will have global impacts. The 2019 estimate dropped slightly to approximately 1.1 million infected dogs. We found that suburban areas generally had the lowest within-mosquito heartworm prevalence, and that mosquito diversity was positively correlated with heartworm prevalence within the canine host. Med Vet Entomol. In Mississippi, almost 10% of dogs tested for heartworms were heartworm positive in 2019; in Louisiana, just under 8% of dogs tested were positive. Parasit Vectors. Mosquitoes show habitat fidelity at a much finer scale of less than 100m [28], leading to a separation of geographical scale between mosquito-level factors and host-level factors that could be obscuring some trends. Privacy Parasites Vectors 13, 12 (2020). 2014;28(Suppl. Darsie RF. c While the relationship between within-host heartworm prevalence and mosquito rarefied richness was not significant (F(1, 16)=4.342, P=0.054, R2=0.213), a similar positive trend was found. If the local population is indeed refractory to D. immitis infection, that could drive the observed decreased heartworm prevalence in suburban areas, as over 40% of our trapped mosquitoes were Ae. Heartworms live approximately 5 to 7 years in the dog. albopictus. In addition to unmeasured host factors, this study is limited by the spatial scale of the within-dog heartworm prevalence data that we acquired.

Trapping occurred over two years, but both years were analyzed together to obtain a single average point estimate for each calendar week. However, since mosquitoes are responsible for transferring the parasite from dog to dog, some areas do pose a higher risk than others. We collected a total of 10,244 mosquitoes over the two years of sampling. These factors and more were cited in a recent survey of U.S. veterinarians as factors contributing to the rise and fall of heartworm incidence in their practice areas.
