“…High variation in sensitivity of manual inspection has been recorded between previous studies. In contrast, the sensitivity of collection by householders remained high between studies (Gü rtler et al 1999, Esteban et al 2006, Parra et al 2006, Feliciangeli et al 2007, Abad-Franch et al 2011, Yoshioka 2013, indicating that inhabitants were motivated to improve their own situation, and hence a community-based program could be highly successful. In Venezuela, collection by householders identiÞed 99.2% of all the houses found to be positive, whereas the method with the second highest efÞcacy, manual inspection, identiÞed only 5.3% of the infested houses (Feliciangeli et al 2007).…”

In Guatemala, Þve-to sixfold more triatomines were collected by householders in 1 wk than traditional methods collect in 1 yr (Yoshioka 2013). As well as being highly sensitive, the former method promotes community involvement and has been found to be highly acceptable and cost effective.…”

“…The collection of bugs by householders has been found to be a sensitive and speciÞc method of triatomine surveillance, and provide one of the earliest indicators of an infestation (Gü rtler et al 1999, Esteban et al 2006, Parra et al 2006, Feliciangeli et al 2007, Abad-Franch et al 2011, Yoshioka 2013. Collection pots or bags can be distributed, and householders are asked to capture any triatomine bugs they Þnd over a set time period.…”

In Guatemala, the most widespread vector of Trypanosoma cruzi (Kinetoplastida: Trypanosomatidae), the causative agent of Chagas disease, is Triatoma dimidiata (Latreille) (Hemiptera: Reduviidae: Triatominae). T. dimidiata is native to Guatemala and is present in both domestic and sylvatic habitats. Consequently, control of T. dimidiata is difficult because after successful elimination from homes, individual insects can recolonize homes from the surrounding environment. Therefore, intensive long-term surveillance of this species is essential to ensure adequate control is achieved. Manual inspection for signs of infestation, the current method used to monitor Triatominae throughout Central and South America, is labor and time-consuming, so cost-effective alternatives are needed. The current study compared the effectiveness of the current method of surveillance of T. dimidiata with community-based techniques of G6mez-Nuñez sensor boxes, collection and observation of bugs by householders, and presence of triatomine-like feces on walls. Although manual inspection was the most sensitive method when used alone, collection by householders also was sensitive and specific and involved less effort. Sensor boxes were not sensitive indicators of T. dimidiata infestation when used alone. Two recorded variables, visual inspection for feces and the sighting of bugs by householders, were sensitive and specific indicators of infestation, and in combination with collection by householders and sensor boxes these methods were significantly more likely to detect infestations than manual inspection alone. A surveillance program that combines multiple community-based techniques should have low cost and involve minimal effort from the government and at the same time promote sustainable community involvement in disease prevention.

“…The analysis of citizen-collected data presents unique challenges due to observer error and sampling bias [ 3 ]. For example, public submission programs result non-target bug species [ 32 , 33 ]; however this potential source of observer error is controlled for in our program by laboratory identification of all kissing bugs. The geographic breadth of submissions reflects the area over which citizens are aware of the program and able to contribute to it.…”

BackgroundChagas disease is a zoonotic parasitic disease well-documented throughout the Americas and transmitted primarily by triatomine ‘kissing bug’ vectors. In acknowledgment of the successful history of vector control programs based on community participation across Latin America, we used a citizen science approach to gain novel insight into the geographic distribution, seasonal activity, and Trypanosoma cruzi infection prevalence of kissing bugs in Texas while empowering the public with information about Chagas disease.Methodology/Principal FindingsWe accepted submissions of kissing bugs encountered by the public in Texas and other states from 2013–2014 while providing educational literature about Chagas disease. In the laboratory, kissing bugs were identified to species, dissected, and tested for T. cruzi infection. A total of 1,980 triatomines were submitted to the program comprised of at least seven species, of which T. gerstaeckeri and T. sanguisuga were the most abundant (85.7% of submissions). Triatomines were most commonly collected from dog kennels and outdoor patios; Overall, 10.5% of triatomines were collected from inside the home. Triatomines were submitted from across Texas, including many counties which were not previously known to harbor kissing bugs. Kissing bugs were captured primarily throughout April-October, and peak activity occurred in June-July. Emails to our dedicated account regarding kissing bugs were more frequent in the summer months (June-August) than the rest of the year. We detected T. cruzi in 63.3% of tested bugs.Conclusions/SignificanceCitizen science is an efficient approach for generating data on the distribution, phenology, and infection prevalence of kissing bugs—vectors of the Chagas disease parasite—while educating the public and medical community.

“…Community-based surveillance has been shown to be effective and cost-effective, but can be challenging to sustain [ 11 – 14 ]. Household infestation with vectors can be detected readily by inhabitants, and in turn, health services are expected to respond to every vector report by visiting houses to spray insecticide and provide educational advice [ 9 , 11 ].…”

BackgroundCentral American countries face a major challenge in the control of Triatoma dimidiata, a widespread vector of Chagas disease that cannot be eliminated. The key to maintaining the risk of transmission of Trypanosoma cruzi at lowest levels is to sustain surveillance throughout endemic areas. Guatemala, El Salvador, and Honduras integrated community-based vector surveillance into local health systems. Community participation was effective in detection of the vector, but some health services had difficulty sustaining their response to reports of vectors from the population. To date, no research has investigated how best to maintain and reinforce health service responsiveness, especially in resource-limited settings.Methodology/Principal FindingsWe reviewed surveillance and response records of 12 health centers in Guatemala, El Salvador, and Honduras from 2008 to 2012 and analyzed the data in relation to the volume of reports of vector infestation, local geography, demography, human resources, managerial approach, and results of interviews with health workers. Health service responsiveness was defined as the percentage of households that reported vector infestation for which the local health service provided indoor residual spraying of insecticide or educational advice. Eight potential determinants of responsiveness were evaluated by linear and mixed-effects multi-linear regression. Health service responsiveness (overall 77.4%) was significantly associated with quarterly monitoring by departmental health offices. Other potential determinants of responsiveness were not found to be significant, partly because of short- and long-term strategies, such as temporary adjustments in manpower and redistribution of tasks among local participants in the effort.Conclusions/SignificanceConsistent monitoring within the local health system contributes to sustainability of health service responsiveness in community-based vector surveillance of Chagas disease. Even with limited resources, countries can improve health service responsiveness with thoughtful strategies and management practices in the local health systems.
