“…This study confirms in an area with relatively low entomological indices previously observed short-lived effect of the use of insecticides on A. aegypti infestation (Gubler & Clark 1996;Castle et al 1999;Spiegel et al 2005). The main finding, however, is that (concomitant) top-down substitution of defective water storage containers -however, efficacious from a technocratic a priori point of view-does not ensure a sustained impact on entomological indices without an accompanying strategy for achieving behavioural change.…”

“…Reports from various countries indicate that vertical A. aegypti control activities are not sustainable (Nathan & Knudsen 1991;Winch et al 1992;Rosenbaum et al 1995) and that isolated vector control initiatives do not promote behavioural change (Castle et al 1999;. Kay and Vu (2005) suggested that sustained chemical control efforts coupled with active community participation in source reduction and environmental management are probably the most effective venue to prevent dengue epidemics.…”

Summaryobjective To identify key elements that should provide an added value and assure sustainable effects of the deployment of technical tools for Aedes aegypti control. We assessed community perceptions and household risk behaviour at baseline and after 9 months, and measured the trial's impact through entomological indices.results Perceived self efficacy to solve A. aegypti infestation and prevent dengue was not modified. We found no changes in behaviour. In the study area the container indices decreased significantly from 0.7% before to 0.1% 1 month after the intervention. Six months later, they had increased to 2.7% and uncovered new water tanks constituted 75.9% of all breeding sites. Over the 9 months after the trial the average monthly house indices were similar in the study and control areas. A technical approach and lack of community involvement in the trial's implementation were the main causes of these short-lived results.conclusions Top-down deployment of technical tools without active involvement of the community has a temporary effect and does not lead to the behavioural changes necessary for sustainable A. aegypti control.

Abstract. The home, or domicile, is the principal environment for transmission of dengue virus (DENV) between humans and mosquito vectors. Community-wide distribution of insecticide-treated curtains (ITCs), mimicking vector control program-driven interventions, has shown promise to reduce DENV infections. We conducted a Casa Segura consumer product intervention study in Mérida, Mexico to determine the potential to reduce intradomicillary DENV transmission through ITC use in individual homes. Dengue virus infections in mosquitoes and in humans were reduced in homes with ITCs in one of two study subareas. Overall, ITCs reduced intradomicillary DENV transmission; ITC homes were significantly less likely to experience multiple DENV infections in humans than NTC homes. Dengue virus-infected Aedes aegypti females were reduced within the ITC homes where curtain use was highest. Some homes yielded up to nine infected Ae. aegypti females. This study provides insights regarding best practices for Casa Segura interventions to protect homes from intradomicillary DENV transmission.

“…Dengue hemorrhagic fever was recorded for the first time in Trinidad in 1992-1993, 10 while in 1995, Jamaica recorded 108 cases of DHF and 3 cases of DSS, with a total of 4 deaths. 11 Large outbreaks of dengue occurred in Barbados in 1995 and 1997, and dengue cases detected in the hospital-based diagnostic protocol outnumbered leptospirosis cases. These outbreaks were associated predominantly with circulation of serotype 1 (1995) and serotype 2 (1997), placing the population at high risk of DHF.…”

Abstract. The annual incidence of leptospirosis in Barbados is approximately 13 severe cases/100,000. The peak incidence occurs in October to December of each year, coinciding with the months of heaviest rainfall. During the second half of 1995, an epidemic of dengue type 1 infection produced almost 1,000 laboratory-confirmed cases. During the same period, leptospirosis mortality was twice the average, suggesting that some cases of leptospirosis were being misdiagnosed and treated inappropriately. Sera from patients investigated for dengue or leptospirosis were analyzed retrospectively to determine the extent of misdiagnosis. During 1995 and 1996, 31 of 139 and 29 of 93 patients, respectively, were confirmed as having leptospirosis. Sera from the remaining leptospirosis-negative patients were tested for IgM antibodies to dengue virus. During 1995 and 1996, 48 of 108 patients and 21 of 64 patients, respectively, were found to have dengue. In 1997, sera from all patients investigated for leptospirosis were also tested prospectively for IgM antibodies to dengue: 38 of 92 leptospirosis-negative patients (41%) were dengue IgM-positive, while 2 of 25 leptospirosis cases also had serologic evidence suggesting acute dengue infection. A second large outbreak of dengue caused by serotype 2 occurred in 1997. During the 1995 and 1997 dengue epidemics in Barbados, dengue cases outnumbered leptospirosis cases investigated in the leptospirosis diagnostic protocol. During 1997, patients investigated but negative for dengue were also tested for anti-leptospiral IgM: 7.3% (19 of 262) were IgMpositive. Substantial misdiagnosis of both dengue and leptospirosis can occur and greater public awareness and clinical suspicion of the similar presentations of these two diseases are necessary.Dengue fever is included within the group of emerging or re-emerging infectious diseases of public health significance.
