“…longipalpis, the main vector of the VL agent of America, in Puerto Iguazú City, in the light of the significance of the area for public health. As the 2005 samplings did not register the presence of this sand fly in the urban area 21 , nor was any wild environment then found, the present study demonstrates the species "successful" colonization of some sectors of the city. Although the major proportion of sampled households showed moderate abundance, it is noteworthy that the minimum temperatures registered on those days were lower than the optimum estimated temperature threshold for the species in the region, i.e., 23 °C 16 .…”

“…longipalpis was detected in the urban area; some of the findings were associated with households where cases of canine VL had been reported 23 . In previous samplings conducted on the outskirts of the city, in rural areas and in the intersections of primary-secondary vegetation, the predominant species were Nyssomyia whitmani and Mg. migonei, both of which have been implicated in the spread of CL in several transmission scenarios 6,21 .…”

“…Nyssomyia whitmani has been implicated in deforested areas as the vector responsible for the transmission of CL 21,23 . However, the species abundance observed in most households in urban environments, in view of the observations of FERNÁNDEZ et al (2012) 6 in areas of relatively low active transmission, leads us to conclude that there is little probability of transmission of the disease in our study area.…”

SUMMARY The first Argentinian autochthonous human case of visceral leishmaniasis (VL) was confirmed in Posadas (Misiones) in 2006. Since then, the disease has increased its incidence and geographical distribution. In the 2006-2012 period, 107 human cases were detected (11 deaths). The presence of Lutzomyia longipalpis was detected in peridomiciles in Puerto Iguazú urban area in 2010; some of these findings were associated with households where cases of canine VL had already been reported. The objective of this study was to ascertain the abundance and spatial distribution of Lu. longipalpis in Puerto Iguazú City, on the Argentina-Brazil-Paraguay border. Lu. longipalpis proved to be exclusively urban and was found in 31% of the households sampled (n = 53), 67% of which belonged to areas of low abundance, 20% to areas of moderate abundance and 13% to areas of high abundance. Nyssomyia whitmani was the only species found both in urban and peri-urban environments, and Migonemyia migonei was registered only on the outskirts of the city. Due to the fact that Puerto Iguazú is considered to be at moderate risk at the moment, it is necessary to intensify human and canine case controls, as well as take integrated prevention and control measures regarding the environment, vectors and reservoirs on the Argentina-Brazil-Paraguay border area.

“…In the absence of bibliographic references, the 44 ; Martins Netto et al 45 ; Oliveira-Neto et al 46 Percentage of effectiveness transition probability was assumed. The probability of being diagnosed with cutaneous leishmaniasis was estimated based on the results of two investigations made on two outbreaks in the provinces of Tucuman and Misiones, northern Argentina, during 2003 and 2004 15,16 (unpublished data used for the estimation). The probability of being diagnosed was assumed unchanged during interepidemic periods, given that the surveillance system was maintained active through local training and periodic evaluation after these investigations.…”

Cost-effectiveness of prevention strategies for American tegumentary leishmaniasis in Argentina

The aim of this study was to estimate the cost-effectiveness of reducing tegumentary leishmaniasis transmission using insecticide-impregnated clothing and curtains, and implementing training programs for early diagnosis. A societal perspective was adopted, with outcomes assessed in terms of costs per disability adjusted life years (DALY). Simulation was structured as a Markov model and costs were expressed in American dollars (US$). The incremental cost-effectiveness ratio of each strategy was calculated. One-way and multivariate sensitivity analyses were performed. The incremental cost-effectiveness ratio for early diagnosis strategy was estimated at US$ 156.46 per DALY averted, while that of prevention of transmission with insecticide-impregnated curtains and clothing was US$ 13,155.52 per DALY averted. Both strategies were more sensitive to the natural incidence of leishmaniasis, to the effectiveness of mucocutaneous leishmaniasis treatment and to the cost of each strategy. Prevention of vectorial transmission and early diagnosis have proved to be cost-effective measures.
