Determinación de la resistencia a insecticidas organofosforados, carbamatos y piretroides en tres poblaciones de Anopheles albimanus (Diptera: Culicidae) de Panamá

Malaria remains the deadliest vector-borne disease in the world. With nearly half of the world's population at risk, 216 million people suffered from malaria in 2016, with over 400,000 deaths, mainly in sub-Saharan Africa. Important global efforts have been made to eliminate malaria leading to significant reduction in malaria cases and mortality in Africa by 42% and 66%, respectively. Early diagnosis, improved drug therapies and better health infrastructure are key components, but this extraordinary success is mainly due the use of long-lasting insecticidal nets (LLINs) and indoor residual sprayings (IRS) of insecticide. Unfortunately, the emergence and spread of resistance in mosquito populations against insecticides is jeopardising the effectiveness of the most efficient malaria control interventions. To help establish suitable resistance management strategies, it is vital to better understand the distribution of resistance, its mechanisms and impact on effectiveness of control interventions and malaria transmission. In this chapter, we present the current status of insecticide resistance worldwide in main malaria vectors as well as its impact on malaria transmission, and discuss the molecular mechanisms and future perspectives.

“…En las regiones indígenas, donde habita solamente el 12 % de la población del país, se registra más del 85 % del total de los casos de malaria diagnosticados a nivel nacional (5). Estas zonas endémicas se localizan en las cercanías de las regiones fronterizas de Panamá con Costa Rica y Colombia (6 (2009)(2010)(2011)(2012)(2013), en estas regiones endémicas que ocupan el 38,6 % del territorio nacional y tienen una población de 858.121 habitantes (7), se registraron 3.099 casos de malaria, con un promedio anual de 620 casos.…”

“…El paludismo es causado principalmente por P. vivax, que se registra en casi el 90 % de los casos diagnosticados (2). En las regiones indígenas es donde se diagnostica más del 85 % del total de los casos a nivel nacional y en ellas habita solamente el 10 % de la población total del país (10,13). Igualmente, estas zonas endémicas se focalizan cercanas a las regiones interfronterizas de Panamá con Costa Rica y Colombia.…”

ARTÍCULO ORIGINAL Biomédica 2012;32:557-69 doi: http://dx.doi.org/10.7705/biomedica.v32i4.773 Caracterización de la transmisión de la malaria por Plasmodium vivax en la región fronteriza de Panamá con Costa Rica en el municipio de Barú, Panamá Characterization of Plasmodium vivax malaria transmission at the border of Panamá and Costa RicaIntroduction. Few studies have described the factors associated with Plasmodium vivax transmission dynamics in endemic regions from Panamá. Objective. Malaria transmission dynamics produced by P. vivax were characterized at the border between Panamá and Costa Rica. Materials and methods. In the municipality of Barú, an observational, descriptive and cross-sectional study was undertaken to measure the annual parasite index (API), slide positivity index (SPR), and the annual blood examination rate (ABER). The most frequent symptoms and signs in malaria patients were recorded. The anopheline species were identified in the area and the preferred larval habitats, the density of larval populations in the larval habitats and the bites/human/night were characterized. Results. Of a total of 10,401 thick smear blood samples, 83 were positive for P. vivax. Of these, 84% came from rural areas and 79% were from economically active individuals. The median and average ages were 36 and 30 years, respectively, and 58.5% of the malaria cases were male. API was 4.1/1,000 inhabitants; SPR was 0.8% and ABER was 51.9%. Of the diagnosed cases, 54% showed blood parasitemias ranging between 100-2,000 parasites/µl. The majority of the cases were observed in May and June. Two mosquito vector species were identified--Anopheles albimanus and An. punctimacula. Conclusion. These observations indicate the advisibility of continued entomological studies, strengthening of epidemiological surveillance, consideration of additional risk factors and evaluation
