ABSTRACT

Introducción: A nivel mundial, Aedes aegypti es el culícido más importante en cuanto a la transmisión de arbovirus de impacto en salud pública. Objetivo: Profundizar en los conocimientos ecológicos de Ae. aegypti en República Dominicana, a través de los recipientes o contenedores que utiliza para desarrollar sus formas preimaginales. Métodos: El estudio se extendió desde octubre a diciembre de 2017. Se muestrearon aleatoriamente 100 viviendas, en las que se revisaron todos los recipientes con potencialidad para albergar larvas y/o pupas de mosquitos, dentro y fuera del domicilio. Se cuantificó el tipo y total de cada depósito positivo según su ubicación en cada vivienda, para calcular el porcentaje de representatividad, junto al Índice Pupal por Depósitos específicos (IPDe) para cada receptáculo con pupas. Resultados: Se detectó presencia de Ae. aegypti en el 41 por ciento de las casas visitadas. De los 419 recipientes analizados, 74 resultaron positivos a larvas y/o pupas (17,66 por ciento). Se clasificaron 28 tipos de depósitos atendiendo a su función y material. Cuantitativamente, los depósitos permanentes fueron los más representativos con un 54,05 por ciento. Las mayores capturas se realizaron en el peridomicilio. El tanque plástico fue el más relevante, pues aportó el 28,37 por ciento del total de depósitos positivos, así como un elevado IPDe. Conclusiones: Los resultados evidencian elevados niveles de infestación en los domicilios de Jarabacoa que deben ser controlados a fin de disminuir el riesgo en la transmisión de arbovirosis. El control de los recipientes artificiales, como los contenedores desechables, los neumáticos y sobre todo los tanques de agua, es la piedra angular de cualquier esfuerzo para prevenir estas enfermedades(AU)


Introduction: Aedes aegypti is the most important culicid worldwide in terms of transmission of arbovirus infections of a high impact on public health. Objective: Broaden ecological knowledge about Aedes aegypti in the Dominican Republic, particularly about the containers and other sites where immature development occurs. Methods: The study extended from October to December 2017. One hundred households were randomly surveyed, checking all the containers with a potential to host mosquito larvae and/or pupae both inside and outside the house. Quantification was made of the type and total of positive containers according to their location in each household, to estimate the percentage of representativeness and the pupal index per container identified (PICI) when pupae were found in them. Results: Aedes aegypti was found to be present in 41 percent of the houses visited. Of the 419 containers analyzed, 74 were positive for larvae and/or pupae (17.66 percent). Containers were classified into 28 types according to their function and material. Quantitatively, permanent containers were the best represented with 54.05 percent. The largest captures were made in the area around the house. Plastic water tanks were the most relevant, with 28.37 percent of the total positive containers and a high PICI. Conclusions: Results show high levels of infestation in Jarabacoa households. These should be controlled to reduce the risk of arbovirus infection transmission. Control of artificial breeding sites, such as disposable containers, tires and especially water tanks, is the cornerstone of any effort to prevent these diseases(AU)

ABSTRACT

Abstract Mosquitoes (Diptera: Culicidae) are important vectors of diverse pathogenic organisms, particularly arboviruses and protozoa. The immature stages of mosquitoes occur in a wide range of natural or human-made aquatic habitats. On this basis, some anthropogenic places such as cemeteries, usually serve as thrive and productive artificial-breeding habitats for mosquitoes. Despite being important foci for vector species, urban cemeteries are frequently overlooked in control and surveillance programs. This study evaluates the association of ecological variables and attributes (type of material, presence of flowers, water availability and height from the ground) of the breeding sites with the levels of infestation of mosquito immature stages. In 2017, an entire urban cemetery in Jarabacoa (Dominican Republic) was sampled at two different climatic periods (March: dry and August: rainy) for the characterization of the artificial breeding-sites, collection of immature stages of culicids and subsequent laboratory rearing for species identification. In total 968 containers were studied, containing 7 758 immature stages in 203 (21.0 %) water-filled containers which accounted for four species: Culex quinquefasciatus (50.5 %), Aedes aegypti (47.1 %), Aedes albopictus (1.9 %) and Culex nigripalpus (0.4 %). The mean of A. aegypti immatures in infested containers was roughly two times higher compared to C. quinquefasciatus and significantly lower compared to A. albopictus. The total Container Index (CI) was 20.9 %, and among the type of materials, those made from rock (cement, ceramic, and mud) and plastic had the highest CI = 25.9 % and 23.4 %, respectively. Almost 95 % of the total infested water-filled containers were made of plastic or rock. No association was found between the type of material of the containers and the density of mosquitoes. However, overall, greater densities of immature stages were found at ground than at higher levels. A weak positive correlation between water volume and density was found in some species of immature stages. Significantly higher number of C. quinquefasciatus were recorded in containers with flowers and large water volume. In contrast, A. aegypti immature stages were more frequent in containers without flowers. A weak negative association between water volume and infestations was found for A. albopictus immatures. As reflected of their opportunistic behaviour and broad ecological plasticity, Culex spp. and Aedes spp. mosquitoes were abundant pests in cemetery habitats where were able to breed in almost any kind of water-filled container regardless the type of material. However, our study showed that some ecological variables have critical impact for the development of the immature stages of some species. The health authorities and cemetery keepers can benefit from these results by focusing on the implementation of detailed plans and integrated strategies for the control and prevention of cemetery infestations by mosquitoes.(AU)


Resumen Los mosquitos (Diptera: Culicidae) son importantes vectores de diversos organismos patógenos, tales como arbovirus y protozoos. Los estadios inmaduros de los mosquitos pueden encontrarse en un amplio abanico de hábitats, tanto de origen natural como humano. Algunos lugares antrópicos, como los cementerios, sirven como prósperos hábitats artificiales para el desarrollo del ciclo de vida de los mosquitos. A pesar de constituir importantes focos para especies de interés vectorial, los cementerios urbanos son frecuentemente olvidados en los programas de vigilancia y control. Este estudio evaluó la asociación de algunas variables ecológicas (tipo de material, presencia de flores, disponibilidad de agua, y altura respecto al suelo) de los lugares de cría (recipientes) con los niveles de infestación de las fases preimarginales de los culícidos. En 2017, un cementerio urbano en Jarabacoa (República Dominicana) fue inspeccionado durante dos periodos climáticos (es decir: marzo: estación seca y agosto: estación húmeda) para: caracterizar los lugares de cría artificiales, captura de los estadios inmaduros de culícidos e identificación de los adultos emergidos a partir de las fases inmaduras. En total, 968 recipientes fueron examinados, conteniendo 7 758 inmaduros en 203 (21.0 %) recipientes con agua pertenecientes a cuatro especies, Culex quinquefasciatus (50.5 %), Aedes aegypti (47.1 %), Aedes albopictus (1.9 %) y Culex nigripalpus (0.4 %). El índice de recipiente (IR) fue del 20.9 %, y los recipientes fabricados a partir de roca (cemento, cerámica y barro) y plástico tuvieron el mayor IR = 25.9 y 23.4 %, respectivamente. Casi un 95 % de los recipientes con agua infectados estaban constituidos de materiales tipo plástico o roca. No se encontró asociación entre el tipo de material del recipiente y la densidad. En general, mayor densidad de estadios inmaduros fue observada a nivel del suelo que a alturas mayores. Se observó un incremento significativo del número de C. quinquefasciatus en recipientes con flores y grandes volúmenes de agua. Por el contrario, los estadios de A. aegypti fueron más frecuentes en recipientes sin flores. Como reflejo de su comportamiento oportunista y amplia plasticidad ecológica, los mosquitos Culex y Aedes fueron abundantes en los cementerios, siendo capaces de desarrollar su ciclo de vida acuático en cualquier tipo de recipiente, con independencia del material que lo constituya. Nuestro estudio, por tanto, mostró que algunas variables ecológicas tienen un impacto crítico sobre el desarrollo de los estadios inmaduros de algunas especies de mosquitos. Tanto las autoridades de salud pública como los cuidadores del cementerio pueden beneficiare de estos resultados centrándose en la implementación de planes detallados y estrategias integradoras para el control y prevención de mosquitos que infectan cementerios.(AU)

ABSTRACT

INTRODUCTION: dengue and its lethal form, that is, dengue hemorrhagic fever, has significantly increased in Las Americas, being the Aedes aegypti the main and the only transmitting vector till now. OBJECTIVE: to evaluate the effectiveness of K-Othrine WG250 (deltamethrin) in residual (perifocal) applications in rest sites and in breeding sites of Aedes aegypti. METHODS: from February to June 2011, a perifocal residual treatment was applied in San Juan de Dios people's council of "José Martí" university polyclinic in Camaguey. It was directed to rest and breeding sites of the vector, for which several areas comprising different number of non-adjacent and randomly chosen houses, with high and similar rates of infestation in the period before the treatment, were selected. The application of this treatment was based on the use of IKA-9 hand sprayers at a dose of 1 g/l of water, with fitted conical nozzle for three areas and with flat nozzles 80-02 in the other three areas to deposit 25 mg ia/m2. Focality was monitored 5 months before the applications and 3 months afterwards by means of entomological surveys conducted in the selected universe of houses. RESULTS: the number of foci was reduced to 0 in the first month after the application if compared to the existing number before the treatment and with both types of nozzles. Fifteen positive reservoirs were reported in June, mainly low water tanks located outside the house. CONCLUSIONS: this product showed high effectiveness for 3 months in the Aedes aegypti control as part of the residual (perifocal) treatment. Therefore, it should be considered as an alternative in the surveillance and control strategies aimed at this vector.

ABSTRACT

INTRODUCTION: Malaria is a serious public health problem at present; it affects almost half of the population from over 100 countries and poses a high risk of reintroduction in Cuba. OBJECTIVE: To identify the Culicidae species present in natural breeding sites located in three areas of Camagüey municipality, particularly anopheles. METHODS: Larval inspections were carried out in 66 natural breeding sites of Anopheles almimanus located in three areas of Camagüey municipality from May to June 2010, according the World Health Organization methodology. The preferential breeding sites of Anopheles albimanus and the association of this species with other Culicidae were ascertained. RESULTS: Presence of Culicidae in 28.78% of inspected breeding sites, being Anopheles albimanus the prevailing one with 63.51%. This species was captured together with Culex quinquefasciatus, Culex nigripalpus, Culex erraticus, Culex corniger, Psorophora confinnis, Psorophora howardii and Ochlerottatus scapularis, in low polluted water bodies such as lagoons (58.34%) and streams (25%), and in others more polluted such as ditches (8.33%) and narrow trails (8.33%). CONCLUSIONS: The existence of species of medical and veterinary importance, particularly Anopheles albimanus, in the studied areas calls for constant monitoring of these species in order to draw up integrated strategies focused on the biological fight, and the involvement of the community in this process to help in preventing the emergence of cases or epidemic outbreaks of imported malaria.

ABSTRACT

The sandfly Phlebotomus perniciosus is the most widespread vector of Leishmania infantum in Spain. Laboratory colonisation represents the most feasible source of information on the biology of these insects, but in conducting any study, the density of individuals in the colony may drop to such an extent that it is sometimes difficult to recover the initial population levels. A new technique was tested for the recovery of sandfly eggs in three different colonies; the recovery rate was studied by comparing the standard method of mass rearing with this new method of colony management. The results demonstrate a mean increase of 18.4% in adult production, a growth in colony productivity that justifies the inclusion of this process in the routine maintenance of any colony of sandflies.

ABSTRACT

Los crecientes brotes de dengue complejiza la ya deteriorada situación epidemiológica mundial, lo cual se favorece por la presencia de macrofactores condicionantes para la transmisión. Objetivo: evaluar los resultados entomológicos durante el control de un caso de dengue introducido en Camagüey en julio de 2010. Métodos: se realizó un estudio descriptivo longitudinal retrospectivo, para referir las principales acciones entomológicas, así como su efectividad en el control del evento epidemiológico. Resultados: los valores de los índices aédicos estuvieron por encima de lo permisible en los tres primeros ciclos de trabajo, con altos valores del Indice Breteau en comparación con el Indice Casa, por lo que hubo dispersión de la especie. El control de calidad municipal aportó las mayores colectas, con una proporción de una muestra larval/20,3 viviendas inspeccionadas y una muestra de adulto/426,5 viviendas inspeccionadas. Se destacan tanques bajos, cisternas y toneles con la mayor presencia del vector, siendo el 52,63 % permanentes, útiles y no modificables según criterio de la población. De haber ejecutado la población el autofocal familiar, se pudo evitar el 89,47 % de los depósitos positivos. Dos manzanas repitieron en dos ocasiones y otras dos tres veces. Conclusiones: las experiencias acumuladas en el tratamiento focal y adulticida, demostraron ser eficaces en el control antivectorial ante la notificación del caso dengue introducido, lo que junto al apoyo de la extrasectorialidad, resultó ser clave en el enfrentamiento exitoso del evento en el menor tiempo posible (AU)


The growing outbreaks of dengue complicate the deteriorated epidemiologic worldwide situation, which is favored by the presence of determining macrofactors for transmission. Objective: to evaluate the entomological results during the control of a dengues case introduced into Camagüey in July 2010. Methods: a descriptive longitudinal retrospective study was performed, in order to refer the main entomological actions, as well as its effectiveness in the control of the epidemiologic event. Results: values of Aedes´index were beyond of what is permissible in the first three cycles of work, with high values of Breteau rate compared to House rate that is why there was species´ dispersion. The municipal quality control contributed to greater collections, with a proportion of a larval sample/20,3 inspected houses and adult's sample/426,5 inspected houses. Low tanks, cisterns and barrels with the vector stands out, being the 52,63 % permanent, useful and no modifiable according to the population's opinion. If the population were carried out family inspection, 89,47 % of positive water tanks could be avoided. Two blocks repeated in two occasions and another two or three times. Conclusions: gained experiences in the focal treatment, proved to be efficacious in the anti-vectorial control in the faced of the notification of a case of dengue introduced, which together with extrasectorial support, it turned out to be key in the successful confrontation of the event in the short possible time (AU)

ABSTRACT

INTRODUCCION: el control de los sitios de cría de mosquitos de relevancia médica es esencial en los programas de lucha antivectorial, sin embargo, los esfuerzos ejecutados hasta la actualidad no han sido suficientes por el aumento paulatino de casos confirmados de fiebre de dengue. OBJETIVO: informar sobre los principales sitios de cría de Aedes aegypti, en un ambiente urbano de Camagüey con baja densidad del vector. MÉTODOS: el universo urbano se inspeccionó en su totalidad entre enero y diciembre de 2007. En los depósitos positivos la colecta fue según metodología del Programa Nacional de Control de Vectores. Cada depósito fue caracterizado mediante una planilla de investigación de manzana positiva implementada al efecto. Se determinó el porcentaje de representatividad de cada depósito positivo, así como la proporción de larvas por cada depósito. RESULTADOS: Aedes aegypti colonizó 44 depósitos diferentes con destaque para artificiales (97,73 por ciento). La mayoría fueron permanentes, útiles y no modificables. Siguiendo el criterio de la población la combinación permanentes + útiles se cumple en 17 tipos de depósitos que representan 38,63 por ciento, y aportan un total de 180 recipientes positivos para 81,08 por ciento. Los tanques bajos contribuyeron a 36,03 por ciento de la positividad. CONCLUSIONES: la elevada positividad en depósitos que pudieron ser evitados por la población obliga a elevar la responsabilidad individual en el mejoramiento del saneamiento doméstico y, con ello, la concientización cívica para alcanzar una activa participación comunitaria en este sentido. Esto junto al fortalecimiento de la transectorialidad, permitirá impactar en la eliminación y disposición final de todo material inservible y que pueda servir de criadero a los mosquitos.


INTRODUCTION: the control of the breeding sites of mosquitoes of medical importance is essential for the anti-vector fighting programs; however, the efforts made so far have not great enough since the confirmed dengue fever cases gradually increase. OBJECTIVE: to provide information on the main breeding sites of Aedes aegypti in an urban area with low vector density in Camagüey province. METHODS: the urban universe was fully surveyed from January to December 2007. The collection procedure in the positive containers followed the National Vector Control program methodology. The characteristics of each container were written in a customized study form of positive blocks. The representative percentage of each positive container, as well as the proportion of larvae per container were determined. RESULTS: Aedes aegypti formed colonies in 44 different containers, being the artificial reservoirs the predominant ones (97.73 percent). The majority were permanent, useful and unchangeable. Following the population's criteria, the combination of permanent plus useful is valid in 17 types of containers accounting for 38.36 percent and contributing 180 positive containers for 81.08 percent of the total number. The tanks placed on the ground reached 36.03 percent positivity. CONCLUSIONS: the high number of mosquito-positive tanks demands greater individual responsibility in improving domestic sanitation and thus, the increase of awareness in order to achieve more active community involvement in this regard. The latter together with the strengthening of transectoriality will allow having an impact on the elimination and final disposal of all the useless materials that may serve as possible breeding sites of mosquitoes.

ABSTRACT

Los crecientes brotes de dengue complejiza la ya deteriorada situación epidemiológica mundial, lo cual se favorece por la presencia de macrofactores condicionantes para la transmisión. Objetivo: evaluar los resultados entomológicos durante el control de un caso de dengue introducido en Camagüey en julio de 2010. Métodos: se realizó un estudio descriptivo longitudinal retrospectivo, para referir las principales acciones entomológicas, así como su efectividad en el control del evento epidemiológico. Resultados: los valores de los índices aédicos estuvieron por encima de lo permisible en los tres primeros ciclos de trabajo, con altos valores del Indice Breteau en comparación con el Indice Casa, por lo que hubo dispersión de la especie. El control de calidad municipal aportó las mayores colectas, con una proporción de una muestra larval/20,3 viviendas inspeccionadas y una muestra de adulto/426,5 viviendas inspeccionadas. Se destacan tanques bajos, cisternas y toneles con la mayor presencia del vector, siendo el 52,63 % permanentes, útiles y no modificables según criterio de la población. De haber ejecutado la población el autofocal familiar, se pudo evitar el 89,47 % de los depósitos positivos. Dos manzanas repitieron en dos ocasiones y otras dos tres veces. Conclusiones: las experiencias acumuladas en el tratamiento focal y adulticida, demostraron ser eficaces en el control antivectorial ante la notificación del caso dengue introducido, lo que junto al apoyo de la extrasectorialidad, resultó ser clave en el enfrentamiento exitoso del evento en el menor tiempo posible.


The growing outbreaks of dengue complicate the deteriorated epidemiologic worldwide situation, which is favored by the presence of determining macrofactors for transmission. Objective: to evaluate the entomological results during the control of a dengue’s case introduced into Camagüey in July 2010. Methods: a descriptive longitudinal retrospective study was performed, in order to refer the main entomological actions, as well as its effectiveness in the control of the epidemiologic event. Results: values of Aedes´index were beyond of what is permissible in the first three cycles of work, with high values of Breteau rate compared to House rate that is why there was species´ dispersion. The municipal quality control contributed to greater collections, with a proportion of a larval sample/20,3 inspected houses and adult's sample/426,5 inspected houses. Low tanks, cisterns and barrels with the vector stands out, being the 52,63 % permanent, useful and no modifiable according to the population's opinion. If the population were carried out family inspection, 89,47 % of positive water tanks could be avoided. Two blocks repeated in two occasions and another two or three times. Conclusions: gained experiences in the focal treatment, proved to be efficacious in the anti-vectorial control in the faced of the notification of a case of dengue introduced, which together with extrasectorial support, it turned out to be key in the successful confrontation of the event in the short possible time.

ABSTRACT

INTRODUCCION: el control de los sitios de cría de mosquitos de relevancia médica es esencial en los programas de lucha antivectorial, sin embargo, los esfuerzos ejecutados hasta la actualidad no han sido suficientes por el aumento paulatino de casos confirmados de fiebre de dengue. OBJETIVO: informar sobre los principales sitios de cría de Aedes aegypti, en un ambiente urbano de Camagüey con baja densidad del vector. MÉTODOS: el universo urbano se inspeccionó en su totalidad entre enero y diciembre de 2007. En los depósitos positivos la colecta fue según metodología del Programa Nacional de Control de Vectores. Cada depósito fue caracterizado mediante una planilla de investigación de manzana positiva implementada al efecto. Se determinó el porcentaje de representatividad de cada depósito positivo, así como la proporción de larvas por cada depósito. RESULTADOS: Aedes aegypti colonizó 44 depósitos diferentes con destaque para artificiales (97,73 por ciento). La mayoría fueron permanentes, útiles y no modificables. Siguiendo el criterio de la población la combinación permanentes + útiles se cumple en 17 tipos de depósitos que representan 38,63 por ciento, y aportan un total de 180 recipientes positivos para 81,08 por ciento. Los tanques bajos contribuyeron a 36,03 por ciento de la positividad. CONCLUSIONES: la elevada positividad en depósitos que pudieron ser evitados por la población obliga a elevar la responsabilidad individual en el mejoramiento del saneamiento doméstico y, con ello, la concientización cívica para alcanzar íuna activa participación comunitaria en este sentido. Esto junto al fortalecimiento de la transectorialidad, permitirá impactar en la eliminación y disposición final de todo material inservible y que pueda servir de criadero a los mosquitos(AU)


INTRODUCTION: the control of the breeding sites of mosquitoes of medical importance is essential for the anti-vector fighting programs; however, the efforts made so far have not great enough since the confirmed dengue fever cases gradually increase. OBJECTIVE: to provide information on the main breeding sites of Aedes aegypti in an urban area with low vector density in Camagüey province. METHODS: the urban universe was fully surveyed from January to December 2007. The collection procedure in the positive containers followed the National Vector Control program methodology. The characteristics of each container were written in a customized study form of positive blocks. The representative percentage of each positive container, as well as the proportion of larvae per container were determined. RESULTS: Aedes aegypti formed colonies in 44 different containers, being the artificial reservoirs the predominant ones (97.73 percent). The majority were permanent, useful and unchangeable. Following the population's criteria, the combination of permanent plus useful is valid in 17 types of containers accounting for 38.36 percent and contributing 180 positive containers for 81.08 percent of the total number. The tanks placed on the ground reached 36.03 percent positivity. CONCLUSIONS: the high number of mosquito-positive tanks demands greater individual responsibility in improving domestic sanitation and thus, the increase of awareness in order to achieve more active community involvement in this regard. The latter together with the strengthening of transectoriality will allow having an impact on the elimination and final disposal of all the useless materials that may serve as possible breeding sites of mosquitoes(AU)

ABSTRACT

Debido a la actual situación epidemiológica mundial, es necesario determinar la presencia y distribución de especies vectoriales con prioridad en el campo de la salud pública, y con ello tomar iniciativas más atinadas en la lucha que se libra contra tan indeseables portadores de enfermedades al hombre. Objetivo: informar las especies de culícidos y moluscos de relevancia médico-veterinaria, presentes en una Área de Salud de la provincia de Camagüey, para contribuir al diseño e implementación de adecuadas estrategias de vigilancia, prevención y control, a partir de las especies reportadas. Método: se realizaron prospecciones entomológicas y malacológicas en el universo de viviendas y/o locales atendido por el Policlínico Universitario Ignacio Agramonte de Camagüey (143 manzanas, con 6 terrenos baldíos), así como en los 15 criaderos naturales y/o potenciales de mosquitos y moluscos dulceacuícolas perjudiciales para la salud del hombre. En las colectas se aplicaron las técnicas descritas por el Ministerio de Salud Pública de Cuba, para la red nacional de control de vectores. Resultados: se identificaron 22 especies con marcada relevancia médico-veterinaria, 14 de ellas pertenecen al Phylum Arthropoda: Aedes aegypti, Anopheles albimanus, An vestitipennis y Culex quinquefasciatus, así como y ocho al Phylum Mollusca: Biomphalaria helophila, Fossaria cubensis y Pomacea poeyana, todas relacionadas con la transmisión de importantes enfermedades al hombre. Discusión: las especies reportadas obligan a diseñar e implementar estrategias de vigilancia y control, destinadas a evitar la introducción y propagación de enfermedades exóticas en el territorio, pues el intercambio comercial, estudiantil y de personal especializado de salud, educación, deporte y cultura con otras regiones, va en aumento en nuestra provincia


Due to the current worldwide epidemiologic situation, it is necessary to determine the presence and distribution of vectorial species with priority in public health field, and with it to take correct initiatives against so undesirable carriers of diseases to man. Objective: to inform the culicide species and mollusks of medical-veterinary relevance, present in a Health Area of Camagüey province, contributing to the design and implementation of appropriate strategies of surveillance, prevention and control, starting from the reported species. Methods: entomological and malacological explorations in the universe of houses and/or local assisted by the University Polyclinic Ignacio Agramonte of Camagüey (143 blocks, with 6 waste lands), as well as in 15 natural and/or potentials of mosquitoes´ breeding grounds and harmful sweet-water-bearing mollusks for man's health. To the collections were applied the described techniques by the Ministry of Public Health of Cuba, for the national network of control of vectors. Results: twenty-two species were identified with marked medical-veterinary relevance which are: 14 to the Phylum Arthropoda: Aedes aegypti, Anopheles albimanus, An vestitipennis and Culex quinquefasciatus, as well as 8 to the Phylum Mollusca: Biomphalaria helophila, Fossaria cubensis and Pomacea poeyana, all related with the transmission of important diseases to the man. Conclusions: with this investigation we make known the culicide species and mollusks of medical-veterinary relevance, present in a Health Area of Camagüey province, and with it contributing knowledge that help in the design and implementation of appropriate strategies of surveillance, prevention and control, of reported species

ABSTRACT

Actualmente la gran dispersión, incidencia y gravedad de muchas enfermedades transmitidas por vectores, provoca un peligroso aumento de las mismas en varias regiones del mundo. Objetivo: evaluar el impacto de las estrategias implementadas en la Universidad Médica de Camagüey, a través del comportamiento de la abundancia y distribución de las especies de vectores detectadas. Métodos: se realizó un estudio de intervención sanitaria en la Universidad Médica de Camagüey entre octubre-2004 y abril-2007. Se aplicaron para las encuestas las técnicas descritas por el Ministerio de Salud Pública de Cuba Para los moluscos se empleó un colador de bronce, removiendo los sustratos areno-fangosos y vegetación colindante, así como colectas manuales con pinzas, mediante capturas por unidad de esfuerzo sin reposición. Se coordinó con la administración de la facultad la ejecución de acciones antivectoriales, fundamentalmente de manipulación ambiental. Resultados: inicialmente se identificaron 17 especies vectoriales, siendo los culícidos más abundantes y variados. En la etapa final prevalecieron sólo seis especies de relevancia médica (76.48 por ciento de reducción), con una importante reducción en el grupo de los mosquitos hematófagos. Conclusiones: varias especies relacionadas con importantes enfermedades de transmisión vectorial en ambientes urbanos, rurales y costeros, fueron detectados en la universidad, favorecida inicialmente por factores ambientales, operacionales, entomológicos y humanos, lo que fue revertido con la implementación de medidas coordinadas de monitoreo, control y vigilancia vectorial, actividades que se han potenciado con la educación ambientalista de estudiantes, trabajadores y comunidad en general.


Nowadays the great dispersion, incidence and seriousness of many diseases transmitted by vectors, cause a dangerous increase of them in several regions of the world. Objective: to evaluate the impact of the strategies implemented at the Medical University of Camagüey, through the behavior of abundance and distribution of species of vectors detected. Methods: a sanitary intervention study at the Medical University of Camagüey was carried out, from October 2004 to April 2007. To the surveys, techniques described by the Ministry of Health Public of Cuba were applied. For mollusks a copper colander was used, removing the arena-muddy substrates and adjacent vegetation, as well as manual collections with forceps, by means of captures by unit of effort without replacement. It was coordinated with the administration of the faculty the fulfilment of antivectorial actions, fundamentally of environmental manipulation. Results: initially 17 vectorial species were identified; the most abundant and varied were culicides. In the final stage only prevailed six species of medical relevance (76.48 percent of reduction), with an important reduction in the group of hematophagous mosquitoes. Conclusions: several species related with important diseases of vectorial transmission in urbane, rural and coastal environments were detected in the Medical University, favored initially by environmental, operational, entomologic and human factors, what was reverted with the implementation of coordinated measures of monitoring, control and vectorial surveillance, activities that had been increased with students, workers´ and community environmentalist education.
