Vulnerabilidad de la Covid-19 por estratificación epidemiológica en policlínicos de Arroyo Naranjo, La Habana / Covid-19 vulnerability due to epidemiological stratification at community clinics in Arroyo Naranjo, Havana

Introducción: El SARS-CoV-2 es un coronavirus nuevo poco conocido, su puerta de entrada es la respiratoria. La vulnerabilidad espacial establece grados de riesgos para contraer la enfermedad, esto permite aplicar intervenciones radicales y diferentes, necesarias para enfrentar la pandemia. Objetivo: Determinar la vulnerabilidad espacial de la Covid-19 en policlínicos de Arroyo Naranjo, La Habana. Método: Se realizó un estudio descriptivo y transversal. Las siete áreas de salud del municipio Arroyo Naranjo. Con una población territorial. Se estudiaron adultos de 60 años y más, casos positivos y mortalidad por Covid-19, con infección respiratoria aguda, sintomatología y vulnerabilidad espacial. Los policlínicos se estratificaron en contextos vulnerables, medianamente vulnerables y menos vulnerables. La estratificación epidemiológica se realizó mediante el método de indicadores con ponderación fija, establecidos según criterios de expertos. Los datos se obtuvieron del departamento de estadística de los policlínicos y de la pesquisa diaria. Resultados: Los policlínicos estratificados como de contexto menos vulnerable fueron Capri, Managua y Eléctrico; mientras que como contexto medianamente vulnerable fueron Los Pinos, Mantilla y Grimau y de contexto vulnerable resultó el policlínico Párraga. Conclusiones: Existieron contextos vulnerables en el territorio, con una influencia negativa de los indicadores no bien controlados que favorecen la aparición de la Covid-19, lo que expresa el peligro de contraer la enfermedad o de un rebrote(AU)

Introduction: SARS-CoV-2 is a little-known new coronavirus, its entry point is the respiratory way. The spatial vulnerability establishes degrees of risks to contract the disease, this allows the application of radical and different interventions, necessary to face the pandemic. Objective: To determine Covid-19 spatial vulnerability at polyclinics in Arroyo Naranjo, Havana. Method: A descriptive and cross-sectional study was carried out in the seven health areas at Arroyo Naranjo municipality, with territorial population. We studied adults aged 60 years and over, positive cases and mortality from Covid-19, with acute respiratory infection, symptoms and spatial vulnerability. The community clinics were stratified into vulnerable, moderately vulnerable and lesser vulnerable contexts. Epidemiological stratification was carried out using the method of indicators with fixed weights, established according to expert criteria. Data were obtained from the statistics department of the clinics and from the daily survey. Results: The community clinics stratified as having less vulnerable context were Capri, Managua and Eléctrico; while Los Pinos, Mantilla and Grimau were a moderately vulnerable context and Párraga clinic resulted as a vulnerable context. Conclusions: There were vulnerable contexts in the territory, with a negative influence of poorly controlled indicators that favor the appearance of Covid-19, which expresses the danger of contracting the disease or a regrowth(AU)

Assessment of Temperature Variability Effect on Rice Production in Nasarawa State, Nigeria

The output of cereal farmlands is imperative for sustainable global food security. Quantity of production from cereal croplands are partly a function of climatic elements and are connected to the pulses of climatic variation. Hence, this paper assessed temperature variability effect on rice production in Nasarawa State, Nigeria. Daily maximum and minimum temperature data were obtained from the Nigerian Meteorological Agency and converted into monthly averages while annual rice production data was obtained from the office of Nasarawa State’s Agricultural Development Programme. Acquired data were analysed using Linear Multiple Regression Model, coefficient of variation and spatial data analysis techniques. Although rice production in the State is being affected by the fluctuations in both minimum and maximum monthly temperature, the later poses grave concern for sustainability of rice production with a negative effect size of -3.145 and a coefficient value of -191,324.30 metric tons. This negative impact of maximum temperature fluctuations on rice production indicates that rice production in Nasarawa State is vulnerable to climate variability with increasing maximum temperature. LGAs in the south senatorial district has more favourable locations for rice production in comparison to those in the North and West districts given that less temperature fluctuation was observed in the former. Government and non-governmental institutions as well as individuals planning to establish rice farm project(s) in the study area should consider doing so in the South Senatorial District in order to avoid the adverse effect of temperature variability.
