    Japanese Encephalitis: Assessing disease risk due to landscape factors at multiple scales

    Get PDF
    Japanese Encephalitis is a mosquito-borne disease and is the leading cause of viral encephalitis in Asia. In many Asian countries, the geographical distribution of JE is dependent on a variety of human-environment interactions that can be conceptualized as a complex social-ecological system. The JE transmission cycle is influenced by a few primary human-landscape factors; the abundance and the spatial configuration of rice paddy fields (which provide habitat for the vector), the distribution of pig farms (which position the virus\u27 amplifying host), and the location of a susceptible human population. Our models integrate population dynamics, landscape characteristics, and weather variables that influence the spatiotemporal risk of contracting the JE virus. At a geographically small scale, we highlight regions within the geographic distribution of the disease that are of high-risk in the near future. An individual-level model was also developed to assess disease risk at a larger geographic scale. Model output reproduced the spatial and temporal dynamics of Japanese Surveillance data obtained from the World Health Organization. Such a model can be used to assess various scenarios that examine the spatial epidemiology of Japanese Encephalitis

    Risk Factors Associated with the Contraction of Ebola Virus Disease in Liberia

    Ebola virus disease (EVD) is a highly transmittable disease with high mortality rate. The purpose of this study was to examine risk factors associated with the contraction of EVD in Liberia. A retrospective cross-sectional design was used to analyze secondary data collected on 1,658 patients admitted to Ebola treatment units in Liberia, using the social ecological model as a theoretical framework. Descriptive statistics and the chi-square test for association and logistic regression were used to analyze the data. The findings of this study revealed that funeral attendance, exposure to body fluids, and contact with a living sick person were associated with the contraction of EVD (p \u3c 0.05). The likelihood of contracting EVD is 14.32 times greater among patients exposed to body fluids. The likelihood of contracting EVD is 15.34 times greater among patients exposed to a living sick person. The results failed to identify other factors such as gender, age, and community of residence as factors associated with the contraction of EVD. The findings of this study may foster social change through comprehensive EVD prevention and control programs by focusing on improving the quality of life of underprivileged communities, investing in social, educational, and community-based development programs such as roads, schools, sanitation, and health care facilities. Educational and community-based initiatives can encourage health and wellness by educating communities about the dangers EVD poses to their lives and well-being

    Autism is defined as neurology disorder affecting brain functionalities so that resulting communication, social interaction, behavior difficulties and the symptom appears before age 3. This study is aimed at understanding the factors related to autism cases in Rumah Autis Bekasi. Methods: There variables in this study namely, independent variable was immunization and dependent variable was autism and confounding variable were genetic, parents’ age, maternal health history during pregnancy, and medication during pregnancy. Primary data collected through questionaire and interview to the families of autism. This is a case study on 60 samples divided into 30 samples of autism in Rumah Autis and 30 samples of normal people living nearby with the proportion 1:1. The data were analyzed using univariate, bivariate using chi square test, and multivariate statistical analysis using regresi logistic. The results show that there is no correlation between immunization history and the autism with p-value 0.774>0.05. There is a correlation between the father’s age and the autism with p-value 0.038<0.05 and OR 0.333,there is a significant relationship between maternal health history and autism with p-value 0.038<0.05 and OR 3.763 and multivariate analysis shows that the most dominant variable is maternal health history with p-value 0.019 and OR 13.496. This study suggests that the pregnant women should check up their condition if there are some health problems and taking medication without doctor’s prescription.

    Introduction: Ergonomics good work is important so that workability, efficiency and a high level of clinical treatment can be maintained throughout the working life of a dentist. The success of the application ensures high productivity, avoid illness and injury, and improve satisfaction among dentist. On the other hand, the application of which is not suitable can cause musculoskeletal disorders related to work. MSD prevalence of dentists in the world is quite high, in India 78%, and Turkey reached 94%. The aim of the study was to determine the relationship between the dentist’s working posture and levels of glucose on the risk of MSD among dentist in the Surabaya Health Center. Method: The study design was an analytical observational with cross sectional approach conducted at the working dentist, filled maxillary posterior teeth. The sampling technique was using cluster random sampling with sample number of 19 subjects. RULA method was used to analyzed working posture of the subject while MSD complaint were recorded using Nordic Body Map. Data are coded and entered into the tabulation prior to analysis using a statistical test to see the correlation. Basic statistics are calculated, including the prevalence rate. Results and discussion: There was a relationship between the glucose levels with Nordic Body Map with significant value p= 0.025. While the significant relationship between the Dentist’t working posture and Nordic Body Map was p=0.012
