Malaria Epidemiology

Abstract Malaria risk and endemicity is often associated with the nature of human habitation and living environment. The disappearance of malaria from regions where it had been endemic for centuries, such as coastal areas of southern England, has been attributed, at least in part, to improvement in the quality of housing. Moreover, indigenous malaria transmission ceased throughout England without the necessity to eliminate the vector mosquitoes. The principles of malaria transmission, as formulated following the thinking of the pioneers of malaria epidemiology, Ronald Ross and George Macdonald, show how this may happen. Malaria ceases to be sustainable where its reproduction number, R0, the number of new cases generated on average for each existing case of malaria, falls below 1. In the terms of a Ross/Macdonald analysis the reduced contact between humans and blood-feeding mosquitoes that is achieved through housing that is secure against mosquito entry can have a powerful effect in reducing malaria R0. The island of Sri Lanka, where malaria had been endemic probably for centuries previously, has reported no indigenous cases of malaria since 2012. The disappearance of malaria from Sri Lanka followed an effective attack upon malaria transmission by the Sri Lanka Anti Malaria Campaign. The targeted and enhanced efforts of this campaign launched in 1999, drove the malaria R0 below 1 for most of the period up to 2012, leading to a nearly continuous decline in malaria cases until their extinction. The decades leading up to the launch of these efforts were ones of general improvement of living environment and notably in the quality of housing stock. Studies in the late 1980s had shown that quality of housing in a highly malarious district of Sri Lanka was a strong determinant of malaria risk. Through its effects on malaria R0, improved housing is likely to have facilitated the malaria control and cessation of indigenous malaria transmission in Sri Lanka and that it will help reduce the risk of the re-introduction of malaria to the island.

В статье изложены результаты полевых социологических исследований по проблемам оценки горожанами градостроительных проблем и городской среды в г. Тамбове в 2008 и 2020 гг. Показано, что количественный состав жителей г. Тамбова в последние 30 лет остается стабильным, при возросшем жилищном фонде за это время на 1 жителя с 14,1 м до 29,6 м. Из 75 городов России г. Тамбов находится, на основании мнений тамбовчан, на 36-м месте по качеству жизни. Актуальность статьи обусловлена научным интересом к проблеме взаимодействия горожан со средой обитания и формирования комфортной городской среды. Целью статьи является срез субъективного мнения горожан о градостроительных проблемах и условиях формирования оптимальной среды проживания. По результатам опросов установлены основные негативные факторы городской среды, в частности, плохая экология, отсутствие благоустройства. Названы предпочитаемые и нежелательные районы города для проживания. На основе ответов респондентов сформирован «социальный заказ» по оптимизации городской среды, решению градостроительных проблем. Показано, что приобщение населения к решению городских проблем повышает социальную ответственность горожан за создание комфортной среды проживания. На основании эмпирического исследования делается вывод о том, что для создания благоприятной городской среды обитания в самих горожанах должны появиться градостроительное сознание и культура с человеческим измерением. The paper presents the results of field sociological research on the problems of assessing urban planning problems and urban environment in Tambov in 2008 and 2020. The research shows that the quantitative composition of Tambov inhabitants in the last 30 years remains stable, but the housing stock during this time increased from 14.1 m to 29.6 m per inhabitant. Tambov is ranked 36th out of 75 cities in Russia in terms of quality of life according to the opinions of Tambov residents. The relevance of the publication is due to the scientific interest in the sphere of interaction of citizens with the environment and comfortable urban environment formation. The purpose of the paper is to analyze the subjective opinion of residents about urban planning problems and the conditions of optimal living environment formation. Based on the results of the polls the main negative factors of the urban environment were identified, in particular, poor ecology, lack of landscaping. Preferred and undesirable areas of the city for living have been named. Based on the respondents' answers, a “social order” was formed to optimize the urban environment and solve urban planning problems. The authors suggest that involving the citizens in solving urban problems increases their social responsibility for creating a comfortable living environment. The empirical research allows us to think that in order to create a favorable urban environment, urban planning consciousness and culture with a human dimension must appear among townspeople. In this article according to sociological surveys, we have broadly subjectively revealed and assessed the quality of life of respondents in the non-production fixed assets of social consumption in Tambov.

Residual transmission is the persistence of malaria transmission after scale-up of appropriate vector control tools and is one of the key challenges for malaria elimination today. Although long associated with outdoor biting, other mosquito behaviours such as partly feeding upon animals contribute greatly to sustaining transmission. Peri-domestic livestock can be used as decoy to protect humans from blood-seeking vectors but this approach often leads to an increased malaria risk in a phenomenon known as zoopotentiation. Treating the said livestock with drugs capable of killing intestinal parasites as well as mosquitoes that feed upon them has the potential to tackle malaria through a previously unexplored mechanism. The advantages and challenges associated with this approach are briefly discussed here. Numerous references are purposely provided. This article is part of the theme issue ‘Novel control strategies for mosquito-borne diseases’.

Background: Heterogeneity in malaria transmission has household, temporal, and spatial components. These factors are relevant for improving the efficiency of malaria control by targeting heterogeneity. To quantify variation, we analyzed mosquito counts from entomological surveillance conducted at three study sites in Uganda that varied in malaria transmission intensity. Methods: Using a Bayesian zero-inflated negative binomial model, validated via a comprehensive simulation study, we quantified household differences in malaria vector density and examined its spatial distribution. We introduced a novel approach for identifying changes in malaria hotspots over time by computing the Getis-Ord statistic on ratios of household biting propensities for different scenarios. We also explored the association of household biting propensities with housing and environmental covariates. Results: In each site, there was evidence for hot and cold spots, spatial patterns associated with urbanicity, elevation, or other environmental covariates. We found some differences in the hotspots in rainy vs. dry seasons or before vs. after the application of control interventions. Housing quality explained a portion of the variation among households in mosquito counts. Conclusion: This work provided an improved understanding of heterogeneity in malaria vector density at the three study sites in Uganda and offered a valuable opportunity for assessing whether interventions could be spatially targeted to be aimed at hotspots of malaria risk. Indoor residual spraying was shown to be a successful measure of vector control interventions in Tororo, Uganda.  Cement walls, brick floors, closed eaves, screened airbricks, and tiled roofs were features of a house that had shown protective effects towards malaria risk. Improvements in house quality should be recommended as a supplementary measure for malaria control.

The quality of bearing production has an impact not only on their reliability and lifetime, but also on the dynamic load of the working and living environment by excessive vibration and thus also noise. The intensity of the noise emitted by a bearing which is perceived by man characterizes the quality of its production. Reducing the dynamic load of mechanical systems and their components is reflected in the working environment by reducing noise emissions and immissions. The article proposes an objective method of bearing quality assessment based on measuring vibro-acoustic parameters of dynamic load of a new bearing using FFT analysis and the magnitude of the amplitude of bearing vibration acceleration and compares it with a subjective method that also uses the human auditory organ to assess bearing quality. The results of vibro-acoustic measurements were analysed in terms of vibration intensity and the noise of the produced bearings. The proposed objective methodology was compared with the subjective evaluation of the quality of bearings and the results of this methodology matched. The proposed methodology is applicable to all types of bearings, and it is possible to automate this methodology in the production process.

The Social

Background: The analysis has involved social interactions in a multicultural environment. The social context has been defined by the Vilnius region (Lithuania), where national, religious, and cultural differences exist across generations (multicultural community). The space of “social relationships”, as one of the modules of the WHO quality of life assessment, has been studied. An innovation of the research has been related to the analysis of the phenomenon of community of nationalities and cultures as a predictor of quality of life (QoL). The social motive of the research has been the historical continuity (for centuries) of the construction of the Vilnius cultural borderland. Here, the local community evolves from a group of many cultures to an intercultural community. Interpreting the data, therefore, requires a long perspective (a few generations) to understand the quality of relationships. We see social interactions and strategies for building them as a potential for social QoL in multicultural environments. Methods: The research has been conducted on a sample of 374 respondents, including Poles (172), Lithuanians (133), and Russians (69). A diagnostic poll has been used. The respondents were adolescents (15–16 years). The research answers the question: What variables form the interaction strategies of adolescents in a multicultural environment? The findings relate to interpreting the social interactions of adolescents within the boundaries of their living environment. The description of the social relations of adolescents provides an opportunity to implement the findings for further research on QoL. Results: An innovative outcome of the research is the analysis of 3 interaction strategies (attachment to national identification, intercultural dialogue, and multicultural community building) as a background for interpreting QoL in a multicultural environment. Their understanding is a useful knowledge for QoL researchers. The data analysis has taken into account cultural and generational (historical) sensitivities. Therefore, the team studying the data has consisted of researchers and residents of the Vilnius region. We used the interaction strategies of adolescents to describe the category of “social relationships” in nationally and culturally diverse settings.

AbstractOlder people today are more likely to age in their own private living environment. However, many face declining health and/or other issues that affect their ability to live independently and necessitate additional support. Such support can be provided by formal networks, but a considerable part can also be offered by informal networks of older people themselves. Going beyond these networks, older people can additionally and perhaps even more substantially benefit from vital communities. Nevertheless, even though this term is increasingly common in the literature, its meaning remains indistinct. A more thorough understanding of this concept might provide valuable knowledge that health care professionals, researchers and community workers can use to offer meaningful and effective support. The purpose of this paper is to draw on existing empirical research on vital communities to build knowledge of the different descriptions and dimensions of the concept. Arksey and O’Malley’s scoping review methodology was adopted. Our search, conducted on 23 March 2020 and updated on 06 January 2021, yielded 4433 articles, of which six articles were included in the scoping review. We deduced that the conceptualisation of a vital community is based on three dimensions: the aim of a vital community, the processes behind a vital community and the typical characteristics of a vital community. None of the selected studies have mapped all three dimensions. Nevertheless, we assume that understanding all three matters when vital communities aim to contribute to the quality of life of people ageing in place.

Urban Settlements

The migration of human populations from rural to urban settlements known as urbanization in its most basic sense suggests an improvement in various facets of life. Urbanization ideally should also imply an enhancement of housing quality and other components of human settlements such as power supply, portable water, good roads, proper refuse and sewage disposal facilities, maintenance of ecological balance and a reduction in environmental pollution. Globally, the urbanization process has occurred in a disorganized and nearly uncontrollable manner. The spontaneity in growth of urban settlements has affected negatively several components of the urban fabric such that these components (previously mentioned) are either severely inadequate or non-existent in majority of instances where urbanization has taken place. Arguably, the success of any urbanization process can be measured by the quality of the environments produced and the housing stock found within such environments. This paper seeks to identify and evaluate the components of urban settlements that can be used as indices for establishing quality of our housing, environments and urban clusters particularly for the Nigerian context. The research methodology is a reconnaissance survey, field observation and comparison of four main areas within Ido Local Government Area of Ibadan, Oyo State, namely Apete, Elebu, Elenusonso and Ologuneru.Key words: Urbanization, Environmental quality indicators.
