World Rabies Day - a decade of raising awareness
World Rabies Day was set up in 2007 to raise global awareness about rabies, to provide information on how to prevent the disease in at-risk communities and support advocacy for increased efforts in rabies control. It is held annually on September 28th, with events, media outreach and other initiatives carried out by individuals, professionals, organisations and governments from the local to the international level. The Global Alliance for Rabies Control coordinates World Rabies Day, amplifying the campaign's reach through the provision of a central event platform and resources to support events across the world, the promotion of messages through key rabies stakeholders, and the implementation of specific activities to highlight particular issues. Over the last decade, more than 1,700 registered events have been held across the world and shared with others in the global rabies community. Events in canine rabies endemic countries, particularly in Africa and Asia, have increased over time. Beyond the individual events, World Rabies Day has gained the support of governments and international agencies that recognise its value in supporting existing rabies control initiatives and advocating for improvements. As the rabies landscape has changed, World Rabies Day remains a general day of awareness but has also become an integral part of national, regional and global rabies elimination strategies. The global adoption of 2030 as the goal for the elimination of rabies as a public health threat has led to even greater opportunities for World Rabies Day to make a sustainable impact on rabies, by bringing the attention of policy makers and donors to the ongoing situation and elimination efforts in rabies-endemic countries
Difficulties in estimating the human burden of canine rabies
Current passive surveillance data for canine rabies, particularly for the regions where the burden is highest, are inadequate for appropriate decision making on control efforts. Poor enforcement of existing legislation and poor implementation of international guidance reduce the effectiveness of surveillance systems, but another set of problems relates to the fact that canine rabies is an untreatable condition which affects very poor sectors of society. This results in an unknown, but potentially large proportion of rabies victims dying outside the health system, deaths that are unlikely to be recorded by surveillance systems based on health center records. This article critically evaluates the potential sources of information on the number of human deaths attributable to canine rabies, and how we might improve the estimates required to move towards the goal of global canine rabies elimination
Learnerships and employability: A Case Study of a private provider's delivery of a learnership in the Information Technology sector.
Magister Philosophiae - MPhilIn this research paper, I explore the relationship between learnerships and employability.
Will I get a job after completing a learnership? This question is posed by many if not
most learners participating in learnerships. Learnerships have been promoted as
improving the skills level of the population as integral part of economic growth in South
Africa. This is still in process as the impact of completed learnerships still has to be felt
and seen in industry, especially in increased employment or improving the possibility of
employment. In this paper I investigate the relationship between a learnership and
employment
Managers’ less favourable attitude towards bottom of the pyramid (BOP) customers
Investment in low income markets is increasing so too is a sense of controversy regarding poor markets. With BOP investment becoming many a firms’ strategy towards achieving growth, it is not clear to what extent managers’ attitudes to poor customers differ towards their attitudes towards middle-class customers. It is, however, well described that attitudes to poor people in a social context is negative and in some cases less favourable. It is postulated that business' mindset may be a barrier towards engaging with BOP markets despite the incentives and benefits that literature puts forward for marketing to the poor. Whether this attitude is negative, neutral, less favourable or similar is not well understood. The findings of this research project, can with a high level of confidence, report that the attitudes of a sample of managers do display a less favourable attitude towards a poor customer than is the case with a similar sample that is exposed to a wealthier customer.Dissertation (MBA)--University of Pretoria, 2012.Gordon Institute of Business Science (GIBS)unrestricte
A Bayesian approach for inferring the dynamics of partially observed endemic infectious diseases from space-time-genetic data
We describe a statistical framework for reconstructing the sequence of transmission events between observed cases of an endemic infectious disease using genetic, temporal and spatial information. Previous approaches to reconstructing transmission trees have assumed all infections in the study area originated from a single introduction and that a large fraction of cases were observed. There are as yet no approaches appropriate for endemic situations in which a disease is already well established in a host population and in which there may be multiple origins of infection, or that can enumerate unobserved infections missing from the sample. Our proposed framework addresses these shortcomings, enabling reconstruction of partially observed transmission trees and estimating the number of cases missing from the sample. Analyses of simulated datasets show the method to be accurate in identifying direct transmissions, while introductions and transmissions via one or more unsampled intermediate cases could be identified at high to moderate levels of case detection. When applied to partial genome sequences of rabies virus sampled from an endemic region of South Africa, our method reveals several distinct transmission cycles with little contact between them, and direct transmission over long distances suggesting significant anthropogenic influence in the movement of infected dogs
Die rol van nostalgie binne die konsep van ontluistering in die werk van N.P. van Wyk Louw
Bibliography: pages 166-172.The reason for this study was to determine if there is any connection between nostalgia and the debunking effect in the work of N.P. van Wyk Louw Starting with a thorough explanation of the term nostalgia to establish any implications the word might have. They can be summarised as: A longing for a simple life without loneliness where the person will feel at home. A desire to reach a better understanding of God and the primordial as the source of all life. Nostalgia develops as a result of a interrelationship between the past, present and the future and an interrelationship between the abstract and concrete aspects of nostalgia. In short: Nostalgia is a desire to establish an Utopian existence. It was found that the secondary literature on the topic is of a limited nature. The literature relating to Van Wyk Louw concentrates mostly on Nuwe Verse and Tristia and especially on the type of language used in "Klipwerk" and the fact that the author resided in the Netherlands while writing these two books. To outline the developement of nostalgic tendencies, the theme-poem of every book was looked at and it was found that Alleenspraak, Die Halwe Kring and Gestaltes en Diere encompasses the desire aspect of nostalgia, while Nuwe Verse and Tristia have a bearing on the remembrance aspect. The study of the love-, monologue- and prophet-figures showed that the search for certainty and unity leads has a debunking effect. Innocence brings the primordial into play which was studied using the poem "Die Swart Luiperd". The study showed that it is impossible to return to origin of life. With the debunking of the abstract aspects of nostalgia, attention was given to the earthly aspects. In this regard it was also found that the human being is isolated. Lastly, the poem "Groot Ode" was looked at to see if the poet has any answer to the debunking effect of nostalgia. Here irony was suggested as an answer to the debunking effect of nostalgia and as something that would make nostalgia bearable
The Role of Dog Population Management in Rabies Elimination—A Review of Current Approaches and Future Opportunities
Free-roaming dogs and rabies transmission are integrally linked across many low income countries, and large unmanaged dog populations can be daunting to rabies control program planners. Dog population management (DPM) is a multifaceted concept that aims to improve the health and well-being of free-roaming dogs, reduce problems they may cause, and may also aim to reduce dog population size. In theory, DPM can facilitate more effective rabies control. Community engagement focused on promoting responsible dog ownership and better veterinary care could improve the health of individual animals and dog vaccination coverage, thus reducing rabies transmission. Humane DPM tools, such as sterilization, could theoretically reduce dog population turnover and size, allowing rabies vaccination coverage to be maintained more easily. However, it is important to understand local dog populations and community attitudes toward them in order to determine whether and how DPM might contribute to rabies control and which DPM tools would be most successful. In practice, there is very limited evidence of DPM tools achieving reductions in the size or turnover of dog populations in canine rabies-endemic areas. Different DPM tools are frequently used together and combined with rabies vaccinations, but full impact assessments of DPM programs are not usually available, and therefore, evaluation of tools is difficult. Surgical sterilization is the most frequently documented tool and has successfully reduced dog population size and turnover in a few low-income settings. However, DPM programs are mostly conducted in urban settings and are usually not government funded, raising concerns about their applicability in rural settings and sustainability over time. Technical demands, costs, and the time necessary to achieve population-level impacts are major barriers. Given their potential value, we urgently need more evidence of the effectiveness of DPM tools in the context of canine rabies control. Cheaper, less labor-intensive tools for dog sterilization will be extremely valuable in realizing the potential benefits of reduced population turnover and size. No one DPM tool will fit all situations, but if DPM objectives are achieved dog populations may be stabilized or even reduced, facilitating higher dog vaccination coverages that will benefit rabies elimination efforts
Dog bite histories and response to incidents in canine rabies-enzootic KwaZulu-Natal, South Africa
The objective of this paper is to report evaluated observations from survey records captured through a cross-sectional
observational study regarding canine populations and dog owners in rabies enzootic KwaZulu-Natal province, South Africa.
Our aim was to evaluate respondent knowledge of canine rabies and response to dog bite incidents towards improved
rabies control. Six communities consisting of three land use types were randomly sampled from September 2009 to January
2011, using a cluster design. A total of 1992 household records were analyzed using descriptive statistics and regression
modeling to evaluate source of rabies knowledge, experiences with dog bites, and factors affecting treatment received
within respective households that occurred within the 365 day period prior to the surveys. 86% of the population surveyed
had heard of rabies. Non-dog owners were 1.6 times more likely to have heard of rabies than dog owners; however, fear of
rabies was not a reason for not owning a dog. Government veterinary services were reported most frequently as respondent
source of rabies knowledge. Nearly 13% of households had a member bitten by a dog within the year prior to the surveys
with 82% of the victims visiting a clinic as a response to the bite. 35% of these clinic visitors received at least one rabies
vaccination. Regression modeling determined that the only response variable that significantly reflected the likelihood of a
patient receiving rabies vaccination or not was the term for the area surveyed. Overall the survey showed that most
respondents have heard of dog associated rabies and seek medical assistance at a clinic in response to a dog bite regardless
of offending dog identification. An in-depth study involving factors associated within area clinics may highlight the area
dependency for patients receiving rabies post exposure prophylaxis shown by this model.Humane Society International provided $10,000 in 2009 for Dr. Melinda Hergert to condcut this research (www.hsi.org). Bill and Melinda Gates
Foundation did not contribute directly to this research but rather indirectly by the researcher piggy-backing onto an existing project (www.gatesfoundation.org).http://www.plosntds.orgam2013mn201
Lyssaviruses and the fatal encephalitic disease rabies
Lyssaviruses cause the disease rabies, which is a fatal encephalitic disease resulting in
approximately 59,000 human deaths annually. The prototype species, rabies lyssavirus, is
the most prevalent of all lyssaviruses and poses the greatest public health threat. In Africa,
six confirmed and one putative species of lyssavirus have been identified. Rabies
lyssavirus remains endemic throughout mainland Africa, where the domestic dog is the
primary reservoir – resulting in the highest per capita death rate from rabies globally.
Rabies is typically transmitted through the injection of virus-laden saliva through a bite or
scratch from an infected animal. Due to the inhibition of specific immune responses by
multifunctional viral proteins, the virus usually replicates at low levels in the muscle tissue
and subsequently enters the peripheral nervous system at the neuromuscular junction.
Pathogenic rabies lyssavirus strains inhibit innate immune signaling and induce cellular
apoptosis as the virus progresses to the central nervous system and brain using viral
protein facilitated retrograde axonal transport. Rabies manifests in two different forms - the
encephalitic and the paralytic form - with differing clinical manifestations and survival times.
Disease symptoms are thought to be due mitochondrial dysfunction, rather than neuronal
apoptosis. While much is known about rabies, there remain many gaps in knowledge
about the neuropathology of the disease. It should be emphasized however, that rabies is
vaccine preventable and dog-mediated human rabies has been eliminated in various
countries. The global elimination of dog-mediated human rabies in the foreseeable future
is therefore an entirely feasible goal.http://www.frontiersin.org/Immunologyam2022BiochemistryGeneticsMicrobiology and Plant Patholog
Molecular phylogeny of Duvenhage virus
The Duvenhage virus (DUVV) constitutes one of the 11 species in the Lyssavirus genus and
causes fatal rabies encephalitis. The virus is associated with insectivorous bat species and three
human cases have been reported, all of which were linked to contact with bats. Few of these
isolates have been studied and thus little is known about the phylogeny and epidemiology of
this lyssavirus. Until 2007, when an isolate was made from the East African country of Kenya,
all isolations of this virus had been from southern Africa. This discovery led to many questions
regarding the spread and diversity of this lyssavirus. Phylogenetic analysis indicated that the
DUVV isolates constitute two different lineages, in which the southern African isolates group
together to form one lineage and the more recent isolate from Kenya constitutes a new, second
lineage. We found that the new isolate has a genetic variation that has not yet been seen for
DUVV. Not only is our lack of knowledge regarding the geographical distribution of this
uniquely African virus emphasised, but we have also demonstrated the potential diversity
within this genotype.http://www.sajs.co.z
