Author(s):  
RL van Zyl

Sub-Saharan Africa has to contend with many challenges, including inadequate healthcare systems, lack of optimal sanitation, and clean water and food. All of these contribute to malnutrition and an increased risk of infections, including parasitism by cestodes and trematodes. Schistosomiasis is a category-2 notifiable trematode (fluke) infection, whereas cestode (tapeworm) infections need not be reported to the South African Department of Health. Epidemiological data for helminthiasis in South Africa is scant, with a paucity of publications on the South African scenario. As such, a complete picture of the impact of helminth infections on all age groups in South Africa does not exist. These parasitic diseases not only have an impact on socio economic development of a country, community and families, but also contribute to the chronic and detrimental effects on the health and nutritional status of the host, including the impaired development of children. In order to break the cycle of poverty and disease, a strong education drive is required in schools and communities to provide effective strategies and guidelines on preventative measures that result in avoidance of exposure to infective stages of Schistosoma and Taenia tapeworms. Also, it is imperative that healthcare professionals are able to recognise the signs and symptoms, so that interventions can be promptly initiated. The current anthelmintic treatments available in South Africa are effective against cestodes and trematodes, with no drug resistance having being reported. The need for compliancy when taking anthelmintic drugs must be emphasised.

Professional  journals  are  used  to  disseminate  the  knowledge of scholars in the profession and to provide clinicians with guidance for best practice.  This  article  aimed  to  retrospectively  review  the  role  of the  South African  Journal  of  Physiotherapy  and  its  contribution  to  the profession.  An archival  research  design  was  used  to  collect  information from  the  archives of  the  South  African  Society  of  Physiotherapy website.  The  information  was retrieved  using  a  data  capture  sheet and descriptive  statistics  were  used throughout  to  establish  frequencies  for the  relevant  information.  During  the identified period, 170 articles were published. The greatest number of papers originated in South Africa (81%), 8% from the rest of Africa and 11% written by international authors. Authors with a Masters degree contributed almost 50% of the papers and those with doctorates were responsible for at least 25% of the papers. Most of the papers presented original research (81%) with secondary research such as reviews and scholarly papers accounting for 19% of the total. The most common speciality area addressed through research  was  linked  to musculoskeletal  conditions.  The  journal  appears  to  have  provided  an important  platform  for  South African academics and emerging researchers to publish their findings. It is suggested that the journal should give preference to papers that deal with issues that are unique to South Africa and sub-Saharan Africa, as these are the least likely to be published elsewhere. In addition, the journal should emphasise papers that will advance the profession.

Background: ST-elevation myocardial infarction (STEMI) is on the rise in sub-Saharan Africa. South Africa consistently fails to deliver timely reperfusion to these patients, possibly due to under-developed coronary care networks (CCN). Objectives: To determine the current perceived state of CCNs, to determine the barriers to optimising CCNs and to suggest facilitators to optimising CCNs within the South African context. Methods: A qualitative descriptive approach was employed, by performing two structured in-depth and two focus group inter- views (n=4 and 5, respectively), inviting a purposely heterogeneous sample of 11 paramedics (n=4), doctors (n=5), and nurses (n=2) working within different settings in South African CCNs. Recorded interviews were transcribed verbatim and subjected to content analysis. Results: Participants described an under-resourced, unprioritised and fragmented CCN with significant variation in perfor- mance. Barriers to CCN optimisation resided in recognition and diagnosis of STEMI, transport and treatment decisions, and delays. Participants suggested that thrombolysing all STEMI patients could facilitate earlier reperfusion and that pre-hospital thrombolysis should be considered. Participants highlighted the need for regionalised STEMI guidelines, and the need for fur- ther research. Conclusion: Numerous barriers were highlighted. Healthcare policy-makers should prioritise the development of CCNs that is underpinned by evidence and that is contextualised to each specific region within the South African health care system. Keywords: Health care system; emergency care; cardiovascular disease.

BACKGROUND The impact of climate temperature on the counts (number of positive COVID-19 cases reported), recovery, and death rates of COVID-19 cases in South Africa's nine provinces was investigated. The data for confirmed cases of COVID-19 were collected for March 25 and June 30, 2020 (14 weeks) from South Africa's Government COVID-19 online resource, while the daily provincial climate temperatures were collected from the website of the South African Weather Service. Our result indicates that a higher or lower climate temperature does not prevent or delay the spread and death rates but shows significant positive impacts on the recovery rates of COVID-19 patients. Thus, it indicates that the climate temperature is unlikely to impose a strict limit on the spread of COVID-19. There is no correlation between the cases and death rates, an indicator that no particular temperature range is closely associated with a faster or slower death rate of COVID-19 patients. As evidence from our study, a warm climate temperature can only increase the recovery rate of COVID-19 patients, ultimately impacting the death and active case rates and freeing up resources quicker to enable health facilities to deal with those patients' climbing rates who need treatment. OBJECTIVE This study aims to investigate the impact of climate temperature variation on the counts, recovery, and death rates of COVID-19 cases in all South Africa's provinces. The findings were compared with those of countries with comparable climate temperature values. METHODS The data for confirmed cases of COVID-19 were collected for March 25 and June 30 (14 weeks) for South African provinces, including daily counts, death, and recovery rates. The dates were grouped into two, wherein weeks 1-5 represent the periods of total lockdown to contain the spread of COVID-19 in South Africa. Weeks 6-14 are periods where the lockdown was eased to various levels 4 and 3. The daily information of COVID-19 count, death, and recovery was obtained from South Africa's Government COVID-19 online resource (https://sacoronavirus.co.za). Daily provincial climate temperatures were collected from the website of the South African Weather Service (https://www.weathersa.co.za). The provinces of South Africa are Eastern Cape, Western Cape, Northern Cape, Limpopo, Northwest, Mpumalanga, Free State, KwaZulu-Natal, Western Cape, and Gauteng. Weekly consideration was given to the daily climate temperature (average minimum and maximum). The recorded values were considered, respectively, to be in the ratio of death-to-count (D/C) and recovery-to-count (R/C). Descriptive statistics were performed for all the data collected for this study. The analyses were performed using the Person’s bivariate correlation to analyze the association between climate temperature, death-to-count, and recovery-to-count ratios of COVID-19. RESULTS The results showed that higher climate temperatures aren't essential to avoid the COVID-19 from being spread. The present results conform to the reports that suggested that COVID-19 is unlike the seasonal flu, which does dissipate as the climate temperature rises [17]. Accordingly, the ratio of counts and death-to-count cannot be concluded to be influenced by variations in the climate temperatures within the study areas. CONCLUSIONS The study investigates the impact of climate temperature on the counts, recovery, and death rates of COVID-19 cases in all South Africa's provinces. The findings were compared with those of countries with comparable climate temperatures as South Africa. Our result indicates that a higher or lower climate temperature does not prevent or delay the spread and death rates but shows significant positive impacts on the recovery rates of COVID-19 patients. Warm climate temperatures seem not to restrict the spread of the COVID-19 as the count rate was substantial at every climate temperatures. Thus, it indicates that the climate temperature is unlikely to impose a strict limit on the spread of COVID-19. There is no correlation between the cases and death rates, an indicator that there is no particular temperature range of the climatic conditions closely associated with a faster or slower death rate of COVID-19 patients. However, other shortcomings in this study's process should not be ignored. Some other factors may have contributed to recovery rates, such as the South African government's timely intervention to announce a national lockout at the early stage of the outbreak, the availability of intensive medical care, and social distancing effects. Nevertheless, this study shows that a warm climate temperature can only help COVID-19 patients recover more quickly, thereby having huge impacts on the death and active case rates.

IntroductionCardiovascular disease (CVD) risk factors are increasing in sub-Saharan Africa. The impact of these risk factors on future CVD outcomes and burden is poorly understood. We examined the magnitude of modifiable risk factors, estimated future CVD risk and compared results between three commonly used 10-year CVD risk factor algorithms and their variants in four African countries.MethodsIn the Africa-Wits-INDEPTH partnership for Genomic studies (the AWI-Gen Study), 10 349 randomly sampled individuals aged 40–60 years from six sites participated in a survey, with blood pressure, blood glucose and lipid levels measured. Using these data, 10-year CVD risk estimates using Framingham, Globorisk and WHO-CVD and their office-based variants were generated. Differences in future CVD risk and results by algorithm are described using kappa and coefficients to examine agreement and correlations, respectively.ResultsThe 10-year CVD risk across all participants in all sites varied from 2.6% (95% CI: 1.6% to 4.1%) using the WHO-CVD lab algorithm to 6.5% (95% CI: 3.7% to 11.4%) using the Framingham office algorithm, with substantial differences in risk between sites. The highest risk was in South African settings (in urban Soweto: 8.9% (IQR: 5.3–15.3)). Agreement between algorithms was low to moderate (kappa from 0.03 to 0.55) and correlations ranged between 0.28 and 0.70. Depending on the algorithm used, those at high risk (defined as risk of 10-year CVD event >20%) who were under treatment for a modifiable risk factor ranged from 19.2% to 33.9%, with substantial variation by both sex and site.ConclusionThe African sites in this study are at different stages of an ongoing epidemiological transition as evidenced by both risk factor levels and estimated 10-year CVD risk. There is low correlation and disparate levels of population risk, predicted by different risk algorithms, within sites. Validating existing risk algorithms or designing context-specific 10-year CVD risk algorithms is essential for accurately defining population risk and targeting national policies and individual CVD treatment on the African continent.

The purpose of this paper is to examine two South Africa legislations dealing with over indebtedness of a consumer. It is clear that in terms of the South African law, section 129 (1) and 130 (3) of the National Credit Act provide that a creditor provider who wishes to enforce a debt under a credit agreement must first issue a section 129 (1) (a) notice to the consumer (the purpose of the notice is to notify the consumer of his/her arrears). On the other hand, the South African National Credit Act encourages the consumers to fulfil the financial obligations for which they are responsible. The second legislation to be examined which serve or appear to serve same purpose as the National Credit Act is the Insolvency Act. It therefore, postulated that the compulsory sequestration of a consumer in terms of the Insolvency Act would stand as an alternative remedy for a credit provider before she/he can have recourse mechanisms, such as debt review that are focused on satisfaction of the consumer’s financial obligation , in terms of the provisions of the National Credit Act. The paper determines to what extend these measures comply with the constitutional consumer protection demands. The legislature had been pertinently cognizant of the Insolvency Act when it lately enacted the National Credit Act. This is much apparent from the express amendment of section 84 of the Insolvency Act to the extent set out in schedule 2 of the National Credit Act

Prior to the introduction of highly resistant sugarcane varieties, Sugarcane streak virus (SSV) caused serious sugar yield losses in southern Africa. Recently, sugarcane plants with streak symptoms have been identified across South Africa. Unlike the characteristic fine stippling and streaking of SSV, the symptoms resembled the broader, elongated chlorotic lesions commonly observed in wild grasses infected with the related Maize streak virus (MSV). Importantly, these symptoms have been reported on a newly released South African sugarcane cultivar, N44 (resistant to SSV). Following a first report from southern KwaZulu-Natal, South Africa in February 2006, a survey in May 2007 identified numerous plants with identical symptoms in fields of cvs. N44, N27, and N36 across the entire South African sugarcane-growing region. Between 0.04 and 1.6% of the plants in infected fields had streak symptoms. Wild grass species with similar streaking symptoms were observed adjacent to one of these fields. Potted stalks collected from infected N44 plants germinated in a glasshouse exhibited streak symptoms within 10 days. Virus genomes were isolated and sequenced from a symptomatic N44 and Urochloa plantaginea plants collected from one of the surveyed fields (1). Phylogenetic analysis determined that while viruses from both plants closely resembled the South African maize-adapted MSV strain, MSV-A4 (>98.5% genome-wide sequence identity), they were only very distantly related to SSV (~65% identity; MSV-Sasri_S: EU152254; MSV-Sasri_G: EU152255). To our knowledge, this is the first confirmed report of maize-adapted MSV variants in sugarcane. In the 1980s, “MSV strains” were serologically identified in sugarcane plants exhibiting streak symptoms in Reunion and Mauritius, but these were not genetically characterized (2,3). There have been no subsequent reports on the impact of such MSV infections on sugarcane cultivation on these islands. Also, at least five MSV strains have now been described, only one of which, MSV-A, causes significant disease in maize and it is unknown which strain was responsible for sugarcane diseases on these islands in the 1980s (2,3). MSV-A infections could have serious implications for the South African sugar industry. Besides yield losses in infected plants due to stunting and reduced photosynthesis, the virus could be considerably more difficult to control than it is in maize because sugarcane is vegetatively propagated and individual plants remain within fields for years rather than months. Moreover, there is a large MSV-A reservoir in maize and other grasses everywhere sugarcane is grown in southern Africa. References: (1) B. E. Owor et al. J Virol. Methods 140:100, 2007. (2) M. S.

This chapter explores South African competition law. South Africa has the most sophisticated system of competition law and policy in sub-Saharan Africa. It has a mission to expand economic opportunity and facilitate inclusive development. In the wake of the UN Millennium Development Goals and the follow-on Sustainable Development Goals, there is a new world consciousness of the need to combat deep systemic poverty and to reverse the tide of increasing inequality of wealth, income, and opportunity. If there is any nation in the world whose competition law mandates integration of equity and efficiency, it is South Africa, and its policymakers are intent to address this need. The chapter looks at the South African Competition Act and highlights selected cases to illustrate the law and its implementation, including the effort by the Competition Tribunal to give serious regard to the equality and inclusiveness values that animated the statute.

Depression is a common psychiatric disorder and can be costly, having a significant impact on the individual and employers. The South African Depression and Anxiety Group (SADAG) in partnership with HEXOR, with the support of Lundbeck, undertook research into depression in the workplace, because South African information is not available on this topic. It provides insight into the prevalence of depression within the workplace in South Africa, as well as the impact of depression on the employees and employers in terms of sick leave and levels of productivity, especially when the symptoms include cognitive impairment. It is apparent that stigma plays a pivotal role in the reasons for non-disclosure to employers. It further highlights the magnitude of awareness, early detection and the provision of a holistic support system within the work environment, free from bias, to ensure that optimum benefit can be achieved for both employer and employee.

Background: Regional trade could be a powerful engine of economic growth and sustainable job creation. However, South Africa’s exports to sub-Saharan Africa (SSA) are typically smaller and more short-lived than its exports to its traditional markets. This is despite South African policymakers considering trade with SSA to be a priority. Aim: The aim of the article is to evaluate South Africa’s utilisation of sustained export potential in SSA with a view to providing practical insights that will inform future policymaking and planning. Setting: Despite the priority attention given to SSA in the country’s trade policy, South Africa is yet to make meaningful inroads into SSA’s largest and fastest-growing economies. Method: The research method applied comprised three steps. The first step involved the identification, over a five-year period from 2010 to 2014, of consistently large and/or growing import demand in SSA for all products at the Harmonised System (HS) six-digit level, as well as the identification of products South Africa consistently exported competitively (sustainable exports). The second step entailed matching SSA markets with consistently large and/or growing import demand to South Africa’s sustainable exports. The third step involved evaluating South Africa’s utilisation of sustained export potential in SSA. Results: The results reveal that South Africa is utilising just over half (54%) of its sustained export potential in SSA. Conclusion: South Africa is, therefore, underutilising or not utilising close to 50% of its sustained export potential in SSA. Most of the export potential that South Africa is utilising is in Eastern Africa while most of the export potential that the country is underutilising and not utilising at all is in Central and Western Africa.

Many developing countries are facing high levels of unemployment and most people who are employed are poorly remunerated due to low skills and productivity levels. Although jobs are important, a productive job is even more important, not only for employees, but also for employers. South Africa, being a developing country, is also facing the challenge of dramatically high levels of unemployment. This study’s aim was to examine both the short- and long-term impacts of real wages, labour productivity and investment spending on employment absorption rates in South Africa. To establish the existing relationship between variables, the study applied several econometric approaches, such as an autoregressive distributed lag (ARDL) model, error correction model (ECM) and a Toda–Yamamoto causality analysis on quarterly time series data from 1995Q1 to 2019Q1. The results revealed the existence of both short- and long-run relationships among the variables. While a positive relationship was found between employment absorption, investment spending and labour productivity, it was found that real wages negatively impact on long-run employment absorption rates. Additionally, the short-run analysis indicated that the lagged employment absorption rate influences the current rate of employment. Furthermore, the causality tests indicated that a bi-directional causal relationship exists between employment absorption and investment spending; and a uni-directional relationship between employment and both real wages and labour productivity. Based on the findings, the study recommends increments of investment spending and labour productivity that enables the South African economy to carry out more activities that would require more workers, thereby improving the employment absorption rate. The fact that labour productivity positively impacts the employment absorption rate infers the requirement for quality and skilled workers to be absorbed in the South African labour market. Therefore, labour skills improvements appear to be a prerequisite for productivity enhancement and job creation.
