- Description: Background and Aim Contact tracing is a critical public health measure for controlling and preventing the spread of infectious diseases. Although the principles underlying this strategy are not novel, understanding the changes in infectiousness of COVID-19 is indeed novel. As are the capacity and operating procedures required to support disease investigation in Mangang Metro during the SARS-CoV-2 (COVID-19) pandemic. On 16 March 2020, the first coronavirus disease case in the area, which led to a larger outbreak, occurred in Mangaung Metro, Free State province, South Africa. To date, Mangaung Metro remains the epicentre of the COVID-19 pandemic and the primary driver of the caseload in the Free State province. The aim of this study was to analyse contact tracing data in Mangaung Metro during the early phase of the COVID-19 outbreak (16 March 2020 – 30 June 2020) in order to measure the viral transmissibility of COVID-19 in the early stages of the outbreak, specifically in the context of Mangaung Metro. Methods A descriptive systematic analysis of index COVID-19 cases and their contacts in Mangaung Metro was conducted. The review period ran from 16 March to 30 June 2020, during which there was a total of 1 001 cases in Mangaung Metro. Data was captured on an Excel spreadsheet using the contact line list variables from the established National Institute of Communicable Disease contact line list framework. The inferential statistics were based on a time series analysis to compare the impact of contact tracing stratified by symptomatology and the root cause of the cases to the overall cases in Mangaung Metro. The study determined whether isolation, quarantine, and contact tracing were able to control outbreaks in the early phase using characteristics of disease transmission and parameters particularised to the COVID- 19 pathogen. Results As of 30 June 2020, the Free State province had a total of 2 072 COVID-19 cases. Mangaung Metro contributed 1 001 cases (48percent) of the total number of cases in the study period. Between March and June 2020, 3 553 contacts were traced in Mangaung Metro. This number translates to at least three investigated and traced contacts per index or laboratory confirmed positive case. From the traced contacts, 1 080 samples were collected and sent for laboratory testing. In April 2020, the greatest number of samples were collected. This high rate in sample collection is posited to be the result of the high rate of contacts traced, as well as the initial clinical guidelines followed for contact tracing. Most positive contacts were discovered in March 2020. One of the possible reasons for the high detection of COVID-19 confirmed positive contacts during the early stages of the outbreak was the focus and importance of contact tracing while the caseload remained relatively low. However, as the outbreak progressed in the Mangaung Metro context, the number and relative percentage of positive cases detected through contact tracing decreased. In total, the positive contacts recorded in March 2020 amounted to 92 (51.3percent), 18 in April (10.5percent), 41 in May (22.9percent), and 28 in June (15.6percent). The March 2020 tracking rate was the highest at 73.2percent, with an average contact tracing rate of 15.5percentby the end of June 2020. Of all the contacts traced, 7.9percent involved healthcare workers in the Free State. Conclusion The study’s findings show that contact tracing was an effective control measure during the early stages of the COVID-19 outbreak in Mangung Metro district. Furthermore, the impact was greatest when the caseload was low and the burden on the healthcare system less severe. Mangaung Metro demonstrated the capability of tracing more contacts in the early-early phase of the outbreak; however, as the outbreak progressed to the latent early phase, the caseload increased and fewer contacts were traced. The consequence of contact tracing not being as effective during the latent early phase relates to the increase in both exposed and untraceable contacts, which in turn fueled the increase of new cases. This further impacted the at-risk and vulnerable population, especially the elderly, who were at an increased risk if not traced in a timely manner, possibly resulting in mortality. , Thesis (MPH) -- Faculty of Health Sciences, 2022

- Description: Introduction: The emergence of the coronavirus disease of 2019 (Covid-19) has wrought profound and enduring transformations in global health, economic dynamics, and social interactions. However, the comprehensive quantification of the psychological repercussions of the Covid-19 pandemic remains elusive and is poised to compound the preexisting burden of mental health disorders within the general populace. Elevated transmission rates, rapid disease progression within vulnerable demographics, and the absence of definitive curative or preventive measures have collectively contributed to a heightened worldwide state of stress and anxiety. Extensive research has demonstrated that the apprehension and stress associated with Covid-19 are markedly pronounced among healthcare professionals, commonly referred to as front-line workers, in comparison to the general population. The Covid-19-related psychological distress is anticipated to act as a catalyst, exacerbating mental health conditions within high-risk groups. Aims and Objectives: This study endeavours to ascertain the prevalence and severity of depression, anxiety, and post-traumatic stress disorder (PTSD) among medical doctors and nurses employed at a regional hospital in South Africa. Methodology: A cross-sectional investigation was conducted to evaluate the presence of anxiety, depression, and stress symptoms among medical doctors and nurses working at a Regional Hospital situated in the Free State Province of South Africa. A purposive sample of 200 participants, comprising all willing doctors and nurses employed at the study site, was enrolled in the study. Findings: The participants exhibited an average age of 42 years and an average tenure of approximately 72 months at the hospital. The majority of participants were of African descent, with a male-to-female ratio of 1:2.3. Female healthcare workers reported significantly higher instances of PTSD than their male counterparts. In the aggregate, 71.4percent of doctors reported symptoms indicative of depression, 73.2percent reported anxiety-related symptoms, and 19.6percent reported PTSD-related symptoms. Among nurses, 72percent displayed clinically significant symptoms of depression, 81percent exhibited anxiety-related symptoms, and 27.7percent manifested symptoms suggestive of PTSD. A moderately robust positive correlation was discerned between PTSD and Anxiety (p = .000; r = .466) as well as PTSD and Depression (p = .000; r = .315). Additionally, a strong positive correlation was identified between Anxiety and Depression (p = .000; r = .631). A statistically significant disparity (p = .030) in anxiety levels was observed among workers in different risk-prone areas. Nurses reported substantially higher levels of anxiety (p = .039; M = 10.63, sd = 4.03) compared to doctors (M = 9.01, sd = 3.80) and administrators (M = 10.50, sd = 4.32). Moreover, both nurses (M = 27.06, sd = 13.61) and administrators (M = 33.33, sd = 14.44) exhibited significantly higher instances of PTSD (p = .003) than doctors (M = 19.96, sd = 15.03). Conclusions: The healthcare workers under scrutiny reported elevated levels of anxiety and depression attributable to the Covid-19 pandemic, although the prevalence of posttraumatic stress symptoms was comparatively lower within the hospital setting. Furthermore, this study illuminates that depressive, anxiety, and post-traumatic stress symptoms were more prevalent among nurses than doctors. Additionally, healthcare professionals operating in high-risk Covid-19 environments, such as the Covid-19 ward, demonstrated heightened levels of anxiety when juxtaposed with their counterparts stationed in low-risk Covid-19 areas within the healthcare facility. , Thesis (MPH) -- Faculty of Health Sciences, 2022

- Description: The purpose of this study was to explore and describe the knowledge, attitude and psychosocial experiences of health care workers regarding Covid-19 in Buffalo City Municipality. Covid-19 is a disease that attacks the respiratory system and functions. It is a highly infectious disease with a lengthy 5-6 sometimes even 14-day incubation period. It is very serious condition and has killed a lot of people including the Health Care Workers A qualitative descriptive explorative contextual design was employed in this research study. The design was relevant for this study to explore and describe the knowledge, attitude, and psychosocial experiences of health workers regarding Covid-19 in Buffalo City Municipality. The non-probability sampling method was used and a convenient sampling technique was used to select the participants. Professional nurses who met the criteria and who were on duty on the day of data collection were included in the study. The researcher interviewed 15 professional nurses and stopped as the data was saturated. A semi-structured Interview guide was used as an instrument to collect data containing open-ended questions. The researcher maintained ethical principles throughout the study. Concepts of trustworthiness of the study were applied throughout the research. Tech’s eight steps approach was used to guide the data analysis process. The findings of this study indicate that health care workers have a high level of knowledge about Covid-19. They know what Covid-19 is, how it started, its signs and symptoms, how to protect themselves from it and its complications. Negative attitudes, fears were noticed from the HCWs and thus the need for psychological support was identified. Feelings of neglect and lack of motivation were also identified. Psychological support for health care workers must be provided to prevent staff burnout. Personal Protective Equipment used in the hospital premises must be left and washed in the hospital laundry to prevent the spread of infection to the families of the HCWs. It was indicated that there are health care workers who experienced chronic illnesses after being diagnosed with Covid-19. These chronic illnesses include diabetes and high blood pressure. It was brought to light that myths circulating on the social media about Covid-19 vaccines are delaying the end of Covid-19 epidemic by putting the health care workers at risk of being infected with it as they will be expected to treat patients diagnosed with Covid-19; therefore, government should develop a policy that will limit people from spreading things that they are not true and cannot prove. In conclusion, community awareness and forced vaccination are recommended to end the Covid-19 virus. Monitory incentives should be provided to motivate health care workers. Their overtime that they have worked during Covid-19 must be paid. The Department of Health and hospital managers must make sure that working conditions are improved. This includes the availability of machines to test for Covid-19. More research needs to be done to find out why some people who were diagnosed with Covid-19 end up having chronic illnesses that they never had previously. , Thesis (MPH) -- Faculty of Health Sciences, 2020
