Trends and Dynamics of COVID-19 in Zimbabwe: Implications for Selected Sustainable Development Goals

This study analysed the spatial and temporal trends and dynamics of COVID-19 to understand their implications on Sustainable Development Goals (SDGs) in Zimbabwe. Data on daily cases and mortality rates of COVID-19 were collected from the Worldometer website, whilst data on lockdown measures and travel restrictions were collected from Zimbabwe's Ministry of Health and Child Care. Exploratory and confirmatory analyses were employed on statistical data. COVID-19 statistical data were first tested for normality using the Kolmogorov-Smirnov test. Subsequently, the non-parametric Mann-Kendal (M-K) test was performed to determine the monthly average number of new cases and deaths trend from March 2020 to February 2022 using XLSTAT (2020). The study shows a significant increase (p = 0.00, α= 0.05) in COVID-19 cases between March 2020 and February 2022. The trend is characterised by sharp increases associated with wave periods. Although the results show no correlation between stringency index and COVID-19 cases, periods of high stringency are associated with a slightly lower number of cases. The spatial trends show that highly populated areas have high numbers of patient cases. Indeed, the lockdown measures put in place, among other factors, contributed to controlling the spread of the virus. The trends and dynamics of COVID-19 in Zimbabwe have implications for achieving SDG 1, SDG 2, SDG 3 and SDG 6. Thus, there is a need to factor in the temporal and spatial realities of COVID-19 in making a policy framework for effective control of the pandemic and promotion of sustainable development. © The Editor(s) (if applicable) and The Author(s), under exclusive license to Springer Nature Switzerland AG 2023.

The stock market and NO2 emissions effects of COVID‐19 around the world

In this paper, we study the impact of the coronavirus disease 2019 pandemic in estimated panel vector autoregression models for 92 countries. The large cross‐section of countries allows us to shed light on the heterogeneity of the responses of stock markets and nitrogen dioxide emissions as high‐frequency measures of economic activity. We quantify the effect of the number of infections and four dimensions of policy measures: (1) containment and closure, (2) movement restrictions, (3) economic support, and (4) adjustments of health systems. Our main findings show that a surprise increase in the number of infections triggers a drop in our two measures of economic activity. Propping up economic support measures, in contrast, raises stock returns and emissions and, thus, contributes to the economic recovery. We also document vast differences in the responses across subsets of countries and between the first and the second wave of infections.

Seismic Observations in Bucharest Area with a Raspberry Shake Citizen Science Network

Technological advancements and the appearance of low-cost Raspberry Shake seismographs have enabled the development of citizen science seismic networks in many areas worldwide. These networks can help reduce seismic risk and increase citizens' understanding of seismology and earthquakes. Such a network exists in Bucharest, one of the cities in Europe that are struck and affected by strong Vrancea earthquakes. The paper aims to show that data from such networks can be used in both outreach programs and research studies. There are presented, for the first time, seismic observations collected over two years beginning in the summer of 2020 in the Bucharest area based on the low-cost seismometers from the citizen science Raspberry Shake network. A significant number of earthquakes from the Vrancea region were recorded by the Bucharest Raspberry Shake Seismic Network (BRSSN). Some of them were felt by Bucharest inhabitants. The National Institute for Earth Physics in Magurele (Romania) organizes educational events that promote geosciences among the population and presents the tools at its disposal for a better understanding of earthquakes and their effects, contributing this way to the development of the concept of citizen science. Citizens are the first witnesses to seismic events and the citizen science seismic network provides them with the first direct information about the event via web apps available for any internet-connected device. Their involvement as non-professional participants helps in providing data for scientists via questionnaire forms to improve scientific research for earthquake assessment. Since citizen seismometers are installed in urban areas, an analysis of the ambient seismic noise (ASN) was performed in addition to the analysis of recorded seismic events. The analysis indicates that the level of seismic noise is mainly controlled by human activities. At the same time, for one citizen seismometer installed in a school in Bucharest, the results show patterns of noise variations due to students' activity.

Impact of COVID-19 on Hospital Admissions, Health Status, and Behavioral Changes of Patients with COPD.

Introduction: Patient with chronic obstructive lung disease (COPD) have an increased risk of severe Coronavirus disease (COVID-19), which is why self-isolation was recommended. However, long periods of social isolation accompanied with limited access to health care systems might influence the outcome of patients with severe COPD negatively. Methods: Data from COPD and pneumonia patients at Charité-Universitätsmedizin, Berlin and the volume of endoscopic lung volume reduction (ELVR) from the German lung emphysema registry (Lungenemphysem Register e.V.) were analyzed from pre-pandemic (2012 to 2019) to pandemic (2020 and 2021) period. In addition, 52 patients with COPD GOLD IV status included in the lung emphysema registry received questionnaires during lockdowns from June 2020 to April 2021. Results: Admissions and ventilation therapies administered to COPD patients significantly decreased during the COVID-19 pandemic. Likewise, there was a reduction of ELVR treatments and follow-ups registered in German emphysema centers. Mortality was slightly higher among patients hospitalized with COPD during pandemic. Increasing proportions of COPD patients with GOLD III and GOLD IV status reported behavioral changes and subjective feelings of increasing COPD symptoms the longer the lockdown lasted. However, COPD symptom questionnaires revealed stable COPD symptoms over the pandemic time-period. Summary: This study reveals reduced COPD admissions and elective treatment procedures of COPD patients during pandemic, but a slight increase of mortality among patients hospitalized with COPD irrespective of COVID-19. Correspondingly, patients with severe COPD reported subjective deterioration of their health status probably caused by their very strict compliance to lockdown measures.

Covid-19 crisis in the Netherlands: "Only together we can control Corona"

The development and management of the Covid-19 outbreak in the Netherlands is described. The "intelligent lockdown" was aimed at minimizing new infections and limiting the number of deaths, while keeping the economy running as much as possible. Changes in consumer behavior, exit strategy, and lessons learned are considered. (PsycInfo Database Record (c) 2023 APA, all rights reserved)

Social Pressures Accompanying the Comprehensive Ban Measures to Prevent the Spread of Corona Virus (Covid-19) in the Hashemite Kingdom of Jordan

The study aims to identify the social pressures accompanying the comprehensive ban measures to prevent the outbreak of the coronavirus covid-19, and the study used the descriptive analytical method where the questionnaire tool was used, and the study population consisted of (404) graduate students, master and doctorates in the departments of the Faculty of Social Sciences at Mutah University. Male and female students for the academic year 2019-2020, the study sample was chosen by the intentional method provided them with e-mails on the (teams) technology, and their number was (244) students. The study reached the following major results: 1-The most common types of social pressures associated with the comprehensive ban that individuals experienced was their anxiety when they heard from the media about new HIV infections, where the arithmetic mean value reached (4.41), which is a high arithmetic average. 2-The least factors leading to the social pressures accompanying the comprehensive ban to prevent the spread of the Coronavirus as Covid 19, came in the last place, the paragraph represented by strengthening the curfew from the feeling of indifference among individuals within the Jordanian society, with an arithmetic average of (3.21). The study recommended a set of recommendations, the most important of which are 1-Thinking positively about spending free time at home, and then occupying yourself with useful hobbies. 2-Teaching children some useful life skills after the end of the ban period. © 2022 DSR Publishers/The University of Jordan.

Epidemics, Lockdown Measures and Vulnerable Populations: A Mixed-Methods Systematic Review of the Evidence of Impacts on Mother and Child Health in Low-and Lower-Middle-Income Countries.

BACKGROUND: The aim of this research was to synthetise the existing evidence on the impact of epidemic-related lockdown measures on women and children's health in low- and lower-middle-income countries (LLMICs). METHODS: A mixed-methods systematic review was conducted of qualitative, quantitative and mixed-methods evidence. Between 1st and 10th of November 2021, seven scientific databases were searched. The inclusion criteria were that the paper provided evidence on the impact of lockdown and related measures, focused on LLMICs, addressed impacts on women and child's health, addressed epidemics from 2000-2020, was peer-reviewed, provided original evidence, and was published in English. The Joanne Briggs Institute's critical appraisal tools were used to assess the quality of the studies, and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines for reporting. The evidence from the papers was grouped by type of lockdown measure and categories of impact, using a narrative data-based convergent synthesis design. RESULTS: The review process identified 46 papers meeting the inclusion criteria from 17 countries that focussed on the coronavirus disease 2019 (COVID-19) and Ebola epidemics. The evidence on the decrease of utilisation of health services showed plummeting immunisation rates and faltering use of maternal and perinatal services, which was linked to a growth of premature deaths. Impacts on the mental health of children and women were convincingly established, with lockdowns associated with surges in depression, anxiety and low life satisfaction. Vulnerability may be compounded by lockdowns, as livelihoods were disrupted, and poverty levels increased. CONCLUSION: Limitations included that searches were conducted in late-2020 as new research was being published, and that some evidence not published in English may have been excluded. Epidemic-related lockdown measures carry consequences for the health of women and children in lower-income settings. Governments will need to weigh the trade-offs of introducing such measures and consider policies to mitigate their impacts on the most vulnerable.

One year after the COVID-19 outbreak in Germany: long-term changes in depression, anxiety, loneliness, distress and life satisfaction.

Several studies have linked the COVID-19 pandemic to unfavorable mental health outcomes. However, we know little about long-term changes in mental health due to the pandemic so far. Here, we used longitudinal data from a general population sample of 1388 adults from Germany, who were initially assessed between April and May 2020 (i.e., at the beginning of the COVID-19 pandemic in Germany) and prospectively followed up after 6 (n = 1082) and 12 months (n = 945). Depressive and anxiety symptoms as well as loneliness did not change from baseline to 6-month follow-up. While anxiety symptoms did not change in the long run, depressive symptoms and loneliness increased and life satisfaction decreased from baseline to 12-month follow-up. Moreover, vulnerable groups such as younger individuals or those with a history of mental disorders exhibited an overall higher level of psychopathological symptoms across all assessment waves. Our findings suggest a deterioration in mental health during the course of the COVID-19 pandemic, which emphasizes the importance to implement targeted health promotions to prevent a further symptom escalation especially in vulnerable groups.

Stock market response to Covid-19, containment measures and stabilization policies—The case of Europe

Policymakers imposed constraints on public life to contain the Covid-19 pandemic. At the same time, fiscal, monetary and macroprudential policies implemented a large range of expansionary measures to limit the economic consequences of the pandemic and stimulate recovery. In this paper, we assess the response of the equity market as a high-frequency indicator of economic activity to containment and stabilization policies for 29 European economies. We construct indicators of containment and stabilization policies and estimate a range of panel VAR models. The main results are threefold. First, we find that stock markets are highly responsive to containment and stabilization policies. We show that domestic fiscal policy, macroprudential policy as well as monetary policy support the recovery as reflected in the stock market. Second, expansionary fiscal policy conducted at the European level reduces rather raises stock prices. Third, we estimate the model over subsamples and show that the counter-intuitive stock market response to EU policies is driven by the responses in medium- and high-debt countries. These countries' stock markets are also particularly susceptible to monetary policy announcements. © 2022 CEPII (Centre d'Etudes Prospectives et d'Informations Internationales), a center for research and expertise on the world economy

Covid-19 Lockdown Measures and Presumptive Taxation in Zimbabwe

This desktop study evaluated the effects of lockdown measures on Zimbabwe's presumed taxation. As a result of the COVID-19-induced health-care crisis, the Zimbabwean government, like many countries around the world, imposed a lockdown. This has diverse effects on various tax systems. This article examined the literature regarding the effects of lockdown measures on Zimbabwe's presumptive taxation. The study's methodology differed from the traditional approach to research as it focused more on literature review and the findings, conclusions and recommendations were based on the reviewed literature. The results showed that COVID-19-induced lockdown restrictions affected ZIMRA's presumptive tax collection and the livelihood of informal merchants. One of the factors that aggravated the harm was the short notice in declaring lockdown enforcement. According to the findings, it will take some time for presumptive tax collections to recover. To hasten this process, the Zimbabwean government must provide aid to small business owners to enable them resume operations. In addition, there is an urgent need to educate informal merchants about health risks such as COVID-19, and support from the formal sector and international donors should ensure that informal traders such as vegetable vendors, cobblers, and transport operators have protective equipment as recommended by medical experts so that they can continue to conduct business safely and pay their presumptive taxes in time.

INSTITUTIONAL ETHICS OF CARE IN SERBIA DURING THE COVID-19 PANDEMIC: A CASE STUDY ON THE EFFECTS OF THE LOCKDOWN MEASURES ON GIRLS AND WOMEN TRAFFICKING SURVIVORS

Extreme situations such as the COVID-19 pandemic transparently show all the shortcomings of the Serbian system that should, in theory, provide support and protection to citizens in such circumstances. A particularly demanding task was to determine and measure the well-being of individuals during the pandemic, especially those from marginalized groups whose needs are not the priority to the system even under regular circumstances, those on the bottom of the social hierarchy who cannot influence the policies that shape their daily lives, or the decisions of authorities that further reproduce social inequalities. The paper examines institutional ethics of care during the pandemic in Serbia through the analysis of the adequacy of lockdown measures and their effects on the girls and women trafficking survivors. Analysis of the data collected in semi-structured interviews with girls and women showed that three central elements of the institutional (ethics of) care: the purpose of care, recognition of power relations, and the need for pluralistic tailoring of care to meet individuals' needs, were not fulfilled during the pandemic and that the logic of institutional care has had a politicizing character in Serbia. © 2022, University of Belgrade - Institute for Philosophy and Social Theory.

An Empirical Study of the Impact of Lockdown Measures on the Presumptive Taxation of Zimbabwe: A Case Study of ZIMRA

Following the health-care crisis caused by COVID-19, the Zimbabwean government, like many others across the world, imposed a lockdown. This had varying degrees of impact on various tax systems. This research paper examined the effects of lockdown measures on Zimbabwe's presumptive taxation. The study adopted a quantitative research approach, and semi-structured questionnaires were used to obtain detailed data. The results showed that COVID-19-induced lockdown restrictions impacted Zimbabwe Revenue Authority's (ZIMRA’s) presumptive tax collection and the livelihood of informal merchants. Many factors exacerbated the situation, one of which was the short notice in declaring lockdown enforcement. The informal traders indicated that the COVID-19 lockdown measures had a negative impact on their revenue generation and demand for their goods and services. The COVID-19-induced lockdown measures resulted in a drastic fall in presumptive tax collections in 2020. The study recommends that the Zimbabwean government assist small company owners, empower them and enable them to restart their operations. Furthermore, there is an urgent need to educate informal merchants about health hazards such as COVID-19, and support from the formal sector and international donors should ensure that informal traders such as vegetable vendors, cobblers, and transport operators have protective equipment as recommended by medical experts so that they can safely continue to be in business for them to be able to pay their presumptive taxes in time without fail. © 2022 by the authors.

Impact of Lockdown Restrictions on Treatment of Leprosy: A Retrospective Analysis.

Context: Coronavirus disease 2019 (COVID-19) has shown the potential to affect the life of people all over the world either directly or indirectly. Aim: To assess the impact of lockdown measures on treatment of leprosy among patients who received treatment from a tertiary referral centre. Settings and Design: A retrospective study was conducted at the dermatology department of a tertiary referral centre. Materials and Methods: We did a retrospective analysis of case records of patients with leprosy who received treatment from our tertiary referral centre from 01 March 2020 to 31 May 2021. Results: During the 15-month period, 59 patients received multi-drug therapy (MDT) for leprosy from our centre. Thirty-two patients (54.2%) were already receiving MDT as on March 2020, and 27 others (45.8%) were diagnosed with leprosy and started on MDT during the period from March 2020 to May 2021. Two patients (3.4%) developed COVID-19 while on MDT. When lockdown measures were implemented, 12 patients (12/59, 20.3%) discontinued treatment, citing conveyance difficulties. Three patients (3/59, 5.1%) were lost to follow-up. Limitations: Small sample size and reliance on retrospective data from a single centre were the major limitations of the study. Conclusion: A conscious effort is needed from healthcare professionals and the government to ensure that implementation of national programmes is not adversely affected by the ongoing COVID-19 pandemic.

‘Everything’s the Same, Everything’s Halted’: Quarantine in a ‘Home’ for People Identified as Disabled

While many evaluations of the response from residential social services to the COVID-19 pandemic have pointed to high mortality rates and human rights violations, some have given a positive assessment of their performance. Whatever the verdict, it is a fact that the clients of residential social services were subject to stricter and longer lockdown measures than the rest of the population. Our ethnographic research describes the lockdown technologies used at Home F, a residential institution for people identified as disabled. Setting out from the assumption that freedom is not the antithesis of some united regulatory regime but is the result of the intersection of various repertoires and logics of influence, the research analyses the ‘passages’ that regulate relations between the clients and their surroundings before and during the pandemic. It shows that the regulatory mechanisms that were put in place to facilitate an effective pandemic response do not constitute a new apparatus but only an intensification of technologies already in place. With the aim of mitigating risk, they delegitimise the needs of clients, render relations dependent on obedience, and pass moralised judgements on behaviour. Such ‘pedagogical arrangements’ cause emotional suffering and do not leave much space for freedom. In the discussion in the article we link our findings to the current debates about the productivity of power and (post)critical pedagogy, concluding that while pedagogy necessarily accompanies the management of risks, a critical gesture that delegitimises the interests and opinions of the objects of pedagogy may not be the most appropriate pedagogical method available. © Sociologický ústav AV ČR, v. v. i., 2022.

The role of pre-pandemic depression for changes in depression, anxiety, and loneliness during the COVID-19 pandemic: Results from a longitudinal probability sample of adults from Germany.

BACKGROUND: The present study aims to delineate the role of preexisting depression for changes in common mental health problems during the COVID-19 pandemic. METHODS: Using mixed-effects linear regression models, we analyzed data on the course of depressive (Patient Health Questionnaire-2) and anxiety (Generalized Anxiety Disorder-2) symptoms as well as loneliness (three-item UCLA Loneliness Scale) in a subset of the Socio-Economic Panel Study, a large and nationally representative household panel study from Germany. Participants were assessed during the first COVID-19 wave in Germany (March 31 to July 4, 2020; n = 6,694) and prospectively followed up at the peak of the second COVID-19 wave (January 18 to February 15, 2021; n = 6,038). RESULTS: Overall, anxiety and depressive symptoms decreased, whereas loneliness increased from the first to the second COVID-19 wave. However, depressive symptoms increased and the surge in loneliness was steeper in those with versus without clinically relevant depressive symptoms in 2019 or a history of a depressive disorder before the COVID-19 pandemic. Anxiety symptoms remained stable throughout the pandemic in individuals with versus without clinically relevant depressive symptoms in 2019. Pre-pandemic depression was associated with overall higher depressive and anxiety symptoms and loneliness across both assessments. The stringency of lockdown measures did not affect the results. CONCLUSIONS: Our findings suggest that individuals with a history of depressive symptoms before the COVID-19 pandemic are at increased risk to experience an escalation of mental health problems due to the COVID-19 pandemic. Therefore, they might particularly profit from targeted prevention and early intervention programs.

[Anorexia nervosa: does the incidence increase during the coronavirus pandemic?] / Anorexia nervosa: Steigt die Inzidenz in der Coronapandemie?

Since the beginning of the coronavirus pandemic and the associated lockdown measures, the number of children treated in this children's hospital for eating disorders and in particular anorexia nervosa has significantly increased.An increased focus on the control of body weight with restrictive eating habits or otherwise induced weight loss (sport) can compensate for fears of loss of control. Thinking and behavioral patterns which are typical for anorexia can be assessed as dysfunctional coping strategies of the corona pandemic in order to regain control (in the sense of a substitute structure) but also as a means of coping better with feelings of depression and anxiety.

Preliminary Results of COVID-19 Restriction Measures on the Air Pollution Levels in the City Center of Athens, Greece

COVID-19 is evolving into one of the worst pandemics in recent history. The lockdown measures implemented worldwide to slow the spread of the COVID-19 pandemic have caused an unprecedented reduction in global economic activity. Strict lockdown measures came into force in Greece from March 23th 2020. This study aims to assess the changes in air pollution levels during the restriction measures in Athens, the city with the most COVID-19 cases in the whole country. Measurements in a central location during the lockdown (24/03/2020 -07/04/2020) were compared with levels during the pre-lockdown (19/02/2020 -11/03/2020) period. Urban air pollution markedly decreased but with substantial differences among pollutants. The most significant impact during the lockdown period was observed for the concentrations of carbon monoxide (CO) and nitrogen oxides (NOx) with reduction percentages of -47% and - 35%, respectively, compared to the pre-lockdown period. These air pollutants are mainly related to traffic emissions. A lower reduction was recorded for coarse particulate matters (PMio) (-24%), probably due to the existence of other local sources of emission along with secondary formation. Nevertheless, this result must be further examined in order to be interpreted. Additionally, meteorological parameters such as wind speed found to play a key role on the results as most air pollutants were negatively correlated with higher air velocities. The scope of this study is to provide short term air quality results to the existing literature, in order to enhance decision making on life quality improvement in respect to the urban environment. © 2022 American Institute of Physics Inc..

Assessing the impact of COVID-19 restrictions on the microbial quality of an urban water catchment and the associated probability of waterborne infections.

The World Health Organization reported that COVID-19 cases reached 611,421,786 globally by September 23, 2022. Six months after the first reported case, the disease had spread rapidly, reaching pandemic status, leading to numerous preventive measures to curb the spread, including a complete shutdown of many activities worldwide. Such restrictions affected services like waste management, resulting in waste accumulation in many communities and increased water pollution. Therefore, the current study investigated if lockdown impacted surface water microbial quality within an urban water catchment in South Africa. Using quantitative microbial risk assessment, the study further assessed changes in the probability of infection (Pi) with gastrointestinal illnesses from exposure to polluted water in the catchment. Escherichia coli data for 2019, 2020 and 2021 - pre-COVID, lockdown, and post-lockdown periods, respectively - were collected from the area's wastewater treatment management authorities. The Pi was determined using a beta-Poisson model. Mean overall E. coli counts ranged from 2.93 ± 0.16 to 5.30 ± 1.07 Log10 MPN/100 mL. There was an overall statistically significant increase in microbial counts from 2019 to 2021. However, this difference was only accounted for between 2019 and 2021 (p = 0.008); the increase was insignificant between 2019 and 2020, and 2020 and 2021. The Pi revealed a similar trend for incidental ingestion of 100 mL and 1 mL of polluted water. No statistically significant difference was observed between the years based on multiple exposures. Although the overall microbial load and Pi estimated within the catchment exceeded the local and international limits recommended for safe use by humans, especially for drinking and recreation, these were not significantly affected by the COVID-19 restrictions. Nevertheless, these could still represent a health hazard to immunocompromised individuals using such water for personal and household hygiene, especially in informal settlements without access to water and sanitation services.

Comparative Analysis of Pollutant Levels during Lockdowns Across Different Land-Use over the Emirate of Abu Dhabi, United Arab Emirates

The outbreak of the COVID-19 pandemic has had a significant effect on people all over the world, posing health, economic, and social threats to the entire human population. As a part of preventive measures, at the end of March 2020 the UAE promulgated various lockdown measures to reduce the risk of the pandemic, which have a major impact on its local air quality levels. This research investigates the effect of the lockdown measures on the levels of the air pollutants like NO2 and PM2.5in Abu Dhabi Emirate using air quality stations data for the months of March and April 2020. Overall, NO2 levels have fallen dramatically by a range of 19% to 60% across all land use areas within the Emirate. Conversely, PM2.5 levels varied during the lockdown in April 2020, with increases ranging from 31% to 65% in rural and suburban industrial areas and decreases ranging from 2% to 33% in urban and suburban population areas. It can be observed that the lockdown measures had a huge impact on the NO2 levels due to reduced transportation and human activities while PM2.5 levels displayed great variability. The statistical analysis shows a significant moderate positive relationship (rs 0.476) at 0.05 level between NO2 and traffic volume crossing Musaffah Bridge. © 2021 Geo Publishing, Toronto Canada.
