Prevalence and Covid-19 Testing (Published)
An outbreak of pneumonia of unknown etiology in Wuhan City, Hubei Province, China was initially reported to the World Health Organization in December 2019. Global health authorities purportedly identified a novel coronavirus (SARS-CoV-2) which continues to effect most of the world. Diagnostic testing for SARS-CoV-2 continues to advance and interpreting test results is paramount. The most commonly used diagnostic test has been the reverse transcriptase polymerase chain reaction amplification. Determining test precision not only depends on operating characteristics, sensitivity and specificity, but more importantly on prevalence of the infectious in the population tested. This paper develops a numerical optimizer (model) to explore the effect of prevalence on surveillance testing accuracy. Findings herein suggest that large scale COVID-19 surveillance testing should be curbed or eliminated. Results advocate a more flexible and narrowly targeted approach to testing strategies.
The Impact of Covid-19 Induced Capital Flight on the Bond and Foreign Exchange Markets In Ghana (Published)
This paper provides evidence on the adverse effects of Covid-19 induced capital flight on the bond and foreign exchange markets in Ghana. Based on trend analysis, the study found significant portfolio reversals after the country recorded its first case of Covid-19 on March 12, 2020. This excessive capital flight had a far-reaching adverse impact on nominal exchange rate. Precisely, the Ghanaian Cedi shed earlier gains recorded in the first half of the year against the US Dollar. The prime contribution of this study is that it provides insight into the impact of the Covid-19 pandemic on the bond and foreign exchange markets in Ghana. To the best of our knowledge, this study is novel in the sense that no prior study has examined the response of the domestic bond market and nominal exchange rate to unanticipated global shocks in Ghana. The findings imply that, over-reliance on foreign portfolio inflows renders the bond and foreign exchange market vulnerable to unanticipated external shocks. Thus, the Covid-19 pandemic is a wake-up call for operationalization of policies to strategically develop the domestic bond market in order to build a wider domestic investor base to cushion the Ghanaian economy from such shocks.
Education is a key player in addressing any social problem; it provides individuals with the necessary skills and knowledge to cope with any eventuality. Conceiving the fact that the school is a veritable tool to fixing the society in all spheres of life, including outbreak of diseases such as COVID-19, this study makes a case for Experiential Learning Theory (ELT) as an appropriate pedagogical approach so that information and facts about the disease can be brought to real life situations. Opinions and ideas on COVID-19 were obtained from secondary sources and analysed qualitatively leading to the suggestion that schools should reopen for students to leverage the opportunities which COVID-19 has presented to education.
The covid-19 pandemic as declared by WHO in March 2020 is a game changer that introduced a “new normal” of every facet of life, every sector of the economy and every cluster of the population. The key indicators of business plan and continuity, government policies and security imopacting logistics have been affected and in all affecting the short-term survival rate of the poultry industry.The analysis revealed that all proxies of covid-19 indicators such as business plan and continuity, government policies and security impacting logistics have a significant positive effect on the financial health of the poultry industry (Adjusted R2= 0.949, F-statistics = 5.512 : p= 0.000<0.05). Thus, the research concluded that a well-managed Covid-19 indicators and proxies have a significant positive effect on the financial health of the poultry industry in Nigeria.
Life-Distress and Work Burnout as Predictors of Organizational Reactions and Social-Emotional Stability of Nurses in Eastern Nigeria (Biafra) (Implications for Covid-19 Health-Care Givers/Providers) (Published)
The study examined life-distress and work-burnout as predictors of nurses’ organizational reactions and social-emotional stability in Eastern Nigeria (Biafra). A cluster-sampled 230 General Hospitals nurses in Anambra State between 25-48 years and SD 5.33 participated, in which valid/reliable instruments, predictive cross-sectional designs, and multiple regression statistics were adopted. Findings were: Life-distress has relationship with organizational reactions of the nurses. Burnout does not have relationship with nurses’ organizational reactions. Life-distress does not have relationship with nurses’ emotional stability. Burnout adversely affects nurses’ emotional stability. Life-distress will not lead to nurses’ organizational reactions. Life-distress will not lead to nurses’ emotional stability. Burnout will not lead to nurses’ organizational reactions. Low burnout will lead to nurses’ emotional stability. Recommendations: While encouraging nurses to develop work competencies for coping with life-distress and burnout, complimentary healthy psycho-organizational enablers should be established in hospitals. This will assist health-care givers cope with pressure of managing COVID-19 pandemic.

Media Dependency and Information-Seeking Behaviour of Uyo Residents during the Covid 19 Pandemic in Nigeria (Published)
This study examined media dependency and information-seeking behaviour of Uyo residents during the Covid-19 pandemic in Nigeria. The study adopted the survey research method with questionnaire as an instrument for gathering data. The population of the study comprised of Akwa Ibom State residents based on the 2018 National Population Commission (NPC) projected census figure of 2006 taken at 3.4% yearly growth rate which gave the figure as 4,828,267. The researcher adopted the multi-stage sampling technique to select respondents for the study. A sample size of 500 was chosen using Comprey and Lee’s sample guide. Out of 500 copies of the questionnaire distributed to respondents, 480 were returned and found useful for the study. The study found out that during health emergency situation like the covid-19 pandemic which was occasioned by anxiety, tension, fear and uncertainty, residents depended more on the media to obtain information that can help reduce tension and fear. The study recommends that the mass media should be objective, fair, honest and devoid of bias during health emergencies like covid-19 pandemic since a lot of media audience rely on them for health updates.
Coronavirus outbreaks affect human beings as a whole and can be a cause of serious illness and death. Machine learning (ML) models are the most significant function in disease prediction, such as the Covid-19 pandemic, in high-performance forecasting and used to help decision-makers understand future situations. ML algorithms have been used for a long time in many application areas that include recognition and prioritization for certain treatments. Too many ML furcating models are used to deal with problems. In this study, predict a pandemic outbreak using the ML forecasting models. The models are designed to predict Covid-19, depending on the number of confirmed cases, recovered cases and death cases, based on the available dataset. Support Vector Machine (SVM) and Polynomial Regression (PR) models were used for this study to predict Covid-19 ‘s aggressive risk. All three cases, such as confirmed, recovered and death, models predict death in Ethiopia over the next 30 days. The experimental result showed that SVM is doing better than PR to predict the Covid-19 pandemic. According to this report, the pandemic in Ethiopia increased by half between the mid of July 2020. Then Ethiopia will face a number of hospital shortages, and quarantine place.

Nigerians Perspectives on Covid-19 Pandemic and How It Affects Their Lifestyle and Financial Status (Published)
Covid-19 is a viral disease that originated from Wuhan province of China. The virus has rapidly crossed borders, infecting and killing people in many countries including Nigeria. Undoubtedly, the pandemic has massive impact on the activities of Nigerians, including social lifestyle and income. The age-long communal behavior of Nigerians, like attendance to religion gatherings, ceremonies, and sports, has been hampered due to covid-19 pandemic. Also, due to this pandemic, Nigeria´s economy has declined drastically. This study was conducted to understand the perspective of Nigerians about Covid-19, and how it affected their lifestyle and financial status. Method: An online survey was conducted using the combination of few open ended and closed ended questions to gather data from a total of 325 respondents in Nigeria. Results: Majority of the respondents had adequate knowledge about the Covid-19 infection, its preventive measures, and its mode of transmission. Furthermore, over half of the respondents admitted that the pandemic has adversely affected their social lifestyle and financial status. Conclusion: There is need for provision of financial assistance and distribution of palliatives to all Nigerians during this pandemic. The government should also ensure the safety of all citizens, as social vices increase amidst the pandemic. A policy against increment of price of commodities should be established and implemented.
The earlier studies have shown that zinc deficiency can hinder host-defense systems to increase the susceptibility to various viral and bacterial infections, and thus in view of the global COVID-19 pandemic, potential protective effect of zinc is of particular interest. As it has become clear that zinc deficiency is induced by the non-transferrin-bound iron (NTBI) based on the our works, the use of our non-toxic iron chelators can be recommended as the supportive treatment in therapy of COVID-19 infection, because our iron chelators may prevent the zinc deficiency by inhibiting the formation of iron deposition containing much iron and zinc ions through removing or controlling the iron(III) ions in NTBI.
The Chinese government is heavily promoting traditional Chinese medicines (TCM) as treatment for COVID-19 at present, but there are no rigorous trial data to demonstrate that the remedies work. Based on our recent works, we have elucidated the chemical properties of TCM, and have proposed the scientific origin of “Japan Paradox”.
Covid-19 Lockdown, Locus of Control and State Anxiety among Residents of Plateau State Nigeria (Published)
A total of 406 participants include 211 (52.0%) males and 195 (48.0%) females participated in this study. Three (3) hypotheses were tested using linear regression at 0.05 significant level. Findings of the study revealed that, the value of the calculated statistic of COVID-19 lockdown was significant, t = 7.070, p = 0.000 (p <.05). The value of calculated statistics of internal locus of control was not significant, t = 1.708, p = 0.088 (p>.05). Furthermore, the value of calculated statistics of external locus of control was significant, t = -4.088, p = 0.000 (P<.05). The researchers conclude that mental health status of individuals should be taken into consideration during and after the COVID-19 pandemic. It is therefore, recommended that mental health practitioners such as clinical psychologists and psychiatrists should be included as part of the task force to address COVID-19 pandemic considering the possible increase of mental health challenges during and after the pandemic.

Stylistic Analysis of President Buhari’s Addresses of Nigerians in the Face of Covid-19 Pandemic (Published)
The role of language in any speech event cannot be overemphasized. Language is the vehicle through which political speeches are carried out. This study investigated two speeches of President Muhammadu Buhari during the coronavirus (Covid-19) pandemic to ascertain how he has employed language, the linguistic elements used and the stylistic and pragmatic imports. Using the theoretical framework of stylistics, the researcher found out that Buhari tactfully used words to address Nigerians on Covid-19 and stressed the measures to be taken to contain the spread of the virus. To achieve the pragmatic effect of his speeches, he used lexical devices such as transitional makers, repetition, alliteration, assonance, pronouns to project the theme/subject matter of the language discourse. It was found out that the speaker used coordination to denote relationship of grammatical units, show contrast and as a re-statement of what he said earlier. The speaker repeatedly used coordination in his speeches and this is commendable since in language, identical items may be conjoined in an indefinite number of times. The analysis revealed that president is committed in combating the coronavirus pandemic that is ravaging his nation.

A scoping review on epidemiology, etiology, transmission, clinical presentation, treatment and management of coronavirus disease (COVID-19) (Published)
Coronavirus (COVID-19) is a highly infectious disease which has posed serious threats to global health. This viral disease was discovered in late December 2019, in Wuhan, China. Infection rates due to the pandemic amounts to over 1 million globally while death rate is over 80,000. The United States, Italy and Spain are epicenters of the disease and have recorded more deaths due to the viral infection than other countries. Since the virus is spreading worldwide, on March 11, 2020, the WHO officially described the COVID-19 outbreak as a pandemic. The virus is transmitted when people interact with each other for some time in close proximity. Precisely, this review aims to provide the evidence of early findings on the etiology, transmission, symptoms, treatment and management of COVID-19.Studies have recorded Covid-19 infection in asymptomatic patients and in those with visible symptoms. Elderly people, pregnant women, people with underlining illness and compromised immune system are very susceptible to COVID-19 than other categories of people, however, reports of deaths of people without history of underlining illness has led to controversies. The diseased due to the virus should try to seek appropriate medical help and limit their exposure to other unaffected persons. Currently, there are no vaccines for the pandemic, but the FDA has recommended hydroxyl chloroquine as a therapy for COVID-19. The likelihood of transmission can be reduced by practising hygienic measures. Frequent disinfection and cleaning are advised for groups that are at risk of contracting the virus.
Based on the facts that non-toxic iron chelator SP10 and its homologues exhibit high anti-tumor, anti-bacterial, and anti-virus activity, we would like to propose that SP10 and its homologue can be Supplement against COVID-19, and another virus and unseen enemy which will appear in future
