Clinico-Epidemiological Profile of Breakthrough COVID-19 Infection among Vaccinated Beneficiaries from a COVID-19 Vaccination Centre in Bihar,India

BackgroundWhen the whole world is fighting in an unprecedented pace against COVID-19 pandemic, the breakthrough COVID infections poise to dampen the rapid control of the same. We carried out this project with two objectives; first, to estimate the proportion of breakthrough COVID-19 infection among completely vaccinated individuals and second, to study the clinico-epidemiological profile of breakthrough COVID-19 infections among them.MethodsThis cross-sectional analytical study was conducted among 2703 fully vaccinated individuals from AIIMS, Patna COVID Vaccination Centre (CVC), Bihar, India. The participants were selected randomly using a systematic sampling technique from the list of beneficiaries maintained at the CVC. Telephonic interviews were made to collect the information by trained data collectors.ResultsA total of 274 fully vaccinated beneficiaries [10.1% (95% CI: 9.1%, 11.4%)] were diagnosed with breakthrough COVID-19 infection. The infections were more among males (10.4%) and the individuals aged ≤29 years (12.5%). The beneficiary categories, the healthcare-worker and the frontline-worker, were identified as predictors of the breakthrough COVID infections. Only one in three participants had adopted adequate COVID appropriate behaviour following the full vaccination. The majority of the breakthrough infections occurred during the second wave of COVID-19. The majority of the individuals with breakthrough infections were asymptomatic and no death was reported among them.ConclusionOne in every ten fully vaccinated individuals can get the breakthrough COVID infections. The healthcare-worker and the frontline-worker had independent risk of getting the breakthrough infections. Very few with breakthrough infections were serious and no death was reported among them.     

Growing Ignorance of COVID-19 Preventive Measures in Ethiopia: Experts' Perspective on the Need of Effective Health Communication Strategies

Despite the recent surge of COVID-19 infections in Ethiopia, we are observing a profound ignorance of preventive measures by the general public and leaders at different levels. This is presenting considerable challenges in the effort to contain and control the pandemic. We believe that the current health communication approach implemented by the health authorities and media outlets need to be redesigned to bring a sustainable COVID-19 preventive behavior. The purpose of this perspective paper, therefore, is to stimulate discussions on effective health communication strategy to help the public persistently practice COVID-19 preventive measures over the long term. We undertook a series of discussions amongst the authors in order to synthesize individual viewpoints into ‘experts'' perspective’ driven by our daily observations and our expertise in the health service research. In light of this, we suggested that an effective health communication strategy need to address context specific situations to avoid temptation to ignore the ramifications of this very serious pandemic. This strategy includes trying to make sense of daily reported COVID-19 cases, being highly selective regarding sources of information, and being sensitive and responsive to religious and cultural factors. The media, health professionals, and leaders need to teach us how to live with the pandemic informed by robust scientific sources.     

Prevalence of COVID-19 Vaccine Side Effects among Early-Vaccinated Healthcare Workers in Eastern Ethiopia

BackgroundThe Ministry of Health of Ethiopia launched the COVID-19 vaccination campaign in March 2021, with frontline healthcare workers as first-round recipients and a goal of vaccinating 20% of the population by the end of 2021. The study aims to estimate the prevalence of COVID-19 vaccination side effects among early vaccinated healthcare workers in Adama hospital medical college.MethodsA cross-sectional study was carried out between March and June 2021, following the vaccination of COVID-19 vaccine among healthcare workers in Adama hospital medical college. The study used a structured self-administered questionnaire and additional telephone surveys on items covering the participants'' demographic data, local and systemic manifestations after vaccination.ResultsA total of 540 health care workers and supportive staff were enrolled in this study. The overall any-symptom report after the first dose of ChAdOx1 nCoV- 19 vaccine was 84.3%. The majority (39.6%) of participants had both systemic and local symptoms and 25.7% had only local and 18.9% had only systemic symptoms. Injection site pain was the most prevalent side effect symptom (64.1%), followed by fatigue (35.7%), headache (28.9%), joint pain (26.5%), and muscle pain (21.5%).ConclusionVaccine side effects were common and found to be well-tolerated among the recipients of the first dose of ChAdOx1 nCoV-19 at Adama hospital medical college healthcare workers. The side effects were mainly mild to moderate. More side-effect profiles should be studied and disseminated to detect rare adverse reactions.     

Duration of Supplemental Oxygen Requirement and Predictors in Severe COVID-19 Patients in Ethiopia: A Survival Analysis

BackgroundWith the rising number of new cases of COVID-19, understanding the oxygen requirement of severe patients assists in identifying at risk groups and in making an informed decision on building hospitals capacity in terms of oxygen facility arrangement. Therefore, the study aimed to estimate time to getting off supplemental oxygen therapy and identify predictors among COVID-19 patients admitted to Millennium COVID-19 Care Center in Ethiopia.MethodsA prospective observational study was conducted among 244 consecutively admitted COVID-19 patients from July to September, 2020. Kaplan Meier plots, median survival times and Log-rank test were used to describe the data and compare survival distribution between groups. Cox proportional hazard survival model was used to identify determinants of time to getting off supplemental oxygen therapy, where hazard ratio (HR), P-value and 95%CI for HR were used for testing significance and interpretation of results.ResultsMedian time to getting off supplemental oxygen therapy among the studied population was 6 days (IQR,4.3–20.0). Factors that affect time to getting off supplemental oxygen therapy were age group (AHR=0.52,95%CI=0.32,0.84, p-value=0.008 for ≥70 years) and shortness of breath (AHR=0.71,95%CI=0.52,0.96, p-value=0.026).ConclusionAverage duration of supplemental oxygen therapy requirement among COVID-19 patients was 6 days and being 70 years and older and having shortness of breath were found to be associated with prolonged duration of supplemental oxygen therapy requirement. This result can be used as a guide in planning institutional resource allocation and patient management to provide a well-equipped care to prevent complications and death from the disease.

Socio-demographic disparities in the eating behaviour of Malaysian children during the COVID-19 lockdown

ObjectivesThis cross-sectional study aimed to investigate the eating behaviour of Malaysian children aged 2 to 11 years old during the Movement Control Order (MCO) due to the coronavirus disease 2019 pandemic.Methods A total of 204 Malaysian parents of children aged 2 to 11 years old were recruited for this study using a combination of purposive and snowball sampling approaches. Parents were required to fill an online questionnaire hosted on Google Forms, which consisted of socio-demographic characteristics (including child’s gender, age, and ethnicity, as well as parental income during the MCO) and a 35-item list from the Children’s Eating Behaviour Questionnaire (CEBQ). Data analysis was conducted by further stratifying the children''s eating behaviour according to socio-demographic characteristics.Results No significant differences were observed in the eating behaviour of the children across age and parental income groups during the MCO. Malaysian Indian children had significantly lower mean scores for the food responsiveness (2.50±0.64) and emotional over-eating (2.13±0.72) subscales than Malaysian Chinese children. Girls had a significantly higher mean score for the slowness in eating subscale during the MCO than boys.Conclusion Children’s eating behaviour were comparable across socio-demographic characteristics. Nonetheless, the findings of the current study provide an overview of Malaysian children''s eating behaviour during the MCO.     

Preventive Practice and Associated Factors towards COVID-19 among College Students in Amhara Region,Ethiopia: A Cross-Sectional Study

BackgroundEthiopia has taken unprecedented preventive measures like closure of higher education institutions to halt the spread of COVID-19. However, still, there is scarce information regarding the knowledge, attitude, and practice (KAP) of students towards COVID-19 pandemic. Thus, this study aimed to assess the KAP and associated factors of preventive measures against COVID-19 among students.MethodsA cross-sectional study was conducted on 422 students. The sample was proportionally allocated into the randomly selected four colleges, and the students were recruited using a systematic random sampling technique. Variables with p-value < 0.25 in the bivariate logistic regression analysis were entered into the multivariable logistic regression model.ResultsThis study involved 408 students with response rate of 96.6%. The levels of good knowledge, positive attitude and good practice towards COVID-19 were 69.6%, 56.6% and 65% respectively. After adjusting for covariates, being in the late adolescent age group (16–20), living with > 5 family size, and being single were predictors of knowledge level. Besides, being single, attending diploma (TVET) level trainings, and being year-two students were predictors of attitude levels. Similarly, urban residence, being regular students, and being year-one students were the independent predictors of practice level of students.ConclusionIn this study, only two-third of the students had good preventive practice level towards COVID-19, which is below the Organization''s recommendation. Thus, the national, regional and local governments should develop effective and inclusive prevention strategies to address students who are at home due to COVID-19 pandemic.     

Strategic response to COVID-19 in Ethiopia

COVID-19, the novel coronavirus, has posed a major threat to low- and middle-income countries (LMICs) due to inadequate health infrastructure and human resources. Ethiopia, a low-income country with the second largest population in Africa, has coordinated a strategic response, leveraging existing infrastructure and health systems and mobilizing public health professionals and specialist expert physicians for a multifaceted, unified government approach and adaptive response. Resource limitations, particularly in critical care, have still posed challenges, but the public health and clinical interventions thus far have prevented the catastrophic toll that many predicted. As the pandemic continues, Ethiopia expects to use a triple care model integrated at all levels, consisting of COVID-19 care, isolation care for suspected cases, and essential health services, and urges intensified non-pharmaceutical interventions alongside equitable global vaccine distribution as the ultimate answers to pandemic control. This paper draws on existing data, national planning and guidelines, and expertise from health leadership to describe this response in hopes of providing an example of how future large-scale health challenges might be faced in LMICs, using Ethiopia’s successes and challenges in facing the pandemic.     

COVID-19 and Routine Childhood and Adolescent Immunizations: Evidence from Louisiana Medicaid

The COVID-19 pandemic disrupted routine vaccinations for children and adolescents. However, it remains unclear whether the impact has been different for children and adolescents from low-income families. To address this, we compared monthly routine vaccination use per 1000 vaccine-eligible children and adolescents enrolled in Louisiana Medicaid in the years before (2017–2019) and during the COVID-19 pandemic (2020). Compared to the 2017–2019 average vaccination rates, we found a 28% reduction in measles, mumps, and rubella (MMR), a 35% reduction in human papillomavirus (HPV), and a 30% reduction in tetanus, diphtheria, pertussis (Tdap) vaccinations in 2020. Vaccine uptake was lower in April 2020 after the declaration of a state of emergency and in late summer when back-to-school vaccinations ordinarily occur. We found little evidence of recovery in later months. Our findings suggest that a substantial number of disadvantaged children may experience longer periods of vulnerability to preventable infections because of missed vaccinations.     

The public health response to the COVID-19 pandemic for people with disabilities

With the rapidly changing landscape of the COVID-19 outbreak, how to best address the needs and continue to protect the health and well-being of people with disabilities (PwDs) is a global public health priority. In this commentary we identify three public health areas of ongoing need and offer possible strategies to address each. These areas include: the types of data that would help clarify risks for PwDs and help assure their safety long term; the prevention, treatment and mitigation measures for PwDs that are needed through the duration of the outbreak; and the issues of equity in access to and quality of medical care for PwDs. Because of the rapid nature of the public health response, it is critical to reassess and readjust our approach to best address the needs of PwDs in the months and years to come and to incorporate these new practices into future emergency preparedness responses.     

La obesidad como factor de riesgo en personas con COVID-19: posibles mecanismos e implicaciones

Recent reports suggest that obesity is a risk factor for more severe coronavirus disease. This article summarizes the available scientific evidence on the role of obesity in COVID-19. We focus on implications for younger patients and the proposed biological mechanisms that could explain both the higher risk observed and the possible higher contagiousness of people with obesity. We consider implications of the pandemic for people with obesity in relation to: difficulties in managing hospitalized patients, implications of confinement for the control and treatment of obesity, and the stigma people with obesity suffer, that could increase should the relationship between obesity and COVID-19 be confirmed. Understanding the role of obesity in COVID-19 should be a public health priority, given the high prevalence of this condition in our country.     

Lack of association between vaccination rates and excess mortality in Cyprus during the COVID-19 pandemic

BackgroundIt has been claimed that COVID-19 vaccination is associated with excess mortality during the COVID-19 pandemic, a claim that contributes to vaccine hesitancy. We examined whether all-cause mortality has actually increased in Cyprus during the first two pandemic years, and whether any increases are associated with vaccination rates.MethodsWe calculated weekly excess mortality for Cyprus between January 2020 and June 2022, overall and by age group, using both a Distributed Lag Nonlinear Model (DLNM) adjusted for mean daily temperature, and the EuroMOMO algorithm. Excess deaths were regressed on the weekly number of confirmed COVID-19 deaths and on weekly first-dose vaccinations, also using a DLNM to explore the lag-response dimension.Results552 excess deaths were observed in Cyprus during the study period (95% CI: 508–597) as opposed to 1306 confirmed COVID-19 deaths. No association between excess deaths and vaccination rates was found overall and for any age group except 18–49 years, among whom 1.09 excess deaths (95% CI: 0.27–1.91) per 10,000 vaccinations were estimated during the first 8 weeks post-vaccination. However, detailed cause-of-death examination identified just two such deaths potentially linked to vaccination, therefore this association is spurious and attributable to random error.ConclusionsExcess mortality was moderately increased in Cyprus during the COVID-19 pandemic, primarily as a result of laboratory-confirmed COVID-19 deaths. No relationship was found between vaccination rates and all-cause mortality, demonstrating the excellent safety profile of COVID-19 vaccines.     

Calcifediol Treatment and Hospital Mortality Due to COVID-19: A Cohort Study

Context. Calcifediol has been proposed as a potential treatment for COVID-19 patients. Objective: To compare the administration or not of oral calcifediol on mortality risk of patients hospitalized because of COVID-19. Design: Retrospective, multicenter, open, non-randomized cohort study. Settings: Hospitalized care. Patients: Patients with laboratory-confirmed COVID-19 between 5 February and 5 May 2020 in five hospitals in the South of Spain. Intervention: Patients received calcifediol (25-hydroxyvitamin D₃) treatment (0.266 mg/capsule, 2 capsules on entry and then one capsule on day 3, 7, 14, 21, and 28) or not. Main Outcome Measure: In-hospital mortality during the first 30 days after admission. Results: A total of 537 patients were hospitalized with COVID-19 (317 males (59%), median age, 70 years), and 79 (14.7%) received calcifediol treatment. Overall, in-hospital mortality during the first 30 days was 17.5%. The OR of death for patients receiving calcifediol (mortality rate of 5%) was 0.22 (95% CI, 0.08 to 0.61) compared to patients not receiving such treatment (mortality rate of 20%; p < 0.01). Patients who received calcifediol after admission were more likely than those not receiving treatment to have comorbidity and a lower rate of CURB-65 score for pneumonia severity ≥ 3 (one point for each of confusion, urea > 7 mmol/L, respiratory rate ≥ 30/min, systolic blood pressure < 90 mm Hg or diastolic blood pressure ≤ 60 mm Hg, and age ≥ 65 years), acute respiratory distress syndrome (moderate or severe), c-reactive protein, chronic kidney disease, and blood urea nitrogen. In a multivariable logistic regression model, adjusting for confounders, there were significant differences in mortality for patients receiving calcifediol compared with patients not receiving it (OR = 0.16 (95% CI 0.03 to 0.80). Conclusion: Among patients hospitalized with COVID-19, treatment with calcifediol, compared with those not receiving calcifediol, was significantly associated with lower in-hospital mortality during the first 30 days. The observational design and sample size may limit the interpretation of these findings.     

Clinical Characteristics and Outcomes of Patients with COVID-19 Infection and Acute Ischemic Stroke at Eka Kotebe General Hospital in Addis Ababa,Ethiopia

BackgroundAcute ischemic stroke has been reported to occur in a significantly higher number of COVID-19 patients as compared to healthy controls with variable proposed pathophysiologic mechanisms. To our knowledge, sufficient data regarding this subject is lacking in Ethiopia and the African continent at large. In this case series, we report the clinical characteristics and management of 5 cases with COVID-19 infection and acute ischemic stroke to shed light on the diagnostic and therapeutic challenges in resource-limited setups.MethodsThis is a case series including data collected from the medical records of 5 participants with confirmed RT-PCR positive COVID-19 infection and radiologically confirmed acute ischemic stroke, admitted at Eka Kotebe General Hospital Intensive Care Unit (ICU) in Addis Ababa, Ethiopia from June 10, 2020, to November 04, 2020.ResultsCryptogenic stroke was documented in 4/5 participants included in this series with the most common vascular risk factors identified for stroke being hypertension and diabetes mellitus. The median time from onset of COVID-19 symptoms to the identification of stroke was 07 days. Two fifth of the participants in this series died during their ICU admission with the immediate cause of deaths reported to be related to the severe COVID-19 infection but not stroke.ConclusionCryptogenic stroke was documented in 4/5 patients in this series despite the presence of vascular risk factors for other stroke subtypes. The overall prevalence, subtypes, and outcomes of stroke in COVID-19 patients in Ethiopia and the African continent as a whole needs additional research to elucidate the local burden of the disease and define the predominant pathophysiologic mechanisms for stroke in COVID-19 in the region.
