Survival Time to COVID-19 Severity and Its Predictors in South Gondar Zone, North-West Ethiopia: A Prospective Cohort Study.

Background: Coronavirus disease is still a global public health emergency. Due to an inadequate healthcare system in low-income nations like Ethiopia, the pandemic has had a devastating impact. Despite this, information on the severity of COVID-19 and related difficulties in Ethiopia is sparse. Therefore, we aimed to determine the survival time to severity and predictors of COVID-19 in Northwest Ethiopia. Methods: A prospective follow-up study was conducted among 202 adult COVID-19 patients in the South Gondar zone treatment centers. Data were entered using EpiData version 3.1 and then exported to Stata 16 for analysis. Kaplan-Meier was used to estimate mean survival time, and Log rank tests were used to compare survival time between explanatory variable groups. A cox-proportional hazards regression model with a 95% confidence interval and a p-value of 0.05 was used to identify covariates associated with the outcome variable. Results: The patients' average age was 41.2 years. With an IQR of 4-7 days, the median time to COVID-19 severity was 5 days. The overall COVID-19 severity rate was 6.35 (95% CI: 5.17-7.86) per 100 person-days observed. Senior adult age group (51-59 years) (AHR = 3.59, 95% CI: 1.05, 12.23), elderly age group (≥60 years) (AHR = 2.11, 95% CI: 1.09, 12.67), comorbidity (AHR = 3.26, 95% CI: 1.48, 7.18), high blood pressure at admission (AHR = 4.36, 95% CI: 1.99, 9.54), and high temperature at admission (AHR = 5.60, 95% CI: 2.55, 12.46) were significantly associated with COVID-19 severity time. Conclusion and Recommendation: Patients with COVID-19 had a short median severity time, and factors like older age, comorbidity, high temperature, and high blood pressure were all independent predictors of severity time. Patients with high body temperature, blood pressure, comorbidity, and advanced age should be the focus of interventions to reduce progression time and improve clinical outcomes.

Community risk perception and barriers for the practice of COVID-19 prevention measures in Northwest Ethiopia: A qualitative study.

BACKGROUND: According to the World Health Organization, viral diseases continue to emerge and represent a serious issue for public health. The elderly and those with underlying chronic diseases are more likely to become severe cases. Our study sets out to present in-depth exploration and analyses of the community's risk perception and barriers to the practice of COVID-19 prevention measures in South Gondar Zone, Northwest Ethiopia. METHODS: A qualitative study was done in three districts of South Gondar Zone. Community key informants and health extension workers were selected purposely for in-depth interviews and focus group discussion. The interviews were conducted by maintaining WHO recommendations for social distancing and use of appropriate personal protective equipment. The sample size for the study depended on the theoretical saturation of the data at the time of data collection. The qualitative data generated from in-depth interviews and focus group discussions was transcribed verbatim and translated into English language and thematically analyzed using open code software version 4.02. RESULTS: Three main themes and five categories emerged from the narrations of the participants regarding the perceived barriers for the practice of COVID-19 prevention measures. A total of 9 community key informants (5 women development armies (HDA), 2 health extension workers (HEW), and 2 religious leaders participated in the in-depth interview, while two focus group discussions (7 participants in each round) were conducted among purposely selected community members. The age of the participants ranged from 24 to 70 years with the median age of 48 years. The major identified barriers for practicing COVID-19 prevention measures were the presence of strong cultural and religious practices, perceiving that the disease does not affect the young, misinformation about the disease, and lack of trust in the prevention measures. CONCLUSIONS: Socio-cultural, religious, and economic related barriers were identified from the participant's narratives for the practice of COVID-19 prevention measures in south Gondar Zone. Our findings suggest the need to strengthen community awareness and education programs about the prevention measures of COVID-19 and increase diagnostic facilities with strong community-based surveillance to control the transmission of the pandemic.

Effects of Vitamin D on COVID-19 Infection and Prognosis: A Systematic Review.

INTRODUCTION: Vitamin D status is related to risks of influenza and respiratory tract infections. Vitamin D has direct antiviral effects primarily against enveloped viruses, and coronavirus is an enveloped virus. The 2019 coronavirus disease had a high mortality rate and impacted the whole population of the planet, with severe acute respiratory syndrome the principal cause of death. Vitamin D can adequately modulate and regulate the immune and oxidative response to infection with COVID-19. The goal of this systematic review was thus to summarize and decide if there were a link between vitamin D status and COVID-19 infection and prognosis. METHODS: The protocol of this study is documented in the Prospero database and can be accessed with the protocol number CRD42020201283. PubMed and Google Scholar were used for a literature search from August 2020 to September 2020. We restricted the year of publication of reviewed articles to 2019-2020, and the selected language was English. Studies that used secondary data, feedback, or analysis of reviews were removed. To assess the standard of studies included, the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) method was used. RESULTS: Of the nine studies reviewed, seven (77.8%) showed that COVID-19 infection, prognosis, and mortality were correlated with vitamin D status. CONCLUSION: Most of the articles reviewed showed that blood vitamin D status can determine the risk of being infected with COVID-19, seriousness of COVID-19, and mortality from COVID-19. Therefore, maintaining appropriate levels of Vitamin D through supplementation or natural methods, eg, sunlight on the skin, is recommended for the public to be able to cope with the pandemic.
