Acceptability of COVID-19 vaccination among healthcare workers in Sudan.

Introduction: Several studies have investigated COVID-19 vaccine acceptability and hesitancy, especially among healthcare workers (HCWs). However, acceptability of the vaccine by HCWs in Sudan remains unclear. Aims: We investigated acceptability of the COVID-19 vaccine and its determinants among HCWs in Sudan. Methods: Using a semi-structured questionnaire, we conducted a web-based cross-sectional study of COVID-19 vaccine hesitancy and its associated determinants among healthcare workers in Sudan during March-April 2021. Results: A total of 576 HCWs responded to the survey. Mean age was 35 years. Females (53.3%), medical doctors (55.4%) and being located in Khartoum State (76.0%) each accounted for more than half of the participants. Absolute refusal of the COVID-19 vaccine was expressed by 16.0% of the respondents. Males were more than twice as likely to accept the vaccine as females. Lower acceptability was statistically significantly associated with the nurses (OR = 0.35, 95% CI: 0.15-0.82, P < 0.001), increased perceived harm from the vaccine (OR = 0.11, 95% CI: 0.05-0.23, P < 0.001), lack of confidence in the source of the vaccine (OR = 0.16, 95% CI: 0.08-0.31, P < 0.001) and lack of confidence in organizations or government sectors supervising the vaccination process (OR = 0.31, 95% CI: 0.17-0.58, P < 0.001). Conclusion: This study highlights a moderate level of COVID-19 vaccine acceptability among HCWs in Sudan. Special consideration should be given to addressing vaccine hesitancy among female HCWs and nurses.

The proportion and determinants of COVID-19 infection among medical doctors in Sudan, 2020: A cross-sectional survey.

Globally, frontline health care providers are among the most affected population group by the COVID-19 pandemic. Knowing the factors contributing to the transmission of COVID-19 infection among frontline health care providers is essential for implementing tailored control measures and protecting this vital population group. This study aimed to estimate the proportion and to identify factors associated with COVID-19 infection among medical doctors in Sudan. A web-based survey was used to collect data from medical doctors who were working in Sudan during the study period. Data were analyzed using SPSS® version 25; Descriptive analysis in terms of means (SD) for continuous variables, frequencies, and percentages with 95% CI for the categorical variable was conducted. Chi-square test and binary logistic regression for associations between the outcome variables (risk of exposure to COVID-19 infection and ever tested positive for COVID-19 infection) and independent variables (socio-demographic and infection control standards) were also performed. Out of 352 valid responses, 13.6% had tested positive for COVID-19 infection at least once during the pandemic. More than one-third have identified colleagues as the main sources of infection compared to 21% of patients (p-value < 0.04). Doctors who received training on COVID-19 were 60% less likely to have positive tests for COVID-19 (p-value <0.03), while lack of PPE and hand hygiene utilities had no statistically significant associations with testing positive for COVID-19 infection. In conclusion, a significant proportion of doctors have contracted COVID-19 infection from their colleagues. This calls for restricting infection control practices at hospitals, doctor's doormats, and any other shared places that allow day-to-day interaction between doctors and their colleagues. Also, urgent need for training doctors on COVID-19 infection control practices as it has been identified as the key protective factor.

Convalescent plasma as a treatment modality for coronavirus disease 2019 in Sudan.

Coronavirus disease 2019 (COVID-19) is a disease spreading rapidly in Sudan, the rest of the African continent and the world with no known definitive treatment or vaccines. However, among many treatment interventions being tested globally, beneficial effects and clinical improvements have been reported when convalescent plasma is used for treating COVID-19 patients. We prepared a guiding protocol for treating early to moderate COVID-19 patients with plasma transfusion from convalescent COVID-19 patients. This protocol was deduced based on previously published reports and studies that evaluated and tested convalescent plasma as a prospective therapy for COVID-19 patients. The protocol covers instructions on patient and donor selection criteria, plasma harvesting, plasma product specifications, dosage and precautions for convalescent plasma collection and transfusion process. Altogether, we prepared a treatment protocol that is tailored to the context of Sudan to be adopted by Sudan's health authority. Moreover, it will also provide reference for researchers to design open label clinical trials for convalescent plasma transfusion.
