Prevalence and outcomes of neonates with severe COVID-19: An observational study at Children’s Hospital 1 in Ho Chi Minh City, Vietnam

Objective: To evaluate the impact of the severe COVID-19 pandemic on neonates and develop strategies to improve their outcomes. Methods: We conducted an observational cross-sectional study at Children's Hospital 1 (CH1) from July 25, 2021, to May 31, 2022. All neonates who had fever or respiratory symptoms or were born from mothers with COVID-19 and had a positive RT-PCR SARS-CoV-2 result would be included. We classified neonates with COVID-19 into 2 groups: mild/moderate and severe for analysis. Differences between groups were analyzed using Fisher's exact test/Chi-square test for categorical variables and Student's t-test/Wilcoxon Rank Sum test for continuous variables. Results: This study included 88 newborns who had positive RT-PCR SARS-CoV-2 results. The severity COVID-19 rate among neonatal cases was found to be 13.6% (12/88), with a corresponding mortality rate of 1.1% (1/88). All severe cases showed lung abnormalities as evident on chest X-ray images. In addition to respiratory symptoms, a higher incidence of gastrointestinal manifestations, such as vomiting and diarrhea, was observed in the severe group, indicating a compelling association. The administration of anticoagulant and anti-inflammatory drugs in the study group resulted in a satisfactory outcome with no significant complications. Conclusions: The COVID-19 pandemic has had a substantial impact on the well-being of neonates. The management of COVID-19 in this population presents significant challenges.
