| Popis: | In 2020, a considerable overlap occurred between the COVID-19 pandemic and seasonal dengue transmission in India. This study aimed to evaluate the effects of acute or recent infection with SARS-CoV-2 on the course and outcomes of dengue fever in children. We prospectively enrolled 44 children with a clinical and laboratory diagnosis of dengue fever. Assessment of acute and recent SARS-CoV-2 infection was done using reverse transcription–polymerase chain reaction and IgG antibody through ELISA. Children were grouped based on evidence of SARS-CoV-2 exposure and clinical severity, and outcomes were compared. The median age of the study cohort was 96 months (interquartile range [IQR]: 69–129 months). Fever (98%), vomiting (78%), abdominal pain (68%), hepatomegaly (68%), and edema (32%) were the common features. About two-thirds (N = 30) had severe dengue; 20 (45%) had dengue shock. Liver dysfunction (58%) and acute kidney injury (25%) were other major organ dysfunctions. Nineteen (43%) children stayed in the pediatric intensive care unit for a median duration of 5 days (IQR: 2–11 days). None had acute SARS-CoV2 infection; however, IgG against SARS-CoV-2 was detected in 15 (34%) cases. Children with recent exposure to SARS-CoV-2 showed a trend toward a lower incidence of acute kidney injury, fewer organ dysfunctions, and a lower frequency of invasive ventilation. Four children (9%) died; none of the deaths were in the SARS-CoV-2–exposed group. The present study exposes preliminary evidence that dengue fever might follow a less severe course in children with recent exposure to SARS-CoV-2 infection. However, it is pertinent to understand the antigenic similarity and cross-protective antibody response between the two viruses and their clinical relevance. |
