RESUMEN
Most pediatric patients with COVID-19 described in the literature have unusual or mild respiratory symptoms. Fever is usually a prominent feature. Cough is described frequently. Less common are sore throat, headache, productive cough, nausea, and diarrhea. Some studies estimate that children made up about 2% of the affected population. Nearly 1.2% of infected children need hospital treatment and some children require mechanical ventilation. The immune system in children is in its development stage, therefore the immune response to pathogens is different from adults.

RESUMEN
In this study, we investigated the seroprevalence of anti-hepatitis D virus (HDV) antibodies in hepatitis B surface antigen (HBsAg)-positive children after 25 years of obligatory vaccination of infants against hepatitis B virus. This cross-sectional study included 120 treatment-naïve HBsAg-positive children, with a male-to-female ratio of 1.8:1 and a mean age of 7.8 ± 3.8 years (range, 1-17 years). Mothers were positive for HBsAg in 96.6% of the cases. HBeAg-positive chronic infection was observed in 60% of the cases, HBeAg-positive chronic hepatitis in 12.5%, and HBeAg-negative chronic infection in 26.7%. Anti-HDV antibodies were not detected in any of the cases. Thus, there is a lack of anti-HDV antibodies in HBsAg-positive children, despite the current burden in adults.
