Article Synopsis
  • - The study aimed to explore long-term health outcomes in children and young people post-COVID-19, particularly focusing on post-COVID-19 condition (PCC) and incomplete recovery, comparing these outcomes with those from other non-SARS-CoV-2 infections.
  • - Conducted in Moscow, researchers followed two cohorts of pediatric patients with confirmed COVID-19 from two different time periods (Wuhan and Omicron variants) and compared them to a reference group of those with other infections but negative for SARS-CoV-2.
  • - Findings revealed that the incidence of PCC was significantly higher in the Wuhan variant group compared to the reference group, while the Omicron variant showed no significant difference in PCC outcomes when compared to the

Article Synopsis
  • - The study investigated the prevalence of post-COVID-19 condition (PCC) in adults and children who were hospitalized after contracting COVID-19, using a defined WHO standard and conducting follow-ups at 6 and 12 months post-discharge.
  • - Findings showed a PCC prevalence of 50% in adults and 20% in children at 6 months, decreasing to 34% and 11%, respectively, at 12 months; factors such as female sex and hypertension in adults, and neurological comorbidities in children were linked to higher PCC risk.
  • - The results highlight the importance of monitoring for ongoing health issues following COVID-19, particularly in higher-risk groups, as a significant number of individuals experienced

Objectives: This study aimed to estimate the impact of the COVID-19 pandemic on the circulation of non-SARS-CoV-2 respiratory viruses and the clinical characteristics of COVID-19 in hospitalized children.

Methods: A total of 226 and 864 children admitted to the Children's City Clinical Hospital with acute respiratory infection in September to November of 2018 and 2020 in Moscow were tested for respiratory viruses using multiplex polymerase chain reaction (PCR) and Mycoplasma pneumoniae/Chlamydia pneumoniae using enzyme-linked immunosorbent assay.

Results: The detection rate of non-SARS-CoV-2 viruses in 2020 was lower than in 2018, 16.
