Conceitos essenciais
Vaccination status does not affect the infectivity timeline in children with COVID-19.
Resumo
The study focused on the infectivity timeline of children with COVID-19, regardless of vaccination status. Here is a breakdown of the key points:
- Findings:
- Half of children with COVID-19 were noninfectious 3 days after testing positive, irrespective of vaccination status.
- Return-to-school policies may not need to differ based on vaccine or booster status.
- Methodology:
- 76 children aged 7-18 were studied, with nasal swabs taken every other day for 10 days.
- Infectivity was determined by testing for cytopathic effect (CPE) in lab cultures.
- Duration of Infectivity:
- By day 3, half of the children were noninfectious.
- By day 5, less than 25% of children were infectious, regardless of vaccination status.
- In Practice:
- Current policies of isolation for five days post-positive test may be appropriate.
- Return-to-school policies may not need to consider vaccine or booster status.
- Comparison:
- Results align with a study in adults with the Omicron variant, showing no link between vaccination status and infectivity duration.
- Source:
- Led by Neeraj Sood, PhD, the study was published in JAMA Pediatrics on October 23.

"Our findings suggest that current policies requiring isolation for five days after a positive test might be appropriate, as the majority of children were not infectious by day 5."
