Can we better understand mpox in young people?
NCT ID NCT05947786
First seen Aug 31, 2026 · Last updated Sep 01, 2026 · Updated 1 time
Summary
This study gathers information from routine medical care on infants, children, and adolescents under 18 with confirmed mpox infection. Researchers aim to collect standardized data on symptoms, treatments, and outcomes to better understand how the disease affects young people. The study may expand to include more detailed data collection and sub-studies if needed. It also tracks infants born to mothers infected with mpox during pregnancy to see if the virus passes to the baby.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If successful, this study could provide a clearer picture of how mpox affects young people, guiding better treatments and public health responses.
- What could go wrong
- As an observational study, it does not test a new treatment, so it cannot directly improve outcomes. Data collection depends on routine care, which may vary across sites.
