NCT05947786

Brief Summary

The goal of this multicentre, observational study on mpox in infants, children and adolescents is to increase knowledge about mpox infection and its associated disease in infants, children and adolescents. This will be done through the development of a harmonized system that will allow standard collection of information on demographics, clinical symptoms, clinical course, treatments and outcomes. The study will be carried out in three potential phases: Phase 1 entails the rapid development of an online paediatric registry collecting anonymised data from routine care on infants, children and adolescents with laboratory-confirmed mpox virus infection. If warranted, the study will proceed to Phase 2, an enhanced observational study of children and adolescents with confirmed mpox virus infection, if more detailed prospective data collection would aid the public health response. There is also the potential to initiate Phase 3, comprising of nested sub-studies to investigate specific research questions in this population.

Outcome Measures

Primary Outcomes (1)

  • Proportion of participants with severe mpox.

    Severe mpox infection as measured by, for example, mortality, ICU admission, receipt of interventions

    Throughout study completion, expected 2 years from study start.

Secondary Outcomes (1)

  • Number of infants born to women infected with mpox in pregnancy, who are vertically infected with mpox.

    Throughout study completion, expected 2 years from study start.

Eligibility Criteria

Sexall
Healthy VolunteersNo
Age GroupsChild (0-17), Adult (18-64)
Sampling MethodNon-Probability Sample
Study Population

Infants, children and adolescents with laboratory-confirmed mpox infection, including adolescent girls who acquired mpox in pregnancy, and infants who acquired mpox through vertical transmission. Phase 1 participants' consent may not be necessary as data collected is anonymous, phase 2 observational study participation would require participants'/ parent or legal representative consent as data collected is pseudonymised.

You may qualify if:

  • all infants, children and adolescents aged \<18 years at the time of mpox diagnosis, with laboratory-confirmed mpox infection, as per national guidelines;
  • mothers of eligible infants who are diagnosed with mpox at 28days or less are included in the study to collect maternal data on pregnancy and delivery

You may not qualify if:

  • adolescents aged over 18 years old at mpox diagnosis.
