What this trial studies

This study is a prospective cohort investigation that aims to evaluate clinical and immune-metabolic factors associated with the risk and severity of monkeypox infection in Brazil. It plans to enroll at least 80 patients over a six-month period, with follow-up assessments conducted through decentralized visits for 90 days post-inclusion. The study will utilize viral genomic analysis and untargeted metabolomics to gather data on the infection's impact.

Who should consider this trial

Good fit: Ideal candidates include men and women aged 18 years and older with confirmed monkeypox infection.

Not a fit: Patients unable to provide informed consent or those deemed unsuitable for decentralized follow-up may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance understanding of monkeypox infection and improve management strategies for affected patients.

How similar studies have performed: While there have been studies on monkeypox, this specific observational approach focusing on immune-metabolic variables is relatively novel.
