Observational, Prospective, Cohort Study of Mpox Infection in Brazil (NETPOX)

Observational, Prospective, Cohort Study of Mpox Infection in Brazil - NETPOX Cohort

The study is a prospective cohort that evaluates the clinical and immune-metabolic variables that may be linked to the risk and severity of the infection or even hospitalization or death in patients infected with the Mpox virus in Brazil. The expectation is to include at least 80 patients over six months, with a follow-up of 90 days from inclusion, through contact via decentralized visits.

Cohorts and Interventions

Group / Cohort	Intervention / Treatment
Human cases of monkeypox confirmed by PCR; Laboratory-confirmed mpox infection is defined as determined by polymerase chain reaction assay (PCR), culture, or antigen test obtained from a sample collected from blood, oropharynx, anal or skin lesion within 5 days of inclusion.	Diagnostic test: Viral genomic; Evaluation of mpox viral genomic; Diagnostic test: Untargeted Metabolomics; Evaluation of metabolomics of the total plasma, oropharynx, and skin samples.
