What this trial studies

This observational study collects data to compare the outcomes of monkeypox (Mpox) in individuals living with HIV and those who are HIV-negative but on pre-exposure prophylaxis (PrEP). It aims to identify risk factors associated with specific outcomes of Mpox. Participants must have a confirmed Mpox diagnosis from PCR testing and be at least 18 years old. The study focuses on cases diagnosed more than 90 days prior to data collection.

Who should consider this trial

Good fit: Ideal candidates include individuals aged 18 and older who have been diagnosed with monkeypox more than 90 days prior and either live with HIV or are HIV-negative and on PrEP.

Not a fit: Patients diagnosed with monkeypox within the last 90 days or those whose diagnosis was based solely on clinical criteria may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide valuable insights into the risk factors and outcomes of monkeypox, potentially improving management strategies for affected individuals.

How similar studies have performed: While this study focuses on a specific population, similar observational studies have successfully identified risk factors and outcomes for infectious diseases, suggesting potential for meaningful findings.
