How simian foamy virus spreads from primates to people

Epidemiological and Molecular Aspects of the Interspecies Transmission of Foamy Viruses From Monkeys to Humans: A Model of the Early Stages of Viral Emergence.

Observational Institut Pasteur · NCT03225794

This project will test whether people living in rural Cameroon who have contact with nonhuman primates carry simian foamy virus and how often it jumps to humans.

What this trial studies

Researchers will perform microbiological monitoring of people aged 5 and older living in rural zones of Cameroon to detect simian foamy virus infection. Participants will provide informed consent and biological samples that are screened for viral markers and sequenced when positive. The work links human sample results with patterns of animal contact to document early cross‑species transmission events. Findings will be analyzed at Centre Pasteur du Cameroun to map occurrence and genetic relationships between primate and human viruses.

Who should consider this trial

Good fit: Ideal candidates are people aged 5 years and older living in rural areas of Cameroon who may have contact with nonhuman primates and can provide written consent.

Not a fit: People younger than 5, those not living in the target rural areas of Cameroon, or individuals without primate exposure are unlikely to benefit from participation.

Why it matters

Potential benefit: If successful, this work could identify early human infections and guide prevention efforts to reduce future viral emergence from primates.

How similar studies have performed: Previous observational work in Central Africa has detected simian foamy virus in people exposed to primates, so the approach is established though still limited in scope.
