Common skin infection due to Panton-Valentine leucocidin-producing Staphylococcus aureus strains in asylum seekers from Eritrea

Since late 2014, multiple cases of abscesses and boils due to methicillin susceptible Staphylococcus aureus (MSSA) expressing the Panton-Valentine leukocidin (PVL) were observed in Eritrean asylum seekers in Lausanne, Switzerland. Strains isolated from infected Eritrean and non-Eritrean patients were compared by whole genome sequencing (WGS) to determine whether these numerous cases results from an outbreak.
