StaphNET-SA Second survey
Staphylococcus aureus bloodstream infections are among the leading causes of infectious disease associated morbidity and mortality worldwide. Understanding the population dynamics and evolution of circulating S. aureus lineages is essential to guide infection prevention strategies, antimicrobial stewardship, and public health policies; however, genomic surveillance studies in South America remain limited. The StaphNET-SA network was created for installing the genomic surveillance of Staphylococcus aureus in South America, and during 2019 conducted a first genomic epidemiology survey of both MRSA and MSSA causing bacteraemia. The aim of this follow up study was to conduct a second survey to characterize the geographical and temporal dynamics of MSSA and MRSA causing bacteraemia and their epidemic patterns in the region during COVID19. This data is part of a pre-publication release.
