Trends, Seasonality, and the Impact of COVID-19 on Clinical Staphylococcus aureus and MRSA Isolates in Western Mexico (2016–2025): A Time-Series Analysis at a University Referral Hospital
MRSA declined markedly across the study period, with the steepest reduction following the Omicron peak. The decline persisted after adjustment for pandemic-related fluctuations in hospital volume, supporting periodic reassessment of empiric anti-MRSA prescribing policies in similar settings.
