Description
Ruoyu Li and four colleagues model how MRSA, the drug-resistant staph bacterium, spreads through Alberta's hospitals, including the carriers nobody flags at the door. Patients can carry the germ without symptoms, and arrivals quietly seed wards. Their 2026 study built a Bayesian compartment model of 106 hospitals, splitting patients by where the germ was acquired and whether it merely colonised or infected. Data from Edmonton, Calgary, and rural areas fitted the model, and simulations varied how many carriers slip in per thousand admissions.
Infected patients passed the germ to susceptible contacts more readily than carriers did. Calgary's hospitals showed the highest transmission, rural hospitals sat in the middle, and Edmonton's ran lowest, though the uncertainty ranges overlapped. Assuming more hidden carriers nudged transmission rates up slightly. The authors say the model gives teams a map of where spread pressure concentrates, and a way to test screening policies before paying for them.
