What Transmission Precautions Best Control Influenza Spread in a Hospital?

06 juin 2017

Influenza is a significant problem within hospitals, leading to extended hospital stays, excess morbidity and mortality, and economic loss. Prevention and control strategies are generally « bundled »; therefore, the individual effects of particular strategies and the value of combined strategies cannot be determined directly, making it difficult to discern the optimal strategy. To quantify the individual and joint effectiveness of several known influenza infection control measures used in general hospitals, we simulated influenza transmission at a hypothetical hospital in Ann Arbor, Michigan, during a 1-year seasonal epidemic (June 2012-June 2013), using a susceptible-exposed-infected-recovered (SEIR) compartmental model.
