Laboratory tests for influenza and the respiratory syncytial virus may be used as a proxy for associated hospitalizations in Canada

Show abstract
In Canada, the national number of hospital admissions associated with influenza and respiratory syncytial virus (RSV) is usually available about three months after admission. This delay hampers real-time analysis involving hospitalization data, like, for example, epidemic forecasting. Here, using a mixed-effects model on 15 years of data covering about 70% of the Canadian population, we show that these hospitalizations can be approximated using the number of laboratory tests positive for influenza A and RSV, a data stream publicly reported much more rapidly, about two weeks after symptoms onset.

"Similar papers" are the closest papers from that journal in the model's embedding space. They show what the match is built on, but the ranking comes mostly from a classifier over the whole training set, not from these examples alone.
