NHSN flu data- are there long tails or multiple peaks in facilities?
Background Our nursing home flu model shows a long tail in cases due to the high turnover of short-stay patients, leading to high introduction of susceptible individuals that can sustain transmission at a low level.

Calibrating constant community importation
Investigating integration of community transmission into nursing home model of antiviral use for influenza prophylaxis Model includes a importation of cases from community by staff. We want to represent this process, without it being a focus of the model. One of the suggested ways to incldue it is as a constant low rate of infection of staff. Her...

Update: HSAs and SVI of healthcare seeking for hospitals and SNFs
COmparing the HSAs of resident homes vs. facility Can the population within a facility be well-characterized by the population within the surrounding HSA? 1. DO people go to facilities within their same HSA? 2. If they go to different HSAs, is the soocial vulnerability of the facility HSA similar to that of their home? Or, do people typically go...
