Title: Does spatial proximity drive norovirus transmission during outbreaks in hospitals? Document date: 2013_7_12
ID: 2rvdedui_34
Snippet: Our study focused on patients rather than staff. Our hypothesis was that symptomatic patients who vomit are most likely to contaminate the area close to them and other patients in their vicinity. Obtaining data on staff movements is much more complicated and would only really be practical in a detailed prospective study. The importance of spatial proximity in propagating transmission is consistent with other recent studies [15, 21] . One study wh.....
Document: Our study focused on patients rather than staff. Our hypothesis was that symptomatic patients who vomit are most likely to contaminate the area close to them and other patients in their vicinity. Obtaining data on staff movements is much more complicated and would only really be practical in a detailed prospective study. The importance of spatial proximity in propagating transmission is consistent with other recent studies [15, 21] . One study which used similar methods to calculate the infection trees [15] suggests that symptomatic individuals are likely to be the drivers of outbreaks of norovirus in hospital settings. Furthermore, the effective reproductive number was significantly higher for symptomatic patients compared to that for symptomatic staff.
