Title: Does spatial proximity drive norovirus transmission during outbreaks in hospitals? Document date: 2013_7_12
ID: 2rvdedui_88
Snippet: We used more than one approach to modelling the infection trees because of the lack of data on serial interval in norovirus outbreaks. Heijne et al's method used data from child siblings at home. This was a useful starting point but is unlikely to be applicable to transmission in a hospital setting. Therefore, we derived gamma distributions for serial intervals from half a day to four days. The average incubation period for norovirus is considere.....
Document: We used more than one approach to modelling the infection trees because of the lack of data on serial interval in norovirus outbreaks. Heijne et al's method used data from child siblings at home. This was a useful starting point but is unlikely to be applicable to transmission in a hospital setting. Therefore, we derived gamma distributions for serial intervals from half a day to four days. The average incubation period for norovirus is considered to be between 24 hours to 48 hours [4, 18] . In our analysis the serial intervals of up to 2.5 days is likely to be a more appropriate time period in a hospital setting, than the analysis from Heijne et al.
