Volume 485: debated on Wednesday 10 December 2008

To ask the Secretary of State for Health how many nosocomial cases of small round-structured viruses there were in each strategic health authority area in each of the last five years. (241054)

The information requested is not available. The best data are from the Health Protection Agency's (HPA) voluntary reporting system for outbreaks. This is not comprehensive but identifies where hospital outbreaks occur and the cases associated with these. Data for the last five years are shown in the following table by HPA region.

Note:

The number of laboratory reports received underestimates the true number of affected individuals as specimens are not taken from everyone affected during outbreaks of norovirus (clinical diagnoses are often made once it is known that the virus is in circulation).
