Influenza

Volume 496: debated on Wednesday 15 July 2009

To ask the Secretary of State for Health (1) how many of the cases of H1N1 flu reported to the Health Protection Agency (HPA) by 16 June 2009 were recorded by the HPA as (a) male, imported, (b) female, imported, (c) male, indigenous and (d) female, indigenous H1N1 cases; in how many such cases the patient was aged (i) under 10, (ii) 10 to 19, (iii) 20 to 29, (iv) 30 to 39, (v) 40 to 49, (vi) 50 to 59 and (vii) over 60 years; in how many such cases the HPA has recorded (A) the date of symptom onset, the date of obtaining the blood sample from which the H1N1 diagnosis was made and the date of the H1N1 case report and (B) the date of symptom onset, the date of obtaining the blood sample from which H1N1 diagnosis was made, the date of the H1N1 case report and the date on which the H1N1 antiviral prophylaxis or treatment was started; (285833)

(2) how many of the cases of H1N1 flu reported to the Health Protection Agency by 16 June 2009 were recorded as having been hospitalised by 30 June 2009; and how many such patients were aged (a) under 10, (b) 10 to 19, (c) 20 to 29, (d) 30 to 39, (e) 40 to 49, (f) 50 to 59 and (g) over 60 years;

(3) how many of the cases of H1N1 flu reported to the Health Protection Agency by 16 June 2009 were recorded as being (a) imported, (b) indigenous and (c) not assigned or not known.

The cases reported by the Health Protection Agency (HPA) are shown in the following tables.

Not all of the data requested are currently available. This is because:

testing for swine flu is based on swabs, not blood samples;

data for Scotland are not currently available for the period requested;

complete data on the commencement of antiviral treatment or prophylaxis is not available. This is because once detailed data on the first few hundred cases had been collected, the HPA stopped collecting that level of detailed information; and

verified data on hospitalisations is only available up to 16 June.
