Figures for 2009 Swine Flu cases in the UK (HPA modelling) for weeks 28 onward (week ending 12th July onward) sourced from HPA press release archive[1] archive copy at the Wayback Machine beginning with the 16th July press release, and previous figures for weeks 22 to 27 (June) estimated from inspection of Fig 5 in "HPA Weekly National Influenza Report" (pdf document) for week 31.[2] archive copy at the Wayback Machine The HPA ceased the modelling estimates after week 51 (week ending 20th December).

This graph was created with the following Python/Matplotlib script:

#!/usr/bin/env python
from pylab import *
fig5=[250, 500, 1000, 2000, 10000, 20000]
flu09=fig5 + [55000, 100000, 110000, 30000, 25000, 11000, 5000, 4500, 3000, 5000, 9000,
  14000,  18000, 27000, 53000, 78000, 84000, 64000, 53000, 46000, 22000, 11000, 9000, 6000]
rc('axes',lw=2.0)
plot(range(1,1+len(flu09)), flu09, 'rD-', lw=3.0)
xticks( array(range(0,8))*4.4+1.1,['Jun','Jul','Aug','Sep','Oct','Nov','Dec'],size=18,ha='left')
yticks(size=18)
