Figure 3. . . Campylobacter cases by week and Musca domestica larval growth times. Campylobacter cases per day are plotted against the minimum M. domestica growth times for the 14 days before the date for weeks from January 1989 to December 1999. The time taken for M. domestica larvae to develop was based on understood growth temperatures (145 days divided by the number of degrees above 12°C, up to an optimum of 36°C) (8). The temperatures were based on a maximum temperature in 47 temperature sampling sites across England and Wales in the 2 weeks before (Appendix).
