Figure 3 depicts a timeline beginning December 22, 2008 and ending January 22, 2009. This timeline outlines the epidemiological tracing information for IP#1 and IP#1a. December 22, 2008, 21 days before the first clinical signs of disease, marked the critical date to initiate tracing activities. The second on the outline, January 22, 2009, was the date that clinical signs of respiratory disease became present on IP#1. The third, January 15, 2009, was the critical date to complete trace-in activities. January 21, 2009, the fourth date on the timeline, was the date IP#1 and IP#1a were quarantined, and movement restrictions were applied. This was also the day IP#1 was found with positive serology for Influenza A and RT-PCR positive for H5. The final date, January 22, 2009, was the day that IP#1 and IP#1a were found with positive serology for H5 and RT-PCR for H5.
