Figure 1From: Does reservoir host mortality enhance transmission of West Nile virus?Decline over time of susceptibility according tovarious virulence scenarios. The curves represent birds' median ordered times to becoming infected, i.e. loosing susceptibility. The color range represents extreme virulence (100% mortality – red) to avirulence (no mortality – purple), as well as all intermediate virulence scenarios (90% – orange, 75% – light green, 50% – turquoise, 25% – light blue and 10% mortality – navy blue).Back to article page
