Figure 4. Viral survival in water at 35°C.
Viral persistence of A/Paris/2590/2009(H1N1)v (—) and A/New Caledonia/20/99 (H1N1) (····) in water at 35°C. Linear regression for persistence of H1N1pdm in water at 0 ppt (A), 5 ppt (B), and 35 ppt (C) are represented. TCID50 values corresponded to the mean values of the titres made in parallel from the 2 aliquots of water samples.
