Figure 3

Trends of influenza genetic surveillance in countries under current avian influenza A(H5N1) outbreaks in humans (disease cases and deaths). Number of reported A(H5N1) hemagglutinin sequences from the 15 countries with avian influenza A(H5N1) cases and deaths (as of 25th March, 2011) [12]. G = Genetic surveillance [A(H5N1) hemagglutinin sequences]. C = Human cases of influenza A(H5N1). D = Human deaths caused by A(H5N1). Red and yellow cells denote highest and lowest values. Scale: dark-red (highest) and light-yellow (lowest).
