This graphic below displays the relative severity of A/H1N1 in the major infected countries. Data has been adjusted for population size, so that infection in large and small countries can be compared easily.

Case Fatality Rate - (Deaths / Cases)

20 August 2009 - "To date, the CFR attributable to the current H1N1 pandemic has been estimated at around 0.4%, based on surveillance data from Mexico and mathematical modelling [7]. This CFR is higher than that of average seasonal influenza but remains of the same order of magnitude. Whether this will change before the expected epidemic peak in the northern hemisphere in the autumn is unknown." Institut de Veille Sanitaire, France

Interpreting the graphic below

The tail of each plot begins at the position a week ago, and the head and name label are at the latest position. The longer the tail, the greater the change over the week. A move to the right shows that the rate of fatalities is growing, to the left shows it is declining. Upwards movement shows more fatalities per million of population.
