The H1N1 example demonstrates that early fatality percentages based mainly on tested cases can be unreliable, not that a current virus is harmless. Four years after the H1N1 pandemic, researchers revised the death rate down to approximately 0.02% after developing better methods for estimating the true hidden infection count. Early scientific estimates for the H1N1 pandemic suggested a death rate of approximately 1.3%.
