Percentage of extremely severe cases [d] gives the age-class dependent probability that a case who is hospitalized (or ought to be hospitalized) dies of the disease (note that some patients die before they seek medical help and can be sent to a hospital). |

Whether a severely sick patient will survive or die does not influence his or her degree or duration of contagiousness. |

This parameter determines the height of the curve depicting the number of deaths. |
