Miguel Octavio has a graph of the SARS growth. Despite what he says, the infected population is not growing at a constant rate, though the exponential rate has slowed since a month ago. Frighteningly, the death rate (per infection) is increasing. It would be interesting to fit a logistic to these data and try and predict where they’ll level off.
He says the graph automatically updates from the daily WHO data, so it should be interesting to watch.
