Henry did not argue outright. Instead, he offered a new line of reasoning. "You're right. But the truly troublesome part is that this disease can spread through water and air.
"Based on the time patient zero appeared and the number of distinct infections observed since then, I calculated an R
"value of a terrifying 20. Do you need me to explain what the basic reproduction number is?
"And that figure was calculated solely from what the surveillance cameras captured. If we include what they missed, I can't say for certain whether the number would go up or down."
Jean Grey, who had been in Professor X's care since childhood, had received an excellent education. Epidemiology might not have been her specialty, but she understood it to some extent.
After hearing Henry's explanation, Jean Grey looked startled. Forgetting even her deep-seated disgust for this man, she hurriedly asked, "Really?"
Henry took back the tablet and brought up the surveillance footage he had used as his sample. The densely packed footage data, statistical figures, and entire calculation process were displayed on the tablet. "This is what I found. If you're not convinced, you can check the calculations yourself."
Jean Grey roughly snatched the tablet and studied the information on its screen. Her reaction unsettled the X-Men present. Seeing this, Cyclops asked from beside her, "Jean, is it really that bad?"
Rather than checking the calculations, Jean Grey turned her attention to the surveillance footage used as their basis, making a rough check for any misidentified cases. As she did, she said, "If you don't know much about epidemiology, let me put it this way.
"The disease with the highest basic reproduction number in history is measles, with a value of 15 to 18. It spreads through the air. Without vaccination, an ordinary
