Flu on Ledom island

In Section 2.2 you encountered the Htam people on Ledom Island:

Ledom Island is inhabited by the native Htam. The island and its people was discovered in the 15th century by a group of 20 explorers. The explorers recorded that when they reached the island there were 980 Htam.

Unfortunately, the explorers all were sick with the flu when they arrived. They decided to stay for some time on the island and only to continue their travels after they’d have recovered.

The explorers infected the Htam people and all of them got the flu as well. In no time, the whole island was ill with the flu. Fortunately, no one died.

Some years ago, a group of modern-day explorers went to Ledom Island, and found evidence of the flu epidemic recorded on the wall of a cave deep in the forest. Translated from the language Relue, this text read:

Twenty days after the foreigners arrived, already 730 Htami have fallen ill to this strange sickness.

Given this new information, you can improve the model from § 2.2, and impress your history teacher even more. Up to the next section.
