First medical emergency????

So Edward Walker built this village in the late 70’s, which means around 25 years have passed since then. Certainly enough time for the original villagers to bear and raise children to adulthood. During this 25 years, there were no other medical emergencies that required modern treatment??? No accidents, no heart attacks, no problems with child birth, no broken bones, no serious wounds, no childhood diseases… nothing? After more than 2 decades, the first serious medical problem is Lucius getting stabbed? That’s a little hard to believe.
