I agree, halfadime, that the constant illnesses are annoying and then some. People usually suggest that you feed characters the organic food, make sure they exercise and sleep, give them vitamins and the hand sanitizer. Still, there seems to be no way to avoid the sickness. You've probably had the same experience I've had, with 4 out of 5 family members sick at the same time. Others have one illness after another. Just the way they made the game, unfortunately.
