Why are there always new diseases in the future?!
Question:
Why are there always new diseases in the future?
Answers:
It's partly because germs and virii are able to adapt quickly, so when we kill one kind another kind threatens us.
And it's also partly that existing germs adapt to become tolerant to antibiotics, so we're always needing to develop new generations of antibiotics. Some scientists say we are abusing antibiotics, using them where we don't need them, so the whole family of drugs is becoming less useful.
