The gene that causes cystic fibrosis may persist in human populations because, although two copies of it kill, having just one copy protects against tuberculosis, researchers say.
If anti-TB drugs are going to lose their effectiveness, maybe it's better in the long run that it's happening before we lose this genetic protection. Hopefully, they will discover more effective treatment, but of course, since microbes reproduce much faster than we do, they have an advantage.
