On Tuesday mornings I get to talk on WKYB, Danville's country radio station. This was our topic today.
The global effort to eradicate disease is one of the most powerful arguments that things are getting better.
Smallpox has been wiped out. Polio is on the verge, if not already eradicated.
And now we get word that measles has been eradicated in the wild in the Western Hemisphere. There are still occasional outbreaks, but they come from outside.
There is a new danger now from the people who do not vaccinate their children, in the foolish belief that the vaccines themselves cause autism. These folks, as well as some anti-vaccine faith healing groups, endanger us all by lowering our "herd immunity."
Nonetheless, the sustained and coordinated effort of international health organizations, governments, charities, and local public health workers has achieved this great good for our part of the world.
