After decades of progress against one of the most contagious human viruses, the world is seeing measles stage a slow, steady comeback.

The World Health Organization and the CDC say in a new report that there were nearly 10 million cases of measles last year, with outbreaks on every continent.

An estimated 140,000 people died from measles in 2018, WHO says, up from an all-time low of 90,000 in 2016.

David Pierce was never someone who sat around watching life go by. He worked as a chef and had a catering business on the side. He sang in his church choir and did community theater, where he met his wife.

Then, in his mid-50s, doctors removed part of Pierce's foot, a complication of diabetes.

"My health just went, kind of really downhill. It really took a turn for the worse," says Pierce, sitting at his dining room table in his tidy home in Apalachin, N.Y. "I couldn't maintain even a part-time schedule."
