VIDEO: Measles now an imminent global threat

(NBC) - The World Health Organization and the U.S. Centers for Disease Control say "measles is an imminent threat in every region of the world."

There were about 9 million cases resulting in 128,000 deaths globally last year.

Measles immunizations have dropped significantly since the coronavirus pandemic began, resulting in nearly 40 million children missing a vaccine dose last year. 

Measles is making a comeback and it's worrying health experts.

Much of that can be traced back to a major drop off in measles immunizations, weak disease surveillance, and delayed response plans during the coronavirus pandemic.

In addition, there are ongoing outbreaks of the disease in more than 20 countries around the world.
