CDC and WHO claim measles is “an imminent threat in every region of the world,” as it is one of the most contagious human viruses — though it is also entirely preventable through vaccination.
In 2021, a record high of nearly 40 million children missed their first or second measles vaccine dose, meaning they are either not at all or partially vaccinated against the virus.
The CDC and WHO said there were an estimated 9 million measles cases and 128,000 deaths from the virus worldwide in 2021.
