Measles is now an "imminent threat" across every region in the world, according to the World Health Organization ( WHO ) and the US public health agency.
A joint report by the two health organisations said millions of children were now susceptible to measles, one of the world’s most contagious diseases, due to a fall in vaccine uptake during the pandemic.
The disease is almost entirely preventable through vaccination, but at least 95 percent vaccine coverage is necessary to prevent outbreaks.
