The World Health Organization has issued a warning over a significant global rise in measles cases, attributing the surge to declining immunisation rates following pandemic-era disruptions to routine vaccination programmes.

Officials reported outbreaks across multiple regions, with the steepest increases in areas where first-dose coverage has fallen below the 95% threshold needed for herd immunity.

Health authorities are urging catch-up vaccination campaigns, noting that measles is among the most contagious human viruses and can cause severe complications in young children.
