According to the World Health Organization, an estimated 10.3 million people were infected with measles and 107,500 died. Most were unvaccinated people or children younger than five. Cases were most common in parts of Africa, the Middle East and Asia where incomes are low and health services insufficient.

The United States has recorded its first measles-related death in over a decade, as a growing number of cases sweeps across the country, with Texas emerging as the epicentre of the outbreak, officials said.
