Brazil's Health Ministry says that more than 1,550 people have contracted measles as the country struggles to meet vaccination targets to stem the outbreak linked to neighbouring Venezuela.
The cases are concentrated in two states on Brazil's border with Venezuela. Health services have collapsed in the neighbouring country amid political turmoil. Measles started spreading in Venezuela last year after the World Health Organization declared the Americas measles-free in 2016.
Earlier this month, Brazil launched a campaign to vaccinate all children between one and five.
The campaign is scheduled to end today, but only one state has reached the goal of vaccinating 95 per cent of the target population. The ministry is encouraging local health authorities to extend their campaigns to reach the goal.
