The European Centre for Disease Prevention and Control (ECDC) said on Friday that many European countries are seeing an unhealthy rise in the number of measles cases. Switzerland tops this list, the agency said.
"This is very concerning ... particularly in light of the WHO (World Health Organisation) aim to rid Europe of measles by 2010 ... We're moving in the wrong direction," said Ben Duncan, a spokesman for the Stockholm-based EU agency.
Measles, also called rubeola, is a highly contagious disease characterised by high fever and the eruption of small red spots that kills about one person for every 1,000 infections.
Several European countries saw a hike in measles cases last year, and the numbers have grown further so far this year, according to European Union numbers.
During the first three months last year, just under 800 measles infections were reported across the continent. That number climbed to more than 1,300 in the first quarter this year, Duncan told AFP.
"There is a significant number of Europeans who have not vaccinated against it ... In some parts of Europe, less than 80 percent of kids are being vaccinated against the disease," he said, explaining the increase.
ECDC said very few countries in Europe had reached the 95 percent measles vaccination target necessary to prevent outbreaks and eliminate the disease.
Duncan said countries in Europe's Alpine region, led by Switzerland, were home to especially strong anti-vaccination movements.
