Measles has to reach Madagascar and has caused more than 900 people deaths says The World Health Organization.
There are more than 68,000 types of disease, in which 553 were confirmed dead and while 373 are suspected from measles since the outbreak began in September said WHO.
This is caused by the low immunization rate for measles across the island nation throughout many years, says the spokesman Tarik Jasarevic. The vaccination rate is estimated to be less than 60%, according to figures from WHO and UNICEF figure, he said.
The nationwide campaign has been launched by Madagascar to try to bring the outbreak under control, through mass vaccination campaign and surveillance.
