About 800,000 Rohingyas are now living in refugee settlements in Bangladesh, and 589,000 of them are in the country's Cox's Bazar since they began to flee from Myanmar on August 25.
According to separate reports filed by the Daily Star and the Dhaka Tribune, a majority of these refugees are being exposed to desperate living conditions and waterborne diseases.
Both papers quoted Unicef Executive Director Anthony Lake, as saying in a statement on Friday that adults and children urgently need food, safe water, sanitation and vaccination to protect themselves from diseases that thrive in emergencies.
On children, he said, "They need education, counselling and hope."
Edouard Beigbeder, Unicef representative in Bangladesh, was quoted by the Daily Star, as saying, "The refugees are still coming, but already we can see the appalling dangers that the children are facing. Living in the open, with food, safe water and sanitation in desperately short supply, the risk of waterborne and other diseases is palpable."
The International Organisation for Migration (IOM) has, according to the Daily Star estimated that more than half of the new arrivals are women and girls.
