"The immediate survival needs of families in flood-affected countries are enormous," said Rudy von Bernuth, who heads Save the Children's emergency response operations. "Millions of people have lost everything. They are living in makeshift shelters surrounded by myriad environmental dangers - and the monsoon season isn't over yet. Children will be in a very difficult situation for months as their families and countries try to recover."
