Humanitarian aid workers who gathered with colleagues in the country’s main city of Yangon to discuss the spiraling crisis warned Monday in the next two weeks food stocks will run out and at least 20,000 people will be without clean water in 10 days.

The heath situation is even more dire, they said, with almost no life-saving services such as emergency hospital referrals.
