There are only two international NGOs - MSF and Action contre la Faim - working at the makeshift camp. In MSF's first preliminary assessment in March 2009, 90 percent of the over 20,000 people at the time were deemed severely food insecure. Malnutrition and mortality rates were past emergency thresholds, and people had little access to safe drinking water, sanitation or medical care, the NGO found. But with the crackdown worsening and more Rohingya arriving, concern from aid workers is growing. They receive no assistance other than nutritional, mental health, and water and sanitation services from ACF, and medical services from MSF - making food a major issue.
