This is part of a news from 2014 and the woman is talking about Ebola in Somalia.

From 1:55, she said, "Yes, it`s scary. Yes, it`s terrifying. Of course, it`s terrifying. But what are you going to do? Women, men, children are dying, families are being devastated. And in any other conflict situation, people take that risk and they go in. Somali during the famine, you couldn`t move for the international community, and you get to Monrovia, and you just feel the sense of loneliness and isolation and the fact that people just aren`t on the ground."

What does "you couldn`t move for the international community" mean here? Does it mean they can't seek help from the international community?

And does the last line "people just aren`t on the ground" mean people would not go outside?

Thank you for help!
