More than 13,000 families have arrived in Kanyaruchinya, north of Goma, to escape violence in their villages.
Kibombo Kalinunda brought his wife and eight children to the camp when M23 rebels, who are fighting Democratic Republic of Congo (DRC) troops, attacked their village.
The displaced famillies have endured harsh conditions, with little food and water.
Kalinunda has lost three children due to a cholera outbreak at the camp.
"We just are just living like this. We are either going to die of hunger, or the rain," said Kalinunda.
"We don't have any way of helping ourselves. Going home isn't an option, so now we live like wild animals."
To manage the cholera, the medical charity Doctors Without Borders has set up a hospital, but they are already overwhelmed with the volume of people needing treatment.
