VIDEO: There is a small group of organizations in the United States who can say they have a stamp of approval from the World Health Organization (WHO).
Joining that circle could be Heart to Heart International, a Lenexa-based nonprofit. They respond and send aid to areas of disaster.
Whether it's a hurricane, an earthquake or war, their full-scale mobile health facility would have to be ready to roll within 48 hours for the WHO's approval.
It must also be self-sufficient and able to help 50 patients.
"If you can imagine surviving a disaster and feeling super vulnerable and needing medical care and the team is not from your community, maybe doesn’t speak the same language as you, it takes a while to overcome that obstacle of building trust," said Dr. Agustina Boehringer, chief medical officer for Heart to Heart International.
