An initial trickle of refugees has fast become a flood. More Haitians are fleeing the capital now that at any time in the last week, fearful of another quake and scared of what the future might bring.
A fortunate few have somewhere to flee to, but the majority of refugees have to face a reality of having no job, no house and no prospects.
The Haitian government is even providing free buses for people to leave Port-au-Prince, others use any means of transportation they can.
