One week after the earthquake, delivery of food, water and medicine has picked up.

US officials, who had previously refused to make airdrops in case they led to fighting for food on the ground, have changed tack due to congestion at airports hampering food deliveries.

The number of the dead is still unknown. Haitian officials estimate between 100,000 - 200,000 people were killed.

Tens of thousands of Haitian children have been orphaned by the quake, aid groups say.

Some of those have left Haiti bound for the US where they will receive medical treatment and possibly be adopted by American families.
