Haitian officials are planning to relocate 400,000 people from makeshift camps to the outskirts of Port-au-Prince. The plan is aimed at staving off the spread of disease at settlements across the city.

Homeless families have been living with no sanitation under tents, tarps or nothing at all. An estimated 2 million people were left homeless by last week's devastating earthquake.

Search and rescue teams in Haiti said there is little chance of finding more survivors in the wreckage from the earthquake.

Meanwhile, aftershocks continue to rock the country. A brief 5.9 trembler Thursday sent some earthquake survivors into the streets in the middle of the night. The shock was not as strong as several others since the 7.0 earthquake.

Geological experts said it is possible aftershocks could continue for months or even years.
