The relief effort in Haiti is shifting to focus on helping survivors. Haitian officials plan to temporarily relocate 400,000 people living in makeshift camps, while the U.S. government repairs the Port-au-Prince harbor to ease aid flow. The relocation of homeless families is intended to prevent the spread of diseases, as the makeshift camps have no sanitation, and residents live under tends, tarps, or the open air. According to the chief of staff to President Rene Preval, the mass relocation to sites with "adequate facilities" on the outskirts of the city could start by the end of the month. Meanwhile, the U.S. Army, Navy, and Coast Guard are trying to repair the capital's only functional industrial pier, which is critical to getting aid into the country. Currently, a 15-foot wide crack runs through the dock, making it difficult to unload cargo from the mere four ships that have been able to dock since the earthquake. The pier is so damaged that the military couldn't say how long it would take to get it up and functioning. The quake killed 200,000 people, injured 250,000, and left 2 million homeless, according to the European Commission.
