But it takes a long time to rebuild a city and the area around it. Just finding places to move all the broken parts of buildings was difficult. And countries promise money to help rebuild, but it takes a while to get the money, and in most disasters, only half the money that is promised is actually sent. (This doesn't count millions of dollars that people gave directly). For years many people were living in tents, wherever they could find room. And workers for the UN introduced cholera to the country in October 2010, which made many people sick and killed thousands more. The country is still recovering to this day.
