Haiyan is estimated to have destroyed about 70 to 80 percent of structures in its path as it tore into the coastal provinces of Leyte and Samar.
Officials say that 10,000 may have died after the devastating typhoon that hit the Philippines. As survivors assess the damage, Joseph Curry, with Catholic relief services says that victims are in desperate need of help rebuilding their homes.
