Since the morning of November 28, Médecins Sans Frontières teams have been carrying out non-food items distributions with helicopter transport to bring assistance to isolated populations due to the recent floods that have affected the region over the last few weeks. After two days of air assessment over the region most affected by the recent heavy rains, MSF teams managed to identify six villages situated northwest of Dadaab, a small town surrounded by refugee camps that accommodate up to 140,000 mostly Somali refugees. While these refugees have been severely affected by the floods themselves, some Kenyan villages located around Dadaab have been completely isolated and cut off from the rest of the country and without any possibility to receive supplies by land. Two MSF chartered helicopters have been flying in rotations since November 28th out of Dadaab to carry relief supplies including several thousands of mosquito nets, dozens of rolls of plastic sheeting, fuel supplies for generator powered water pumps and medical supplies, specifically Oral Re-hydration Salts (ORS) to the six identified villages of Gurufa, Baraki, Dertu, Alikune, Shantabaq and Kumahamthu. These villages, surrounded by water and with an estimated population of 40,000 people, have faced a massive mosquito presence since the flooding began and the most vulnerable in the villages are struggling to protect themselves from the insect bites. In addition, numerous houses have been damaged by the heavy rains that show no sign of ending. Numerous houses have been destroyed and many heads of cattle have been lost in the floods. Food reserves will soon be exhausted and without a rapid relief assistance, most of these populations will find themselves incapable of feeding the neediest. MSF teams have been present in the region of Dadaab since the begining of October 2006 assessing the needs of Somali refugee populations gathered alongside the border with north-east Kenya.
