Health workers battle cholera outbreak at world's largest refugee complex UN Refugee Agency (UNHCR) reports that efforts continue in the fight against a deadly cholera outbreak at the world's largest refugee camp, Dadaab in Kenya. UNHCR and its partners have been working with officials in Kenya to stamp out the disease at the Dadaab refugee complex in the north-east of the country, home to more than 340,000 people. Cholera is a water-borne bacterial illness that causes fever, vomiting and watery diarrhea. It is often fatal. UNHCR says 10 people have died and about 1,000 others have become sick as a result of the outbreak, which began in mid-November. The agency says the flare-up is linked to rains brought on by the El NiƱo phenomenon which has affected weather patterns across the globe. SOURCE: UN Radio
