Bhirao, 5, takes care of her baby brother while she sits on ground along with livestock after fleeing from flood water with her family in Sukkur at Pakistan's Sindh province August 13, 2010. Disease outbreaks pose new risks to victims of Pakistan's worst floods in decades, aid agencies said on Friday, potentially hindering already complicated relief efforts. The floods, triggered by torrential monsoon downpours, have engulfed Pakistan's Indus river basin, killing more than 1,600 people, forcing two million from their homes and disrupting the lives of about 14 million people, or 8 percent of the population.
