Seven cases of cholera have been diagnosed in Iraq in the past two days, including one fatality, a senior health official said on Sunday, according to Reuters. Scarcity of water during Iraq's scorching summer forces more people to drink water from unsafe sources, the official said. More than 4,000 cases of cholera, which can kill victims with sudden severe diarrhoea, were diagnosed in Iraq last year. Iraq's General Director of Public Health Ihsan Jaafar said as long as there was scarcity of water, cholera would remain a problem. A boy died in southern Maysan province, five of the infected are from the Abu Ghraib district of western Baghdad and one from Rusafa in the east of the city. Last year's outbreak, in which at least 24 died, was mostly in the northern cities of Kirkuk and Sulaimaniya. Cholera is characterised in its most severe form by a sudden onset of acute watery diarrhoea that can cause death by severe dehydration and kidney failure within hours. It is mainly transmitted through contaminated water and food. Water and sewage treatment is a perennial challenge in Iraq, where an overhaul of decrepit public works has been hindered by years of war and neglect. Jaafar said the Health Ministry was trying to control cholera's spread by early diagnosis of infection, distributing water sterilisation tablets and through a public awareness campaign.
