Cameroon: Poor sanitation causes cholera outbreak in Douala

More than 500 cases of cholera have been reported over the past seven weeks in Douala, the largest city in Cameroon, and at least 13 people have died of the disease, according to government statistics. However, health workers told IRIN that the real cholera infection rate in the heavily polluted port city of 2.5 million people could be much higher than official figures suggest.
