Cholera spread tracked at household level

For the first time, the transmission of cholera has been tracked at the household level across Dhaka, Bangladesh, a city with a 'hyper-endemic' level of the disease. Researchers found that nearly 80 per cent of the cholera transmission in Dhaka occurred between people who shared a household. The results of the large-scale genomic study could be used by public health officials to improve cholera control strategies.
