Number of reported deaths due to cholera
Situation and trends
Since the year 2000 through the year 2016, countries reporting to the WHO have recorded a total of 3.4 million cholera cases and 65 600 deaths. There has been an annual mean and median number of cases of 20 0691 and 177 963, respectively, with a Inter Quartile Range (IQR) of 132 016 to 229 061 (25%-75%). Mean and median annual deaths during the same period were 3858 and 3034 respectively, with an IQR of 2252 to 5044 (25-75%).
In this light, 2016 continues a recent trend over the last 4 years of below average number of cases and deaths. This is likely due more to cyclical variations in annual cholera burden than any drastic improvement in the global control of the disease. In fact, as 2016 drew to a close, there were worrying signs in some countries of continual year-round transmission in Tanzania, South Sudan, and Somalia, the latter two also suffering from growing food insecurity and prolonged conflict.
