Cholera outbreaks began around the same time at the beginning of 2012 in Sierra Leone and Guinea.
On 16 Aug 2012, the government of Sierra Leone declared the outbreak a national emergency after 176 deaths and 10,800 cases had been reported since January (AFP, 16 Aug 2012). By 30 Aug, the numbers had risen to 13,934 reported cases and 232 deaths (WHO, 30 Aug 2012).
In Guinea, the outbreak had killed 82 people and affected more than 2,000 by 19 Aug 2012 (AFP, 19 Aug 2012).
By 16 Sep, the epidemic had eased, with both countries reporting decreasing number of new cases for three weeks in a row (OCHA, 17 Sep 2012).
The outbreak in Sierra Leone had declined from a high of more than 2,000 cases per week at the peak of the outbreak in August, down to 16 cases at the beginning of 2013. Although this is a significant decline, cases are still being reported in four districts, requiring ongoing prevention and control efforts to ensure the outbreak does not spread further.
