Cholera outbreaks have killed at least 13 people in southwest Haiti in the wake of Hurricane Matthew, government officials say, voicing concern that the disease is spreading.
Six people died of cholera in a hospital in the southern town of Randel, while another seven died in the western coastal town of Anse-dAinault, the officials said, likely as flood waters mixed with sewage.
Cholera causes severe diarrhoea and can kill within hours if untreated. It is spread through contaminated water and has a short incubation period, which leads to rapid outbreaks.
Hurricane Matthew left almost 900 people dead in Haiti and caused major flooding and loss of livestock.
