The death toll from Haiti’s cholera outbreak has jumped to 800. The U.S. Centers for Disease Control and Prevention says some 160 deaths have been recorded this week—more than half coming in the past 24 hours. The number of infections has also grown to 11,000. There are fears the disease could rapidly spread through the teeming camps for earthquake survivors around the capital Port-au-Prince. On Thursday, hundreds of residents demonstrated in the Port-au-Prince neighborhood of Cité Soleil to protest the response to the outbreak. A nurse in Cité Soleil said the number of infections is growing by the day.

Virgine Gauder: “The contaminations really increase every day like this. And now the concentration of the patients is in the slums, but today we saw already some patients outside the slums. Then we don’t know where we are going, but it increases every day, every day.”
