It says Haiti lacks the basic skills, tools and equipment needed to fight a disease that is little known to Haitian health workers and citizens.
EU Humanitarian Relief Commissioner Kristalina Georgieva said Thursday that the month-old cholera epidemic has killed 1,100 people in Haiti and hospitalized more than 18,000.
She said there is a need for medical expertise, beds, epidemiological expertise, antibiotics, intravenous catheters and body bags.
Georgieva said: "This is a very difficult moment for Haiti. It is likely to get worse before it gets better."
