Dozens of Cholera Cases Reported in Haiti After Hurricane Matthew

Cholera is on the rise after the hurricane killed hundreds.

Garrett Ingoglia, a vice president of emergency response for the aid group Americares, said he has seen areas where 90 percent of the infrastructure has been destroyed. "Crops are destroyed; there is no food, not a lot of clean water," Ingoglia told ABC News.

"Cholera is a huge issue, as soon as the hurricane hit people said, 'OK, we have to be ready for cholera,' but I don’t think people expected it to come this fast or this severely," Ingoglia told ABC News.

At a badly damaged hospital in Jeremie, cholera patients were quarantined in makeshift huts and workers furiously cut plywood to make more beds. The hospital has even put two patients in one bed.

As medical staff treated dozens of patients, hospital officials told ABC News they're worried this is just the beginning of an outbreak.

Officially, the hospital has treated 55 patients for cholera, but dozens of people were waiting outdoors to be seen by doctors.

Ingoglia reported there are areas that swaths of the country that are nearly unreachable since roads have bocame "impassable" due to debris.

"All around the tip of the peninsula that area has gotten very little aid, you can’t drive there, helicopter is the only way to get there," he said. "Roads are closed. Food, water, medicine, everything has been impossible to get there."

Dr. William Schaffner, an infectious disease expert at Vanderbilt University Medical Center, said treatment is simple but that without basic supplies and medical knowledge, people can become dangerously dehydrated from the disease.

"You need resources. I think limitations that Haiti has had ... this will once again be very challenging for them," he said.
