Doctors Without Borders has launched a call for nurses in Haiti as the cholera epidemic further stretches its medical personnel.

According to organization's director of human resources, Barbara Ceccarelli, the situation is urgent because the epidemic is not yet under control.

While the disease appears to be stabalizing in certain areas, it continues to spread rapidly in others.

Doctors Without Borders first hopes to increase its staff in Haiti, but also replace some on-site teams.

Workers fatigue quickly due to difficult operating and living conditions.

Ceccarelli said staff members often work more than 10 hours a day, enduring extremely erratic schedules.

The volume of work is crucial because in addition to caring for patients, nurses must also educate the public to avoid the spread of the disease.

Doctors Without Borders is seeking nurses and doctors who can commit to working in Haiti for a minimum of six weeks.

Ideally, candidates should have experience in a developing country.

The Haitian government estimates that cholera has claimed the lives of more than 1,800 people so far.
