ST. MARC, Haiti — At least 135 people have died in a suspected cholera outbreak, and aid groups are rushing in medicine and other supplies today to combat Haiti's deadliest health problem since its devastating earthquake.

The outbreak in the rural Artibonite region, which hosts thousands of quake refugees, appeared to confirm relief groups' fears about sanitation for homeless survivors living in tarp cities and other squalid settlements.

"We have been afraid of this since the earthquake," said Robin Mahfood, president of Food for the Poor, which was preparing to fly in donations of antibiotics, dehydration salts and other supplies.

Many of the sick have converged on St. Nicholas hospital in the seaside city of St. Marc, where hundreds of dehydrated patients lay on blankets in a parking lot with IVs in their arms as they waited for treatment.

Catherine Huck, deputy country director for the U.N. Office for the Coordination of Humanitarian Affairs, said the Caribbean nation's health ministry had recorded 135 deaths and more than 1,000 infected people.
