David Walton, a physician working in Haiti, has cancelled his Nov. 4 talk at the University of Richmond.

Walton was scheduled to speak about his work with Partners in Health in Haiti as part of the Jepson Leadership Forum. He notified the university that he is staying in Haiti to help treat people afflicted with post-earthquake health problems, especially the recent outbreak of cholera, and others likely to occur after Hurricane Tomas.

In cancelling his appearance by e-mail, Walton said, "I'm here in Haiti and things are deteriorating rapidly." He wrote that he is seeing more patients with cholera, he expects some impact from the hurricane, and a "really catastrophic situation is about to become unimaginably worse."

His message said that medical staff are stretched to dangerously thin levels because of the cholera epidemic.

"If I leave, there will be patients [left] unattended and [with] no medical staff to care for them. I'm certain patients will die if I'm not here. ... I have never been in a situation like this before, and to be honest, Haiti has never seen anything like this before. It's truly horrific. I'm really sorry for any inconvenience this may cause."

The university is exploring the possibility of rescheduling the program. For more information, please call 804-287-6627.
