BROOKINGS - Dr. David Sack, the first person to receive the Gates

Award for Global Health and a finalist for the Nobel Prize, will speak

on campus at South Dakota State University in the Biostress Building

Auditorium at 4 p.m. Friday, Oct. 28. The title for his public talk is

"The Science of Diarrhea: Toward Controlling a Major Killing Disease."

Sack, a professor in international health and epidemiology at Johns

Hopkins Bloomberg School of Public Health in Baltimore, invented what

some regard as the miracle of 20th century medicine, oral rehydration

therapy. The groundbreaking therapy effectively treats patients using a

rehydration buffer that is given orally to combat life threatening,

infection-causing diarrhea.

Research by Sack for enteric, intestinal, infections and vaccine

development for those infections, has focused on describing the

epidemiology in travelers and developing country populations. Advancing

appropriate clinical management strategies, including antibiotics and

rehydration methods, have been a large part of his research. He served

as the director for the International Center for Diarrhea Disease in

Global Health in Bangladesh for eight years.

Weiping Zhang, associate professor of veterinary and biomedical sciences

in the Center for Infectious Disease Research and Vaccinology at SDSU,

has collaborated with Sack on some of his research.

"One of the new missions of the SDSU Veterinary and Biomedical Sciences Department is to combat human diseases and to improve both human and animal health," said Zhang. "My research program is focused on the prevention of diarrhea disease and to develop vaccines against enterotoxigenic Escherichia coli (ETEC) disease."
