As many as 35,000 people from 62 countries are in New Orleans this week to attend the annual Conference and Exhibition of the Healthcare Information & Management Systems Society (HIMSS).

The conference began Sunday and runs through Thursday.

"They're gonna take up just about every one of our 38,000 hotel rooms in New Orleans, and they're gonna use every square inch of the Morial Convention Center," says Convention and Visitors Bureau spokesperson Kelly Schulz.

HIMSS was one of the first mega conventions to return to New Orleans after Katrina. Schulz says HIMSS is a very prominent group made up of professionals involved in healthcare delivery through technology.

The conference will feature a different keynote speaker each day, including former President Bill Clinton, who is scheduled to speak on Wednesday from 1pm to 2:15pm.

The closing keynote from 12:30pm to 2pm on Thursday will feature a debate between political consultant James Carville and Fox News contributor Karl Rove. According to the HIMSS website, they'll debate politics, economics, healthcare reform and other key initiatives affecting the country.

"New Orleanians will see HIMSS delegates I'm sure throughout the city over the course of the next several days, and I would say do what you always do, which is to be nice, be hospitable, tell them 'thank you for coming to New Orleans'," Schulz said.
