What is wrong with Shug Avery when she arrives at Celine and Mr.____ house?

From the text:

"Shug Avery sick and nobody in this town want to take the Queen Honeybee in. Her mammy say She told her so. Her pappy say, Tramp. A woman at church say she dying— maybe two berkulosis or some kind of nasty woman disease."

"Ain’t nothing wrong with Shug Avery. She just sick. Sicker than anybody I ever seen. She sicker than my mama was when she die. But she more evil than my mama and that keep her alive."
