It's a good thing Lisa Whelchel is a survivor.

The Survivor: Philippines contestant has West Nile virus, she revealed on Twitter Tuesday.

"I'm fine, just tired," the Facts of Life alum wrote. "Takes a year to recover. :("

Fortunately, the newly single 49-year-old actress said that she's "expecting a full recovery."

"I've been very touched by all the sweet tweets," she added.

It's unclear whether Whelchel contracted the virus while filming Survivor. According to the Center for Disease Control's website, there have been over 5,000 cases of West Nile virus in the United States in 2012.

Wishing Whelchel the best.
