Cast and crew on the set of the drama have been put on high alert after Hatcher notified show producers she had been diagnosed with the virus known as H1N1, reports TVGuideMagazine.com.
Hatcher's illness comes at a bad time for the production crew - she was due to join all of her co-stars to shoot an important Christmas episode said to involve a small plane crash.
The actress has joined a growing list of celebrity stars who have been crippled by the swine flu - Backstreet Boys singer Brian Littrell and Harry Potter actor Rupert Grint have both contracted the virus.
