Rep. Greg Walden (R-Ore.) announced on Tuesday that he has been diagnosed with a "likely" case of swine flu, or H1N1, making him the first lawmaker known to have contracted the illness.

Walden made the announcement using his official House Twitter account, "Just diagnosed with likely H1N1. Ugh. Off to seclusion for awhile."

Andrew Whelan, a spokesman for Walden, confirmed that the congressman received the diagnosis and that he tweeted the message himself. Whelan added that he is at his home in Washington resting.


"He felt pretty good this morning but felt worse as the day progressed so he went to the doctor this afternoon to get checked out. Now he is at home following doctor's orders and taking all the necessary precautions," Whelan said in an e-mail.

He did not specify the treatments Walden received, but the Centers for Disease Control (CDC) says that most patients only require rest and limited contact with others. Some patients may be prescribed antiviral medication to combat the illness.

Meanwhile, the Office of the Attending Physician is scheduled to get its first shipment of H1N1 vaccine on Wednesday, said the Senate Sergeant at Arms Terry Gainer.

Officials are planning to administer the vaccine in accordance with the recommendations given by the CDC, which stipulates that priority be given to pregant women, small children, and people with pre-existing illnesses.

Yesterday, The Hill reported that 10 House pages were treated for flu-like symptoms in order to prevent an outbreak of the sometimes deadly disease.

On Monday, the Chicago Sun-Times reported that Rep. Melissa Bean's (D-Ill.) 16-year-old daughter was diagnosed with the H1N1 virus, causing her to cancel a swine-flu prevention event in a Chicago suburb.
