Obama staffer sick after Mexico trip

WASHINGTON (CNN) - A government official who traveled to Mexico to support the delegation accompanying President Barack Obama later came down with flu-like symptoms, White House Press Secretary Robert Gibbs said Thursday.

It is not known if the individual - part of Energy Secretary Steven Chu's security detail - contracted the swine flu virus. The outbreak of the virus appears to have originated in Mexico.

The individual, whose name was not revealed, has since recovered, as have three members of the individual's family who later tested positive for Type A influenza. Tests are currently under way to determine if they contracted the swine flu virus, also known as 2009 H1N1.

The staffer was present at a dinner in Mexico City with President Obama, but never came within six feet of the president, Gibbs added. The individual, who was in Mexico between April 13 and 18, never traveled with the president on Air Force One.
