Update: Member of Obama Delegation to Mexico Tests Positive for Swine Flu, Along with his Son and Wife

The White House has issued a health advisory outlining "protective measures" for anyone who traveled on President Barack Obama’s trip to Mexico after a member of the U.S. delegation came down with flu-like symptoms – and tests on his family showed they’re probably infected with the swine flu.

The individual – an advance security staffer for Energy Secretary Steven Chu –appears to have spread the flu to his wife, son and nephew. All three have tested probable for swine flu, White House Press Secretary Robert Gibbs said Thursday.

Gibbs, who did not name the security aide, said he did not work closely with Obama, didn’t fly on Air Force One and is back at work at the Energy Department.
