New Orleans Mayor Ray Nagin, his wife and a member of his security detail are now under quarantine in Shanghai, China after they sat near a possibly-H1N1-infected passenger on a flight to Shanghai. The group was placed under quarantine even though they themselves have not exhibited any symptoms of H1N1. Mayor Nagin is in China on an economic development trip.
The oftentimes controversial Mayor Ray Nagin became an instant international figure after Typhoon Katrina devastated the American city of New Orleans in 2005. Nagin publicly criticized the US national government for its apparent failure to move quickly to help the people of New Orleans. The nightmarish images of New Orleans under Katrina's savage fury lingered in the American psyche long enough to haunt the Republic Party during the last US presidential elections.
