Ray Nagin prepared to leave Shanghai today after four days in quarantine imposed after possible exposure to the swine flu virus. The New Orleans mayor, his wife, and a member of their security detail had been in a hotel-turned-clinic since learning that a fellow passenger on their flight from Newark had shown flu symptoms, the Times-Picayune reports.
                                    
                                    
                                
                                
                             
                            
                            
                            
                            
                            
                                
                                
                                    
                                        "We are departing Shanghai today in the best of health and spirits," Nagin said in a statement.
