Mexico Swine Flu

People wearing protective masks pay respects to Our Lady of Guadalupe as they passed over a walkway under Guadalupe’s shrine at the Basilica de Guadalupe in Mexico City, on Sunday, April 26, 2009. Mexico’s biggest Catholic church, was shut down and masses were canceled as a precaution to keep large crowds away as more deaths are believed to have been caused by the swine flu outbreak that continued to plague Mexico City.
