MEXICAN POSTAL WORKER IN MASK SORTS MAIL.
Domingo Aguirre, a worker at Mexico City airport's central mail sorting
facility wears a surgical mask as he classifies recently arrived
international post October 16, 2001. Aguirre said he had bought the
mask himself to try to protect himself after the spate of anthrax
spores sent in the mail in the United States. REUTERS/Andrew Winning
