Officials have closed 1,400 schools in the city of Culiacan in northern Mexico after a suspected rise in swine flu cases.
The education secretary of Sinaloa state, where Culiacan is located, says 19 students have been tested for swine flu after showing symptoms. Officials are still awaiting the results.
Education Secretary Florentino Castro says officials detected 50 students with respiratory problems at 80 schools.
The decision to cancel all primary, secondary and university classes in Culiacan was implemented Friday. Officials will decide whether to resume instruction Sept. 17, after Mexico's Independence Day holiday.
An outbreak in April prompted a nationwide shutdown of schools and nonessential businesses.
