Dominican authorities are monitoring the health of 300 students and 12 teachers who traveled with three Chilean women later diagnosed with swine flu.
Health Secretary Bautista Rojas says no cases of the virus have been confirmed in the Caribbean nation, and the students and faculty are not ill.
But epidemiologists are taking precautions after the women were diagnosed with swine flu soon after returning to Chile from the Dominican resort of Punta Cana.
Rojas said Tuesday they rode in a bus with the students and teachers.
The H1N1 has sickened thousands and killed more than 80 worldwide.
