BUENOS AIRES, Feb. 13 (Xinhua) -- The Argentine health authorities on Tuesday reported 13 new cases of dengue fever in Formosa province, north of the capital Buenos Aires.

    None of those infected were in danger of dying, the authorities said, adding the new cases were classic dengue instead of the more deadly hemorrhagic dengue.

    "Those suffering from the disease had traveled to Paraguay where dengue is prevalent," the source said.

    Formosa, some 1,850 km north of Buenos Aires, borders Paraguay and 6,500 cases of dengue have been reported there in recent weeks.

    Anibal Gomez, Formosa's head of human development, called on residents not to travel to Paraguay, "unless it is essential and inevitable."

    Moreover, Formosa authorities have set up spraying vans in Clorinda, the village bordering Paraguay, and health department assessors are going from house to house to remove stagnant water containers which provide a breeding place for the Aedes Aegypti mosquitoes that spread dengue.
