A small group of Argentines pelted a bus from Chile with rocks and sticks over fears that a man on board was bringing swine flu into their town, authorities said on Friday.
Angered over radio reports that one of the 43 passengers exhibited flu symptoms at a border checkpoint, residents of Godoy Cruz in Mendoza province surrounded the bus at a hospital late Thursday, health official Pedro Masman told Todo Noticias television.
"Get them out of here!" and "Take them somewhere else," they yelled while throwing stones at the vehicle. Police fired rubber bullets at the group, which numbered more than a dozen. One protester and six officers suffered minor injuries, the official Telam news agency reported.
The 29-year-old Chilean man was tested and determined not to be infected with swine flu, Mendoza hospital director Maria Bresca said.
Argentine Health Minister Graciela Ocana reported a second case of the virus on Friday, confirming that a woman who'd traveled to the United States three weeks before presenting symptoms had tested positive.
Neighboring Chile has confirmed 24 cases - leading Argentine officials to screen travelers for viral symptoms and causing concern among border-town residents.
