DHAKA, BANGLADESH - Bangladeshi health authorities said Wednesday the country's swine flu toll has risen to seven, nearly a week after the first case in a teenager who had returned from the United States.

Mahmudur Rahman, director of the Institute of Epidemiology, Disease Control and Research (IEDCR), told AFP all of the new cases had recently returned from the US and had contact with the 17-year-old who tested positive on June 18.

"Those affected are aged between two-and-a-half and 20. All are mild cases of the A(H1N1) virus and are being treated at their homes," he said.
