SEOUL, May 28 (Xinhua) -- South Korea's Ministry for Health, Welfare and Family Affairs reported Thursday that three more cases of Influenza A/H1N1 have been confirmed, bringing the number of reported infections to 32 in the country.

    According to the ministry, a 41-year-old American English teacher, a 38-year-old educator and a 19-year-old Korean were confirmed to have been infected with the new flu virus.

    The English teacher and the educator worked at the same language institute, where by Wednesday 20 employees, mostly foreign instructors, had been found to be infected with the contagious disease.

    The 19-year-old Korean is being treated at a state-designated hospital since returning from overseas on Tuesday after she showed flu-like symptoms, the ministry said.

    South Korea had been considered relatively insulated from the A/H1N1 influenza virus until last week, with just four confirmed cases reported.

    The number, however, is growing sharply after a group of foreign English teachers were found to be infected in the same language institute over the weekend, raising concerns that the virus might be spreading through person-to-person contact.

    According to the latest tally by the World Health Organization,48 countries have officially reported at least 13,398 cases of influenza A/H1N1 infection, including 95 deaths. Most deaths have occurred in Mexico and the United States.
