Serbian health officials say two more cases of swine flu have been diagnosed at the World University Games.
Officials said Monday the two unidentified athletes are from Argentina and Uganda. Last week, an Australian swimmer was diagnosed with the virus.
Several people who were in contact with the infected athletes are being isolated to prevent the spread of the disease at the multidisciplinary games, which are attended by about 8,500 athletes and officials.
Since last month, 21 swine flu cases have been recorded in Serbia.
