British health officials on Thursday confirmed seven new cases of swine flu - including the first in Northern Ireland - bringing the country's total to 78. Six people living in England were determined to have the virus, the Health Protection Agency said. Of those cases, three children and two adults live in London. The sixth case is an adult living in eastern England, while the seventh man is the new Northern Ireland case. The agency said four of the new cases are linked to other people with the virus. The three others are people who had traveled to Mexico. No one in Britain has died of the flu, and the Health Department has said all cases so far in the country had been mild.
