Ten new cases of the A/H1N1 flu were confirmed on Monday in Britain by the Department of Health, bringing the total number of infected patients to 65.

A statement from the Health Department said all the 10 new cases were in England. The two cases in London included an adult and a child who were both close contacts of previously confirmed cases.

Among the four cases from East of England, an adult and a child were returning travelers. Another adult was a close contact of a previously confirmed case, while the source of infection for the fourth still remained under investigation by the Health Protection Authority.

As for the other four cases from both northwest and southeast England, two adults and one child were returning travelers, and another adult was a close contact of a previously confirmed case.

"All infections in the UK have been mild so far. Thanks to early diagnosis and treatment with antivirals, the spread of the virus is being limited and symptoms reduced," said the statement, pledging to be prepared for the possibility of a global pandemic.
