Cherie Blair, wife of former British prime minister Tony Blair, has suspected swine flu, it was revealed today.
Ms Blair has pulled out of a series of public engagements.
It is understood she was identified as likely to have the virus on Tuesday.
Mr Blair and the couple’s children have not shown any signs of being infected.
Mrs Blair has been given a course of Tamiflu, and told to rest.
The Queen's Counsel had been due to pick up an honorary degree at Liverpool’s Hope University today, and also cancelled a staff barbecue to ensure the virus was not passed on.
Mr Blair’s office refused to comment.
Health officials in Britain said today that 29 people have died after contracting the H1N1 flu.
Britain's Health Protection Agency estimated that there had been 55,000 new cases of swine flu in the last week. The majority of cases were mild.
