A six-year-old girl with swine flu died of septic shock following a bout of tonsilitis, it has been announced.
The post mortem results on Chloe Buckley, from from West Drayton in west London, showed the tonsilitis was caused by streptococcus A bacterium.
It is not clear to what extent swine flu contributed to Chloe's death on July 9 at St Mary's Hospital in Paddington.
Dr Simon Tanner, regional director of public health for London, said: "Following the death of six-year-old Chloe Buckley on July 9, a post mortem examination has concluded that Chloe died of septic shock as a result of a tonsilitis infection caused by the streptococcus A bacterium.
"Chloe was also found to have the swine flu H1N1 virus.
"It is not possible to say to what degree swine flu contributed to her death.
"We would once again like to extend our deepest condolences to Chloe's family at this difficult time and ask that the media respect their wishes to be allowed to come to terms with their loss in private."
A total of 29 people in the UK have died after contracting swine flu.
