A six-year-old girl from Oxfordshire, who contracted swine flu, has now made a full recovery.

Health officials announced this morning the girl - who has not been named - responded well to anti-viral drugs after being treated at home.

The girl who is believed to be the youngest patient in Britain to be treated for the potentially dangerous virus, had recently returned from a holiday in Mexico.

It is understood that she has been at her school since returning from the country where the outbreak started.

However Dr Eamonn O’Moore, interim director and consultant in communicable disease control for Thames Valley Health Protection Unit, said health officials were not unduly concerned about fellow pupils or staff.

The school she attends, which has also not been named, will not be closed.

Swine flu has been credited with 101 deaths in Mexico.

The girl was the 15th confirmed case of swine flu in the UK — 12 of which were in England and three in Scotland.

Oxfordshire PCT has released a step-by-step guide for members of the public who have just returned from Mexico or another affected country and suspect that they may have swine flu.
