A 29-year-old woman has become the second person in Oxford to contract the swine flu virus.

The woman recently returned to the city from a trip to New York and test results received by the Health Protection Agency yesterday showed she tested positive for the influenza A (H1N1) virus.

The woman has been treated with anti-viral drugs and is said to be making a good recovery.

Family and friends of the woman — who health officials will not name — have also been given anti-viral drugs as a precaution.

So far there have been 133 confirmed cases of swine flu in the UK and 12,022 cases internationally, with 86 people dying from the virus.

Oxfordshire’s director of public heath Dr Jonathan McWilliam said: “We would like to reassure the public that levels of this disease in the country are still low. Symptoms of influenza A (H1N1) are similar to those of seasonal influenza, usually a feverish illness accompanied by one or more of cough, sore throat, headache and muscle aches.”

Oxfordshire PCT spokesman Cathryn Bullimore refused to give details of where the woman lived in Oxford or exactly when she travelled to the United States.

Ms Bullimore said it was against Health Protection Agency guidelines.

She said the woman had travelled and returned this month.

In April, a six-year-old girl who attends Sandhills Primary School contracted swine flu while on a family holiday in Mexico.

She made a full recovery.

Dr McWilliam said anyone who had flu-like symptoms and had recently returned from Mexico or the USA, or been with someone who has, was advised to stay at home, limit contact with others and call their GP or NHS Direct on 0845 4647. They should not go to a GP’s surgery or a hospital, as they may spread the germ.
