There are now nine confirmed cases of swine flu in Suffolk, the local primary care trust has revealed.
NHS Suffolk said individuals who have caught the virus have received antiviral treatment and have recovered, or are in the process of recovering.
Dr Brian Keeble, consultant in public health medicine at NHS Suffolk, said: "We are continuing work to slow the spread of the disease."
He said: "Suffolk had a good supply of anti-virals to deal with the flu."
"Suffolk is well-placed to deal with this new infection," Dr Keeble added.
People were advised to carry on with their daily lives while also taking sensible precautions to reduce their chances of contracting the virus.
Anyone who has flu-like symptoms should stay at home, limit the contact they have with other people and telephone their GP or NHS Direct.
