On Saturday evening two more cases of the disease were confirmed.

Earlier, police named the second person to die in Britain's biggest outbreak of Legionnaires' disease in 10 years.

The woman, who died on Thursday night, was named as Wendy Millburn, 56, of Walney, Barrow-in-Furness.

Most of those affected are from Barrow

Doctors expect more cases to emerge over the weekend, Morecambe Bay Hospitals NHS Trust said.

The incubation period means the infection can take 10 days to show up.

Mrs Millburn, a former school cook, leaves a husband, two adult children and two grandchildren.

The first person to die in the outbreak, on 2 August, was 88-year-old great-grandfather, Richard Macaulay.

Honeymoon couple

Meanwhile, a 30-year-old woman was awaiting tests which would show if she had contracted the disease while on honeymoon in the coastal town.

Kirsty-Ann Smith, from Rochester, Kent, was admitted to hospital on Tuesday after developing symptoms of the disease.

She and her new husband Jonathan had spent most of their honeymoon in the Lake District but stopped in Barrow for one day to visit a zoo.

Possible symptoms

Only when they arrived home on 2 August did Mrs Smith begin to develop some of the possible symptoms of the killer disease and was admitted to Medway Maritime Hospital in Kent where she has undergone tests.

Hospital officials were saying it was "very unlikely" she has the disease but added that the test results would not be available until next week.

Arts centre

The total number of people in Barrow who have now been tested stands at 1,561, but overall a "steady reduction" in the number of new cases is emerging, a trust spokesman said.

A 30-year-old air-conditioning system at the council-run Forum 28 arts centre was closed down on 1 August after being blamed as the source of the outbreak.

Tests on the system found traces of the legionnella bacteria, which causes the disease, in the water treatment plant.
