A cruise ship is due to return to the UK after several of its passengers were struck down with Legionnaire's disease.
The Black Watch had been on a seven-day cruise to Norway from Edinburgh in June when, following an outbreak of symptoms, 116 passengers were diagnosed with the disease and confined to their cabins.
Following this incident, passengers were once again struck down with the Norovirus bug during a tour of Iceland, with seven elderly Britons still being treated in hospital in Sweden for pneumonia-like symptoms.
In Surrey a fourth person has been diagnosed with suffering from Legionnaires' disease.
According to the county's Health Protection Unit (HPU) two men who remain in hospital are continuing to improve while the other two have been able to return home.
Between January and June there were 151 reported cases of the disease, an increase from 120 during the same period in 2006 and from 103 in 2005.
