The number of confirmed cases of Legionnaires disease has risen but the worst of the outbreak appears to be over, health chiefs said.
There are two new confirmed cases of the disease, taking the total to 41. They were both previously classed as "suspected" and the number of suspected cases has therefore dropped from 49 to 47.
So far one man has died, named locally as 56-year-old Robert Air, from Seafield in Edinburgh.
The Health and Safety Executive (HSE) and Edinburgh City Council are investigating the source of the outbreak in the south-west of the capital.
Of the cases being treated in hospital, 11 are in intensive care and 19 are on general wards. A total of 18 cases are being treated in the community, while 32 have been discharged from hospital. Seven cases are being treated outside the NHS Lothian area.
Health Secretary Nicola Sturgeon said: "These numbers today again offer reassurance that the worst of the outbreak is over. The increase of confirmed cases and reduction in the suspected cases is in line with our expectations. However, there is no room for complacency and we will continue to monitor the situation very closely over the coming days.
"Investigations are continuing into the source of the outbreak and the risk to the public remains low, however anyone who is concerned should continue to contact NHS 24's dedicated helpline on 0800 0858 531 or their GP."
Dr Duncan McCormick, chairman of the incident management team and Consultant in Public Health Medicine at NHS Lothian, said the numbers were in line with what they would expect at this stage in the outbreak: "It is encouraging to see that the number of patients being treated in critical care has reduced and that overall more patients are recovering and being discharged home."
On Monday a pharmaceuticals firm in the area where most of the cases originate was served with two improvement notices by the HSE. The watchdog ordered thorough cleaning of one of Macfarlan Smith's cooling towers and ordered provision of access for the same tower so it can be inspected and maintained.
Last week the watchdog served an improvement notice on North British Distillery Company in the same area. The firm was censured for failing to devise and implement a sustained, effective biocide control programme for one cooling tower on its site.
