AN elderly woman has died in a Glasgow hospital after contracting a milder form of the flu virus.
A further four patients at Lightburn Hospital, in Carntyne, have also tested positive for Influenza B and two are giving cause for concern, according to the health board.
NHS Greater Glasgow and Clyde offered its condolences to the family of the patient.
A ward at the hospital was closed to new patients on May 23 due to an increase in the number of people who have tested positive for the virus.
The board said appropriate infection control measures were in place and there had been no new cases since these measures were implemented.
Influenza B is similar to the A strain, causing respiratory, fever and stomach symptoms, however it usually causes a milder illness, and is most seen in children.
While the A virus commonly afflicts people in the early winter, influenza B can strike at any time of the year.
 Influenza B viruses are only known to infect humans and seals.
Huma Changez, Consultant Microbiologist and Infection Control Doctor, said: “We would like to express our condolences to the family of the patient who has passed away.
“Our thoughts are with them at this difficult time.
“There is not a risk to the wider public from this isolated outbreak.”
Earlier this year, NHS Greater Glasgow and Clyde unveiled proposals to shut Lightburn Hospital as part of plans to make £60million of cuts. 
Campaigners launched a campaign to safeguard the hospital but medics questioned whether the run-down facility should be saved. 
Staff criticsed the health board for spending money on a recreational garden when the hospital had "windows so drafty that we need to put blankets on the sills to stop the cold."
The health board admitted that the hospital was not "fit for purpose" and said work was progressing to create a new day hospital facility within the main hospital.
