This year’s flu season has been particularly hard on Victoria’s elderly. The flu, or influenza, is a highly contagious viral infection, spread by contact with fluids from coughs and sneezes.
Statistics from The Department of Health and Human Services have revealed that 78 aged care residents have died due to the influenza virus.
This is more than twice the number of aged care residents that died during last year’s flu season, where there were 36 fatal cases.
Overall, there have been 222 respiratory outbreaks this year compared with 117 for the same period last year.
Because of the close confinement of nursing homes with shared staff and common eating/social areas, flu outbreaks are highly susceptible in aged care.
In 2015, influenza was the 12th most common cause of death, with the average victim being 88.6 years old.
One of the challenges with this year’s strain of influenza is that it has mutated in such a way that it is immune to some vaccinations. This means that even people who have been immunized are still at risk of contracting the virus.
Kanta Subbarao, director of the World Health Organisation’s Melbourne influenza research centre, told the Herald Sun that 70 per cent of cases have been the A/H3N2 strain.
There were four strains of flu in this year’s vaccine — A/H3N2, AH1 and two types of B strains.
“Even at the best of times vaccines are not as effective in the elderly as they are in young adults.”
Despite that, it is still recommended that everyone, who are able, should get the flu shot.
