Time running out to prepare for flu season

People are being urged to ensure they've had their vaccination with the 'flu season expected to hit in Western Australia within weeks.

Health Department data shows 20 confirmed cases of 'flu last week, with cases increasing in the eastern states.

'Flu expert UWA Associate Professor Chris Blyth said the virus traditionally moves from the east to the west coast within a few weeks.

"For those people who have forgotten to get their 'flu shot, it's important that they make this a priority now if they want to be protected before the 'flu season really hits," Dr Blyth said.

"The vaccine usually takes around two weeks to provide good protection, and this is particularly important for those most at risk, such as the elderly, children under 5 and people with chronic illness."

An infectious diseases researcher with The Kids for Child Health Research, Dr Blyth said there had been an encouraging response from parents of young children.

"We've had almost double the number of young children vaccinated against 'flu this year compared with last year," he said.

"With our new monitoring program in place, we can confidently say there has been no unexpected reaction to this year's vaccine."

Dr Blyth said there were no indication of the likely severity of this 'flu season and that the best preparation to avoid severe illness and pressure on hospitals was vaccination.
