According to Acting Director of Public Health, Dr Stewart Jessamine, after two mild years, in 2013 and 2014, this is much more like an average flu season,some parts of the country may be experiencing higher rates than others, including variation between the A strain and B strain.
“Obviously it is possible the season has yet to peak, although the rate of growth in cases did ease somewhat in the last week. Weekly monitoring means we can soon pick up any change in the situation.” Dr Stewart Jessamine said.
“The symptoms experienced are the same for either strain. Influenza is a serious virus and can be life-threatening, especially for people who already have existing serious health conditions.” she added.IMAGE/www.colourbox.com
