With a constant decline in influenza-like-illness Waikato public health director Dr Anita Bell has declared the winter influenza season over.

While still circulating in New Zealand, the number of influenza cases the Waikato District Health Board is seeing in the region and nationally has decreased considerably over the last few weeks.

Under board's vaccination policy the end of influenza season also means staff who are not vaccinated are no longer required to wear masks in patient care locations.

Despite the influenza vaccine no longer been available and the season declared as over, Dr Bell says people still need to be aware of the signs and symptoms of influenza.

'It is important that people are still aware of the signs and symptoms of Influenza and see medical advice if required,” adds Dr Bell.

Influenza is a potentially serious viral infection that's much worse than a cold. Although some of the symptoms are the same, influenza is usually much more severe.

Dr Bell says it will affect up to one in five Kiwis every year and annually there are approximately 400 deaths related to influenza infection.

'Influenza can be severe enough to require hospital treatment, particularly in the very young, elderly, and in people who already have health problems.”

The virus spreads easily and hand-hygiene and cough etiquette are effective ways to reduce the spread, but the vaccine remains the most proven way to ward of the flu.

Dr Bell says if you feel unwell there are several ways that you can help reduce the spread of the virus.

This includes staying at home, covering your cough or sneeze using disposable tissues, and regularly washing your hands thoroughly with soap and hot water, then drying your hands with a clean dry towel or paper towel.

If you want to receive the influenza vaccine contact your GP or local medical centre.
