The risk of influenza is still high.

A 100-year anniversary of the catastrophic impact of the flu in Spain has warned that the risk of another flu pandemic is still high.

The main event of the Spanish flu occurred between October and December 1918. As in World War I, New Zealand lost half of its people in just a few months. There were 50 million deaths and 9000 deaths worldwide in New Zealand.

Professor Geoff Rice attended a ceremony marking the 100th anniversary of the worst public health disaster in Wellington last weekend.

The researcher said the risk of another flu pandemic was still high and that if a similar fatal infection hit New Zealand today, we could expect more than 30,000 deaths.

In 1918 cities like Wellington were stopped. City Hall has been changed to a temporary hospital and removed from City Hall to provide space for City Hall. The fatalities were so rapid that local mail trucks, even market chariots, were used to transport bodies to the cemetery of Karri.

The November 2018 Armistice pact contributed to the spreading spread of people gathering to celebrate the end of the long war.

The world has experienced the recent fears of bird flu in Hong Kong in 1997, and the swine flu in Mexico in 2009.

Rice said nine new cases of influenza have been reported in humans since 2000.
