WHO launches strategy to fight 'inevitable' flu pandemics

The World Health Organization on Monday launched a strategy to protect people worldwide over the next decade against the threat of influenza, warning that new pandemics are "inevitable".

Influenza epidemics, largely seasonal, affect around one billion people and kill hundreds of thousands annually, according to WHO, which describes it as one of the world's greatest public health challenges.

WHO's new strategy, for 2019 through 2030, aims to prevent seasonal influenza, control the virus's spread from animals to humans and prepare for the next pandemic, WHO said.

"The threat of pandemic influenza is ever-present," WHO chief Tedros Adhanom Ghebreyesus said in a statement.

The world has suffered through a number of devastating influenzas pandemics, including the Spanish Flu, which in 1918 killed tens of millions of people globally.

Three pandemics have occurred since -- in 1957, 1968 and in 2009 -- when the H1N1 swine flue pandemic claimed around 18,500 lives in 214 countries.

"Another influenza pandemic is inevitable," the UN health agency said, adding that "in this interconnected world, the question is not if we will have another pandemic, but when."
