“The threat of pandemic influenza is ever-present,” said WHO Director-General Dr. Tedros Adhanom Ghebreyesus in a press release. “The ongoing risk of a new influenza virus transmitting from animals to humans and potentially causing a pandemic is real.” 

“The question is not if we will have another pandemic … but when.”
