The World Health Organization just declared the novel coronavirus outbreak to be a pandemic.
The novel coronavirus outbreak is the first pandemic caused by a coronavirus, WHO Director-General Tedros Adhanom Ghebreyesus said Wednesday.
"Describing the situation as a pandemic does not change WHO’s assessment of the threat posed by this coronavirus. It doesn’t change what WHO is doing, and it doesn’t change what countries should do," he added.
Remember: CNN began calling the virus a pandemic earlier this week.
The specific criteria for a pandemic are not universally defined, but there are three general criteria: a virus that can cause illness or death; sustained person-to-person transmission of that virus; and evidence of spread throughout the world.
