Even though the WHO has not, yet, declared this outbreak a pandemic,
(Why won't the WHO officially declare a coronavirus pandemic?), as of
2/26, they did say this.
"The global spread of covid-19 seems to have exploded in recent days,
with outbreaks revealed in Iran and Italy and a massive increase in cases
in South Korea. Tedros Ghebreyesus, director-general of the World Health
Organization, has warned that such cases “show that the window of
opportunity we have for containing this virus is narrowing”.
In fact, it may already have shut. On 21 February, epidemiologists warned
that we are failing to detect two-thirds of infected people travelling globally,
“potentially resulting in multiple chains of as-yet undetected human-to-human
transmission outside mainland China”. Some of those chains have now been
detected, and, ominously, many cases can’t be traced to their source."
