KEY POINTS
  • The World Health Organization declared a global pandemic as the coronavirus rapidly spreads across the world.
  • "We're deeply concerned both by the alarming levels of spread and severity and by the alarming levels of inaction," the WHO's chief said.
  • WHO officials had been reluctant to make such a declaration.
  • Declaring a pandemic is charged with major political and economic ramifications, global health experts say.

The World Health Organization declared COVID-19 a global pandemic on Wednesday as the new coronavirus, which was unknown to world health officials just three months ago, has rapidly spread to more than 121,000 people from Asia to the Middle East, Europe and the United States.

"In the past two weeks the number of cases outside China has increased thirteenfold and the number of affected countries has tripled," WHO Director-General Dr. Tedros Adhanom Ghebreyesus said at a press conference at the organization's headquarters in Geneva. "In the days and weeks ahead, we expect to see the number of cases, the number of deaths and the number of affected countries to climb even higher."
