The world needs to “wake up and consider this enemy virus as public enemy number one,” Tedros warned.

“A virus is more powerful in creating political, social and economic upheaval than any terrorist attack,” Tedros told reporters in Geneva.

“It’s the worst enemy you can imagine.”

Tedros’ alert “follows other warnings that 60 to 80 percent of the world’s population could be sickened by the virus, resulting in a massive global death toll.”
