The World Health Organization on Monday said it would do everything possible to find the animal origins of coronavirus, which has taken more than 1,459,000 lives globally.

“We want to know the origin and we will do everything to know the origin,” WHO chief Tedros Adhanom Ghebreyesus said, reported AFP. 

Tedros urged critics, who have accused the agency of handing the reins of the probe to China, to stop “politicising” the issue.

The WHO chief said that the surge in cases of coronavirus in Brazil is concerning, saying the nation has to be “very, very serious.”

The fresh cases in Brazil have jumped from around 10,000 per day in early November to more than 50,000 and as the daily death rate shot up nearly ninefold in a week.

The situation in Brazil, Tedros, “is very, very worrisome.”
