The World Health Organization (WHO) Director General Dr. Tedros Adhanom Ghebreyesus on Wednesday blasted U.S. President Donald Trump, telling him if he wants to have many body bags he should keep politicizing COVID-19, the respiratory disease caused by the novel coronavirus.

Dr. Ghebreyesus did not mention President Trump by name, but he warned that using a disease that has wreaked havoc all over the world is a waste of time. The WHO boss said trying to politicize the virus is like playing with fire.

He called on the world leaders to use other means to cheap “political points” and not a disease that is ravaging the planet.

He said the world should focus on the issue at hand, defeating the virus, and “quarantine politics”, saying “let’s fight like hell” to defeat this virus. He said failure to do that, the worst may be yet to come.
