The WHO said this about coronavirus in their Bulletin published 27 February 2020:

“…. the COVID-19 virus is transmitted between people through close contact and droplets, NOT BY AIRBORNE TRANSMISSION. The people most at risk of infection are those who are in close contact with a COVID-19 patient or who care for COVID-19 patients.”

They went on to say that you should only wear a medical mask if you have signs of respiratory symptoms. and: “The current global stockpile of PPE is insufficient, particularly for medical masks……… the current demand for respirators and masks cannot be met, especially if the widespread, inappropriate use of PPE continues.”

The WHO recommended the general public NOT to wear a mask as it was an inappropriate use of scarce Personal Protection Equipment.

Even in their 6 April Bulletin they continued to say: “However, there is currently no evidence that wearing a mask (whether medical or other types) by healthy persons in the wider community setting, including universal community masking, can prevent them from infection with respiratory viruses, including COVID-19.”

The WHO was saying as late as the end of February that coronavirus was NOT transmitted in the air.

But a month earlier on 23 January 2020, the very worried government of China imposed a lockdown in Wuhan (a city of 11 million people) and other cities in Hubei … The WHO, called it “unprecedented in public health history”.

The Chinese government also arrested doctors and citizen journalists to prevent the facts getting out.

The Chinese government concealed the truth from the WHO and the rest of the world. Over ONE MILLION people worldwide so far have died needlessly from this virus.

 A Biden government won’t hold China to account unless there is a public outcry.
