The World Health Organization recently sparked controversy when the Head of Emergencies claimed that as many as 10% of the World's 7.6 to 7.7 billion people may be already infected with the coronavirus which would translate to between 760 and 770 million people.
The number is quite controversial as it is over 20 times the current number of confirmed cases in the world according to various Coronavirus monitoring bodies.
