A top Chinese expert on the spread of the corona virus in the world fears that if the virus does not stop spreading, it could infect 60 to 70 percent of the world’s population, or about 4 billion people. “People around the world need to be vaccinated against corona on a large scale,” said Jong Nanshan, an expert on respiratory diseases in China.
The virus could remain unchanged until spring next year. He said it would take one to two years to deliver the corona vaccine to people around the world and would require global cooperation. The Chinese expert’s prediction comes at a time when the corona virus has infected 30 million people and killed 9.50 million people worldwide.
