Professor Ian Lipkin, an American epidemiologist known as a “virus Hunter”, said in an interview recently that the new coronavirus may have spread in humans for months or even years.
According to CNN on April 4, Lipkin, director of the center for infection and immunization at the school of public health, Columbia University, said the new coronavirus may not only come from bats in the past few months but may have entered the human body several months or even years ago, eventually turning into a “human to human” deadly virus.
“I think it may have been spreading among humans for some time.” Lipkin said, “how long? We may never completely rebuild this process It may have been circulating for months or even years. “
The new coronavirus is a natural product and can’t be constructed in the laboratory, and it has spread in the population before or in a relatively weak form, or even for many years, according to a new study published in the scientific journal Nature Medicine recently (March 17). The virus only triggers a pandemic when it mutates.
On March 24, Lipkin confirmed in an interview with Fox business channel that his new coronavirus test was positive. At the beginning of the new outbreak in January this year, Lipkin visited China in his own name to investigate the situation of epidemic prevention and control.
