"Isolating cases and quarantining contacts is not going to stop this virus," WHO adviser Ira Longini, who tracked studies of the virus's transmissibility in China, said.
Report informs, citing Daily Sabah, that, according to Longini, coronavirus, with its new official name COVID-19, may affect up to two-thirds of the world population.
"Unless the transmissibility changes, surveillance, and containment can only work so well," he was quoted as saying.
According to his remarks to Bloomberg, Gabriel Leung, a public health professor at the University of Hong Kong, is on the same page as Longini.
The scientist also warned that close to two-thirds of the world could catch the virus "if it is left unchecked."
