As the number of coronavirus cases jumps dramatically in China, a top infectious-disease scientist warns that things could get far worse: Two-thirds of the world's population could catch it.
So says Ira Longini, a World Health Organisation adviser who tracked studies of the virus's transmissibility in China.
His estimate implies that there could eventually be billions more infections than the current official tally of about 60,000. There are still no confirmed cases in New Zealand.
If the virus spreads to anywhere near that extent, it will show the
limitations of China's strict containment measures, including
quarantining areas inhabited by tens of millions of people. WHO
Director-General Tedros Adhanom Ghebreyesus has credited those steps
with giving the rest of China and the world a "window" in which to
prepare."
