Coronavirus ‘deadlier than it looks’, virologist warns
The man spearheading Australia’s efforts to develop a vaccine for the coronavirus has warned that the contagion could -become more deadly as it spreads.
The warning from Australian Animal Health Laboratory director Trevor Drew came as China reported the number of infections had surged by nearly 2000 in a day and more countries closed their borders to its nationals.
The death toll in China, the epicentre of the pandemic, has hit 213, while 21 other countries have confirmed cases of the disease, -spurring the World Health -Organisation to declare a global emergency. The US warned its -citizens not to travel to China.
Nine people are ill with coronavirus in Australia. A chartered Qantas Boeing 747 is due to leave Sydney on the weekend to evacuate Australians from the locked-down -city of Wuhan in central China to a quarantine centre on Christmas Island, where they will stay for a fortnight. About 600 Australians are understood to be stranded in Wuhan, but only a quarter of them have registered to return home.
Melbourne’s Monash University will delay the start of semester one classes for a week due to the “unprecedented situation” of -students and staff being unable to return in time from overseas. Orientation week will also be postponed, the university -announced late on Friday.
Professor Drew said early indications that the disease was killing less than 2 per cent of victims in China could be misleading -because of the potential for it to evolve rapidly and gain -potency. He spoke out as the first batch of a world-first Australian-grown virus arrived at a CSIRO lab outside Geelong, paving the way for a fast-tracked vaccine to enter preclinical trials within weeks.
