A senior Chinese official has said the virus can infect people via airborne transmission, but an Australian expert says more evidence is needed.
According to
a report in local news site
China Daily, the deputy head of the Shanghai Civil Affairs Bureau, Zeng Qun, revealed the potentially troubling development over the weekend at a media briefing concerning government efforts to contain the virus’ spread.
Mr Qun said transmission routes of the coronavirus included direct transmission, contact transmission and aerosol transmission.
‘Aerosol transmission refers to the mixing of the virus with droplets in the air to form aerosols, which causes infection after inhalation, according to medical experts,’ he said.
‘As such, we have called on the public to raise their awareness of the prevention and control of the disease caused by family gatherings.’
While Associate Professor Ian Mackay, a virologist at the Australian Infectious Diseases Research Centre, told
newsGP he would not be surprised if coronavirus could be transmitted by an airborne route, he said there is ‘zero public-reviewed experimental evidence’ to support the claim.
‘That evidence would need to show that infectious virus in suitable quantities to start an infection in a susceptible host, is present in the airborne gel-like “droplet nuclei” captured from the air,’ he said.
‘At the moment this is just a pronouncement without supporting evidence. We have to be careful because we have seen numerous false starts and wild claims around this virus, which have all lacked any evidence, quality expert review, or slow and careful consideration before publication or any expertise associated with their original analysis.’
Meanwhile, doctors in New South Wales have
reportedly made a ‘research breakthrough’, according to the state’s Health Minister Brad Hazzard. Minister Hazzard said extensive testing on an isolated patient at Westmead Hospital has allowed scientists to isolate the virus and study eight variants, producing two full genome sequences in the process.
