Chinese health experts wave off concerns of second, deadlier wave of coronavirus
Chinese health experts involved in the country’s fight against the coronavirus believe the worst is now over, downplaying warnings that the disease could become seasonal or that a deadlier “second wave” could hit later in the year.
As the pandemic continues to spread overseas, a growing number of countries are bracing themselves for a worst-case scenario in which COVID-19 remains in circulation until next year at the earliest.
But medical advisers in China have expressed confidence that the country’s strict containment measures have done enough to ensure that the outbreak can be brought under complete control, domestically at least, within weeks.
Though they remain wary of the risks of “importing” cases from overseas, they say China should be capable of eliminating COVID-19 in the same way it eliminated Severe Acute Respiratory Syndrome (SARS) in 2003. SARS was eventually contained after the government imposed stringent screening and quarantine measures.
“For me, a second outbreak (of coronavirus), a domestic outbreak in China, wouldn’t be a great concern,” said Cao Wei, deputy director of the Department of Infectious Diseases at the Peking Union Medical College Hospital.
She told a briefing on Monday that while China needed another month to make a final judgment, the existing prevention and control measures should be enough to bring the epidemic to an end domestically.
The World Health Organization has said the coronavirus reached a peak in China around late February. Zhong Nanshan, a senior government adviser who helped detect and defeat SARS in 2003, said it “could be over by June” if other countries take the required action.
On Wednesday, there were no new domestic cases in the disease’s epicentre of Wuhan for the first time since the outbreak began. However, “imported” infections reached a record 34, and have outnumbered domestic transmissions for five consecutive days.
Ian Henderson, director of the Institute for Molecular Bioscience at the University of Queensland, said China’s actions to contain the virus have been “extraordinary” but there could be a second outbreak, this time imported.
“(What) remains possible is that as controls around isolation are relaxed in China, with a population that is still susceptible, then the virus may resurge if it has not been eradicated elsewhere,” he said.
