COVID-19 pandemic may come and go for up to 2 years - Chinese expert

A Chinese medical expert has predicted that the new coronavirus disease (COVID-19) that has spread rapidly around the world will not disappear anytime soon and could last off and on for one or two years, reported Central News Agency (CNA).

Initially, the global outbreak of COVID-19 should peak in April and last until between May and June, predicted Zhang Wenhong, head of Shanghai's COVID-19 clinical expert team, during a recent video conference held by the Chinese consulate in Düsseldorf, Germany.

After retreating during the summer, the outbreak could reappear next winter and peak again in the spring of 2021, he suggested.

"It's possible that the virus comes and goes and lasts for one or two years," he said.

To contain the pandemic will be difficult, the expert said, because it depends on the responses of different countries and how the outbreak develops internationally.

Zhang, who is also director of the Infectious Diseases Department of Fudan University's Huashan Hospital in Shanghai, warned that the outbreak that is now raging across Europe will not be over soon.

"Forget about the idea that the pandemic will end in Europe in the near future," he told the audience, mostly Chinese expatriates and students in Germany.

What China did to contain the virus' spread was to stop all activities in cities, Zhang said.

"Only if the whole world agrees to stop moving for four weeks, it might be able to contain (the pandemic)," he said, but "I can't imagine that will happen."

Echoing the general consensus about the new coronavirus, Zhang said it is not as fatal as its cousin that caused the severe acute respiratory syndrome (SARS) epidemic in 2003.

Compared with the 10 per cent mortality rate seen among SARS patients, COVID-19 patients in Germany, Japan and areas in China outside of Hubei seems to be a mere 1 percent at present, Zhang said.

COVID-19 spreads very quickly, however, and could leave 20 per cent of those infected very sick despite its low fatality rate, putting huge pressure on the health care systems of cities, he said.

For Europe to contain the pandemic, it has to substantially increase its deployment of medical resources in local communities, expand its capacity to treat those suffering from severe symptoms, and control all kinds of activities in cities, he contended. -- BERNAMA
