As an expert on epidemic prevention and control, Zhang said the biggest lesson learnt from the COVID-19 outbreak is the necessity to combat vulnerabilities. He defined "counter vulnerability" as preparing for disasters beforehand so as to ensure continued development.

Zhang said that only when such capabilities are improved by individuals in the healthcare industry can the overall profession be improved.

Regarding the global pandemic, Zhang said that the most essential tasks are mass testing and adequate quarantine.

"If these two tasks cannot be achieved, there will definitely be a rebound after work resumes," he said. However, Zhang said he still has great confidence in the ultimate control of the pandemic: "In the history of mankind, no epidemic has truly devastated the human race, and this one is no exception."
