China Media Group:
The recent infections feature outbreaks in multiple regions, a wide spread of the virus, and a large number of confirmed cases. What is your assessment of this round of infections? What features have you found from virus origin tracing? What do you think is the reason for the recent resurgence? Thank you.
Wang Hesheng:
Thank you. Now I will answer your questions. Just as you said, we have indeed seen recent infections spreading widely and occurring frequently in multiple regions. There are four main reasons:
First, since December 2021, the world has witnessed the fourth pandemic peak of COVID-19, which has lasted for 11 consecutive weeks up to now, with more than 10 million cases reported each week. These figures show that the world is still at a pandemic peak. Since the start of this year, in particular, the virus has spread rapidly in our neighboring countries and regions, producing an increasing "pressure difference" in COVID-19 spread between China and its neighbors. In the first two months of this year, the average number of daily imported infections reached 91 cases, far more than 22 cases in 2020 and 32 cases in 2021. In March 2022, the average number of daily imported infections exceeded 200, with the highest daily number exceeding 300 cases. All these indicate a significant increase in the pressure caused by the recently imported infections.
Second, the Omicron variant of the coronavirus that is now dominant worldwide, especially the Omicron BA.2 sub-variant, is more contagious and less detectable than other strains. So this makes it harder to detect the virus at an early stage. When discovered, the Omicron variant may have already spread to a wide area. And this means that it has become more difficult for us to handle and control the coronavirus.
Third, in late February, Spring Festival ended, the spring semester began, and companies and workers resumed normal work, which brought a massive flow of population. And there was also an increase in gatherings, such as meetings, training activities, weddings, and funerals. All of these have magnified and amplified the spread of COVID-19, leading to the fast spread of coronavirus and even the transmission across regions.
Fourth, some may think the Omicron variant appears to have relatively mild symptoms and is no different from the flu, then they relax their vigilance in guarding against the coronavirus and are not fully prepared to respond to COVID-19, lowering requirements for regular containment measures and emergency responses.
According to analyses and assessments by experts, this wave of global COVID-19 outbreak is still at a high level and will not come to an end soon. China will continue to face a situation where Omicron-dominated infections may occur in multiple locations simultaneously. It means that epidemic prevention and control will be even more serious and complex.
Epidemiological tracing results also show that the recent cluster infections in multiple regions of China were all caused by inbound cases. In addition, most of the people infected with the Omicron variant present mild symptoms or are asymptomatic, so it is hard to detect the source of the virus and the means of transmission vary significantly. We have discovered multiple transmission routes in different regions and found the source of the coronavirus diverse and complex. This brings huge challenges to the epidemiological tracing work and COVID-19 response.
The characteristics of this wave of the coronavirus outbreak require us to further increase sensitivity in our monitoring and early warning efforts, improve the multi-point trigger mechanism for monitoring, and effectively improve our capacity to detect the coronavirus at an early stage. Thanks.
