Since the outbreak of the COVID-19 pandemic, China has invested in targeted and pragmatic efforts to contain the spread of the virus.
Adopting more scientific and precise measures is the key to achieving the best results with minimum costs, while minimizing impact on economic and social life.
This November, the Joint Prevention and Control Mechanism of the State Council released 20 measures to further optimize the country's COVID-19 strategies.
According to the new measures, it will no longer identify the secondary close contacts and medium-risk areas, and will cancel the circuit breaker mechanism, under which inbound China flights were suspended if it was found that an airline had a certain number of passengers onboard who, upon landing, tested positive for COVID-19.
Seen from the stages of virus evolution, it is highly likely that COVID-19 will stabilize and become less virulent. The dynamic variation of the virus has always been the prerequisite for optimizing and adjusting anti-virus measures, Zhang Boli, an academician at the Chinese Academy of Engineering, told Science and Technology Daily.
According to recent data, most of the confirmed cases are asymptomatic. The proportion of severe illness and death is low, which means that the virus is less pathogenic, said Zhang.
Awareness is still required of the complexity and recurrence of the pandemic. The adjustment of the control measures is based on the changes of the situations, said Zhang, noting that only by resorting to more scientific and precise prevention and control measures can a balance be struck between pandemic prevention and socioeconomic development.
Zhang warned that adhering to wearing masks, washing hands frequently and having few gatherings is a very effective control measure. Those having close contact with an infected person are suggested to take traditional Chinese medicine as early as possible, to reduce the possibility of being tested positive.
