China sticks to strict anti-virus strategy amid rise of Omicron
Print Edition
As the heavily mutated COVID-19 Omicron variant sounds a global alarm, China said it will stick to its strict anti-virus policy, taking all necessary measures to eliminate infections before the new virus variant could wreak havoc.
Cases of Omicron, a “variant of concern” according to the World Health Organization have been reported in South Africa, Israel, Italy, Australia, and the United States, with multiple countries beginning to reinstate border restriction and travel bans.
China has not detected such cases so far except in Hong Kong. Its health authority said the country will stick to its current anti-COVID strategy of preventing imported cases and a domestic resurgence, noting that such an approach is also effective against Omicron.
“No matter how the virus mutates, it is still the novel coronavirus,” said Zhang Wenhong, head of the Center for Infectious Diseases at the Shanghai-based Huashan Hospital of Fudan University.
“China’s current quick response and strict anti-virus strategy can cope with various types of COVID-19 variants.”
Chinese experts, however, did not relax their vigilance. They are closely tracking and assessing Omicron’s transmission risks and its impact on existing vaccines and drugs.
“To compete with highly contagious variants, the sooner we detect an infection, the sooner we can take the initiative to rid it out,” said Ma Xiaowei, director of the National Health Commission.
All the local clustered cases in the COVID-19 resurgence since mid-October in China originated from overseas. The resurgence has spread to more than 20 provincial-level regions at its peak.
When dealing with imported Delta variant cases, most regions managed to contain the outbreak within an incubation period of about 14 days.
Aiming to contain an outbreak within an incubation period, Chinese agencies have been making full use of the “golden period,” the first 24 hours of a discovered case, to find those who were in close contact, isolate potentially infected individuals before the virus spreads, or before the infected person can transmit the virus.
Ma hailed the strategy as essential for China’s fight against COVID-19.
“Quick” has been a catchphrase during the whole process, as only through quick action can the spread of the virus be minimized. Shanghai lately managed to bring a virus resurgence under control in three days.
Immediately after three cases were reported, authorities activated an emergency response. The local government ordered epidemiological investigators to arrive at the scene within two hours, complete the core investigations within four hours, and finish the epidemiological reports within 24 hours.
China has continuously adjusted its COVID-19 prevention and control measures: from the emergency response at the beginning of the outbreak to the exploratory routine containment until August, to the current strategy of eliminating infections in a timely manner.
Alarmed by the loopholes exposed in the last resurgence of local infections, the central government has asked local authorities to remain on guard against imported cases, enhance response capacity in key areas, limit tourism and promote mass vaccination.
