The new COVID-19 variant Omicron, which the World Health Organization has termed a "variant of concern" and is more transmissible than the dominant Delta strain, will not have a major influence on China at the current phase, Zhang Wenhong, a Shanghai doctor widely known for his pandemic fight, wrote on his Sina Weibo on Sunday.

"China's current strategies of rapid response and dynamically zeroing cases will be able to cope with various types of variants of the novel coronavirus," wrote Zhang, leader of the Shanghai team of experts in the clinical treatment of novel coronavirus pneumonia cases.

"China is currently accelerating building up scientific support, including reserves of effective vaccines and drugs as well as public health and medical resource that can support China's large-scale opening to the world and empower the country to deal with normalized pandemic fight in the next stage," he wrote.

With science and solidarity, the country will cope with the Omicron variant properly just as how it has done with Delta, said Zhang, who is also director of the infectious diseases department at Huashan Hospital Affiliated with Fudan University.
