Scientists and medical workers uncover Omicron variant mysteries
    2022-01-20  08:53    Shenzhen Daily

SHENZHEN scientists and medical workers have contributed their share of wisdom in the global race against COVID-19, with major breakthroughs in uncovering the secrets of the Omicron variant, Shenzhen Economic Daily reported yesterday.

Before the first Omicron infection was reported in Shenzhen on Sunday, Wang Peiyi, a professor from the Southern University of Science and Technology, had co-authored and published a paper with other scientists from domestic research institutes and universities to reveal the receptor binding and complex structures of human ACE2 to spike RBD from the Omicron and Delta variants.

The paper was published online on international top academic journal Cell on Jan. 6.

The Omicron and Delta variants are the two most important among the five variants of concern (VOCs) defined by the World Health Organization. The Omicron variant has appeared in 128 countries and regions and has captured worldwide attention, while the Delta variant is the most contagious mutation so far.

Wang and his fellow researchers’ study has provided a key foundation for follow-up vaccine and drug research and development, according to the Daily report.

Lu Hongzhou, president of the Third People’s Hospital of Shenzhen, also recently published a paper on the Electronic Journal of Emerging Infectious Diseases. The paper has reviewed the molecular mechanism underlying Omicron’s immune invasion, its milder pathogenicity and enhanced transmissibility, and further provided scientific suggestions to prevent and control it.

Lu put forward suggestions based on the studies of Omicron — the existing public health measures are effective, timely diagnosis and quarantine are the most effective methods to stop transmission, establish herd immunity and expand booster shot vaccinations as soon as possible, develop specific vaccines for Omicron, and screen and develop effective drugs and antibodies against Omicron.

The data security research institute established by Harbin Institute of Technology, Shenzhen and QI-ANXIN Technology Group Inc., a cybersecurity service provider, has also leveraged their scientific prowess to help in the fight against the virus.

The institute has used big data technology to ensure the security and privacy protection of epidemic data in storage, transmission, use and even attack. (Zhang Yu)
