BEIJING, April 22, 2020 /PRNewswire=KYODO JBN/ --

A report from Science and Technology Daily:

Since the beginning of the COVID-19 outbreak, Chinese researchers have raced

against time to trace the source and transmission route of the virus, as well

as develop test reagents.

On Dec. 31, 2019, researchers from the Wuhan Institute of Virology under the

Chinese Academy of Sciences were assigned the urgent task of conducting

whole-genome sequencing on samples sent by the Wuhan Jinyintan Hospital, which

possibly contained unknown pathogens. With strenuous efforts, the institute

managed to complete the mission in less than a week on Jan. 2, 2020, and they

shared with the world the whole gene sequence of COVID-19, winning

international recognition for their "Chinese speed."

A research team from Beijing University of Chemical Technology has also worked

around the clock to dig into the source of the virus. Some team members even

stayed in the lab on Lunar New Year's Eve.

Researchers have made arduous efforts to conduct sequence alignment based on

the whole gene sequence of COVID-19 and search the database for homology. Next,

they plan to carry out epidemiological investigations and virus source tracing

by using artificial intelligence and big data to improve the accuracy and

efficiency of the screening.

Also at the start of the outbreak, the National Institutes for Food and Drug

Control, the Wuhan Institute of Virology and the Institute of Pathogen Biology

under the Chinese Academy of Medical Sciences were among the first to research

and develop coronavirus detection products. As a result of their hard work, two

kinds of nucleic acid test kits were developed by different technological

methods using fluorescent-PCR and reversible terminator sequencing technologies.

On Feb. 8, 2020, another emergency program was launched to improve fast test

technology and products for nucleic acid, antigen and antibody testing to allow

on-site screening and rapid diagnosis among suspected patients and close

contacts of infected patients.

The release of these scientific achievements in a timely manner greatly eased

the panic during the early stages of the outbreak, and it has provided a

scientific basis for the current resumption of production and work.
