The Indian strain of the coronavirus, referred to as the Delta variant, will become dominant worldwide for an extended period of time due to its high transmission rate and short incubation period. This opinion was expressed by a medical expert on June 21.


Previously, the World Health Organization (WHO) identified four variants of coronavirus that are of particular concern due to their high spread rate. Among these strains, the "Delta" variant was included, which was first discovered in India in October 2020.

Wei Sheng, professor at Huazhong University of Science and Technology, during an interview with Central Television China (CCTV) noted that the Delta variant ranks first among the four coronavirus strains of concern in terms of spread rate.

of the options listed so far of concern, it has the highest transmission speed, so it will undoubtedly be firmly at the center of distribution for some time," said Wei Sheng.

And, as Wei Sheng points out, as a major international city, Guangzhou is facing enormous pressure in epidemic prevention and control.

Some people worry that currently available COVID-19 vaccines will not be able to effectively protect from Delta. However, as the professor assures, vaccination remains the main way to fight a new type of coronavirus, since vaccines against COVID-19 will at least reduce the risk of comorbidities.

"According to some recent research findings, vaccines are widely that we currently use are still effective against the Delta variant.In addition, especially from the experience in epidemic prevention and control in Guangzhou, we can also see that in people who have completed their COVID-19 vaccination, even with if infected, the risk of developing serious complications is much lower than for those who have not been vaccinated. And this shows that the vaccines that we use now have had a protective effect on our people," he stressed.

as of Sunday, On June 20, a total of 1,029,223,000 doses of COVID-19 vaccines were administered in mainland China, the National Health Commission said on Monday. And by 6:00 pm on Sunday, more than 100 million doses of the COVID-19 vaccine had been administered in southern China's Guangdong province.
