Delta Plus Variant: Will the third wave of corona come only from the Delta Plus variant? Know the answers to more such big questions


BEIJING: Researchers at the Guangdong Provincial Center for Disease Control and Prevention in China found that the delta viral load, which is a measure of the density of viral particles in the body, is about 1,000 times higher in people infected with the delta variant. Infected with the original coronavirus strain, Nature reported.

The study found that people infected with the delta version of COVID-19 produce far more virus than those infected with the original version of the coronavirus, making it much easier to spread. According to current estimates, the delta variant may be more than twice as high as the original strain of SARS-CoV-2, the virus that causes COVID-19. The variant, which was first identified in India in late 2020, has now become the dominant strain and has spread to at least 111 countries.

The researchers tracked 62 infected 3D who were quarantined after being exposed to Covid-19 and tested their viral load every day during the course of the infection to see how it changed over time. The researchers then compared the infection patterns of the participants with those of 63 people who contracted the original SARS-CoV-2 strain in 2020. The findings, posted preprints, showed that the virus was detectable in people with the delta variant up to four days after exposure. On the other hand, it took an average of six days for the original strain to appear in people. This suggests that the delta replicates very rapidly, said Jing Lu, an epidemiologist at the CDC in China. The study found that people infected with Delta also had a viral load 1,260 times higher than those infected with the original strain.
