Since it first appeared in India at the end of 2020, the Delta variant of the new coronavirus has become the main strain in most parts of the world
.

Researchers may now know why the Delta variant strain is so successful: People infected with it produce much more virus than those infected with the original version of the new coronavirus, making it very easy to spread

The team tested the "viral load" of study participants every day during the infection process-a measure of the density of virus particles in the body, to observe how it changes over time
.

The researchers then compared the participant's infection pattern with the 63 people infected with the original new coronavirus strain in 2020

The combination of a large number of viruses and a short incubation period can explain the high transmission of the Delta variant virus
.

The sheer number of viruses in the respiratory tract means that super transmission events may infect more people, and people may begin to spread the virus sooner after infection
