Study: The delta variant is extremely contagious – Human – Science and technology

The delta variant is the most contagious version of the coronavirus in the world. It spreads about two to three times faster than the original version of the virus and has up to a thousand times more viral load.

This follows from a study by Chinese scientists, from which the American public radio NPR was quoted.

Researchers from the Regional Center for Disease Control and Prevention in Guangdong Province, China, have published a study on the expert discussion server Virological.org.

Their findings suggest that the delta variant spreads through the airways faster and in far greater amounts than the original variant. According to experts, the amount of virus in the body usually determines how contagious a particular person is.

As the delta has up to a thousand times higher viral load than the original variant, this variant is much more contagious. The study’s authors came to this conclusion after analyzing samples from 167 people who became infected with the delta variant in Guangzhou. They compared the viral load with data from people who became infected with the coronavirus in early January 2020. Their results show that people infected with the delta variant are much more infectious to their surroundings. On average, it takes about four days for the mutation to reach a detectable level in the human body. In the original variant, it was six days.

In the published document, the researchers emphasized the importance of isolating people from the environment for a period of at least 14 days immediately after contact with the infected. A similar approach is recommended by the US Centers for Disease Control and Prevention (CDC), concludes the NRP.
