Delta variant ‘more transmissible’, while other strains now gain ground


The Delta variant of the coronavirus has already spread to over 80 countries, according to the World Health Organization.

Health officials and experts first detected the COVID-19 Delta variant in India last December. Just months after the initial detection, it has already spread across 80 countries, as per the World Health Organization.

The strain in question is now the dominant variant in the United Kingdom. Due to its high transmissibility rate, it has even overtaken the local Alpha variant in the country.

Reports said that its continued spread across the globe worries experts from various countries. Moreover, it now has multiple mutations, which cause more concern among the public.

As this dynamic remains apparent, WebMD released an informative report about the B.1.617.2 strain. The key points are that the variant is spreading fast, and reportedly causes more severe symptoms.

Transmissibility rate of the Delta variant

Experts believe that the Delta variant is 43 percent to 90 percent “more transmissible” than the earlier COVID-19 strains. In addition to this, many reportedly see that it is 30 percent to 100 percent “more infectious” than the Alpha variant.

The publication noted that health officials remain uncertain as to why the B.1.617.2 strain has these kinds of features and impacts. But, studies reportedly suggest that the “changes in the variant’s protein” allow it to enter human cells easily.

In terms of the symptoms, it reportedly appears to be “more severe” in comparison to the other COVID-19 variants. Patients who contract the Delta variant may more likely end up in the hospital as the risk seemingly doubles.

Other health experts also added that people who have the B.1.617.2 strain appear “sicker” than those who have had COVID-19 infections early in the pandemic. Moreover, their conditions reportedly “go downhill much faster.”

Based on data from the United Kingdom, the Delta variant seems to impact more those who are under the age of 50, especially children. Experts asserted that this group of individuals are 2.5 times more at risk to contract the virus.

What about the Gamma variant?

As the concerns over the Delta COVID-19 variant continue to grow, other health officials are seemingly worrying over other strains. In the United States, the Gamma variant is now “gaining ground,” according to CNN.

There is reportedly evidence, suggesting that the variant is more resistant to vaccines and antibody treatments. It exhibits “significantly reduced susceptibility,” especially to the treatment from Lilly, as per the Center for Disease Control and Prevention.

Experts first detected the Gamma variant in Brazil. The World Health Organization classified it as one of the four global variants of concern, alongside the Delta variant.
