The Delta Covid variant, which was first discovered in India, is already the dominant one in the US, according to data compiled by the US Centers for Disease Control and Prevention (CDC).

According to the estimates of the health organization, the Delta variant of Covid became dominant in the country within the two weeks ended on July 3, with 51.7% of cases being associated with this variant.

The percentage of cases associated with the alpha variant, which was first detected in Britain, and was dominant in the US so far, fell to 28.7%.

Specialist Dr Wilson told Yale Medicine that the delta variant is 50% more contagious.

“In a completely unmitigated environment — where no one is vaccinated or wearing masks — it’s estimated that the average person infected with the original coronavirus strain will infect 2.5 other people,” Dr. Wilson said.

In the same environment, Delta would spread from one person to maybe 3.5 or 4 other people.

The delta strain, which is becoming the dominant strain of SARS-CoV-2 in many countries, is more lethal and infectious than earlier strains of the virus and can cause more serious forms of the disease, especially in young people. It has now been located in every US state, health officials said.

On Tuesday, President Joe Biden encouraged Americans who have not yet been vaccinated against Covid-19 to do so to protect themselves from the widespread, highly contagious variant.

So far, initial data have shown that the Pfizer/BioNTech, AstraZeneca and Moderna vaccines are highly protective against the Delta variant, with the concentration of neutralizing antibodies being relatively low.
