Covid19 : Delta variant now dominant in U.S
The delta variant of the coronavirus disease or B.1.617.2 first seen in India, will soon end up being the most dominant strain of the virus in the United States, news agencies reported on Thursday morning, adding that the delta variant constitutes almost half of the total infections in the country right now.
According to the health agency’s estimates the Delta variant became dominant in the country over the two weeks ended July 3, with 51.7% cases linked to the variant that was first identified in India. The proportion of cases linked to the Alpha variant which was first identified in Britain and had been dominant in the United States so far, fell to 28.7%. The data, which shows the estimated biweekly proportions of the most common SARS-CoV-2 lineages circulating in the United States, is based on sequences collected through CDC’s national genomic surveillance since Dec. 20, 2020.
In an interview, Dr. Anthony Faucci said, “If there was a reason to get vaccinated, this is it.” Several studies provided proof that the Pfizer and the Moderna vaccines currently being administered in the country are effective against the Delta variant. Their major concern is vaccine hesitancy among people, which has been worsened by politically induced campaigns to warn people against the vaccine. If the strain continues to spread among the unvaccinated population, it could give birth to another strain, which can be even more destructive.
The country reached its highest vaccination rate in mid-April when the seven-day average of doses administered daily topped about 3.4 million. But the rate has dropped since then. About 47.6 per cent of the US population is fully vaccinated against Covid-19, and 55.1 per cent of the population has received at least one shot as of Wednesday, CDC data show.
