According to a partnership between CDC and private testing company, the highly infectious Delta coronavirus variant may be now dominant in the United States. It has already spread to more than 96 other countries.Alexandre Bolze (senior scientist at Helix) stated on Tuesday via Twitter that the number Americans infected by the Alpha variant was decreasing. This was less than 20% of the positive tests the company sequenced on June 25.He said that the number of people infected by Delta was on the rise "10 days ago Delta represented 30% of sequences"Helix has been backed by the CDC to track the emergence of coronavirus variants. According to the company, funding from the National Institutes of Health (NIH), Helix can process up to 100,000 daily test across most of the United States.Bolze's figures do not include tests that have been sequenced elsewhere.Bolze stated on Twitter that the Gamma and Delta variants, which were first identified in India, are more common in the US than Alpha according to Helix data.He said that Delta was growing at a faster pace than Gamma in most of the states. Both viruses are more contagious than the original coronavirus variant, and both have mutations that may help them avoid the immune reaction.Data from Global Initiative on Sharing Avian Influenza Data, the world's largest central sequencing database, supports this assertion. It shows that the percentage of sequences with the Delta version increased faster than the Gamma variant in the US during June. However, both were increasing.The CDC has not officially endorsed the findings. On June 19, Dr. Rochelle Walensky, the director of the CDC, predicted that the Delta variant would be the predominant strain in the US within a matter of months.Due to the low number of US cases, the data may not be accurate. Therefore, Genbank and GISAID are likely to receive the data from the CDC.In a Wednesday report, the World Health Organization (WHO), stated that Delta would quickly outcompete all other varieties worldwide.Business Insider originally published this article.Business Insider has more:
