In late July, HV.1 accounted for just 0.5 per cent of Covid-19 cases in the US, CDC data showed and by September 30, HV.1 made up 12.5 per cent of cases. Then there is a newer variant called JN.1, which has one more mutation than Pirola. These include BA.2.86 or Pirola, which has an extra 36 mutations that are distinctive from XBB.1.5. NBC News reports that scientists are not overly worried about new variants such as HV.1, but there are several highly mutated strains which are more of a concern. We’ve all learned that by now," before adding that HV.1 is still very close to the existing omicron subvariants. Schaffner said: "The COVID family of viruses likes to mutate. HV.1 descends from EG.5 and is a sublineage of omicron XBB.1.9.2, according to the CDC's SARS-CoV-2 lineage tree.

William Schaffner, professor of infectious diseases at Vanderbilt University Medical Center. Whilst overall Covid-19 cases and hospitalisations have been in decline recently, the HV.1 strain is becoming more prevalent - and it's thought the winter season will see a further increase, according to Dr. All of the most prevalent Covid-19 strains in the US are offshoots of Omicron, which first appeared in November 2021. Data from the US Centers for Disease Control and Prevention revealed that HV.1 was responsible for an estimated 25.2 per cent of all new Covid-19 cases during the two-week period ending on October 28.įollowing HV.1, the next most common variant in the US was EG.5, which accounted for up to 22 per cent of cases, followed by FL.1.5.1 or "Fornax", and XBB.1.16 or "Arcturus". The new Omicron subvariant is now dominating other strains, including EG.5 aka Eris.įrom the end of October, HV.1 has been responsible for more than a quarter of all Covid-19 cases, with health officials examining the new variant in preparation for a possible winter Covid-19 surge. Since India has suspended flights to and from the UK, it can be hoped that the new strain does not spread like wildfire in India.A new Covid-19 variant has emerged in the United States and is sweeping across the nation. But confirmation hasn’t come in from the Government. So far, health officials have confirmed that 4 people coming in from the UK, (2 in Kolkata, 1 in Tamil Nadu and 1 in Karnataka) have tested positive for the B117 virus. Healthcare experts fear that the virus strain has already arrived in India. However, scientists have already started new research into the vaccine’s efficacy in building an immune response to the B117 virus. The effectiveness of the COVID-19 vaccine is still in anticipation. Will vaccines immunize us against this strain? Its only danger lies in the fact that it is more communicable. Experts have also found that the B117 virus does not cause a more severe infection than the other strains. Reproduction number refers to the number of people who can be infected from 1 infected person.īut there is good news. The reproduction number of this UK strain is also higher than other strains.
