![]() ![]() ![]() The Delta variant of the coronavirus, first discovered in India, is estimated to be 40 percent more transmissible than the Alpha variant that caused the last wave of infections in the UK, Britain's health minister said Sunday. The vaccines are able to handle this.”Ĭommuters wearing face coverings due to Covid-19, enter Oxford Circus London Underground station in central London on June 7, 2021. “In most cases, we have a cushion of magnitude in circulating antibody and other cellular responses. Vaccine maker Moderna released results Tuesday showing that blood taken from vaccinated people could neutralize Delta, as well as other variants including Alpha, the Beta or B.1.351 variant first seen in South African, and Gamma, or P.1, which has swept Brazil. “But if you are not vaccinated, then you are in trouble.” “The good news is if you are vaccinated – and fully vaccinated means two weeks after your last shot – then there is good evidence that you have a high degree of protection against this virus,” Murthy told CNN’s Erica Hill Wednesday. Real life and laboratory evidence both suggest that fully vaccinated people are protected against the Delta variant. Vaccines protect against it - but not perfectly The ECDC estimates its about 40% to 60% more transmissible than the Alpha variant – making it about half again as contagious. “This is, again, a serious threat and we are seeing it spread among unvaccinated people.” “We learned this virus, a variant of Covid, is highly transmissible – the most transmissible we’ve seen to date,” US Surgeon-General Dr. The virus carries a cluster of mutations, including one known as L452R, that helps it infect human cells more easily. “Delta is the most transmissible of the variants identified so far,” Tedros Adhanom Ghebreyesus, director-general of the World Health Organization, said Friday. Samples must be shipped to special labs for genomic testing, so the CDC and companies such as Helix extrapolate from the actual test results they get back. Standard tests to diagnose Covid-19 cannot tell which variant someone is infected with. It seems to be on its way to becoming the dominant lineage in the US.” “Here in the US it is doing very similar things. That is strong head to head evidence that it is a better transmitter,” Andrew Pekosz, a professor of immunology and molecular microbiology at Johns Hopkins Bloomberg School of Public Health, told CNN. “The data from England has shown that it outcompeted the Alpha variant in that population. Mark Mulligan, director of the NYU Langone Vaccine Center, told an International Antiviral Society–USA briefing Tuesday. “Every two weeks for the last month or two this has been doubling,” Dr. Genetic testing company Helix tells CNN it estimates Delta accounts for 40% of cases in the US at present.

It accounted for 10% of lineages as of June 5, meaning its prevalence more than doubled in just two weeks. It’s been reported in all 50 states, plus Washington, D.C. In the US, the Centers for Disease Control and Prevention now estimates the variant accounts for 26% of new Covid-19 cases – or at least, that it did as of June 19. Here’s what is known about the variant so far:īy mid-June, the Delta variant accounted for 99% of Covid-19 cases in the UK, according to Public Health England, and it is set to account for 90% of cases in Europe by the end of August, according to the European Centre for Disease Prevention and Control. The World Health Organization says the Delta variant, also known as B.1.617.2, has spread to at least 85 countries since it was first identified in India last fall. Ireland delayed plans to resume indoor service in bars and restaurants and US officials urged Americans to get vaccinated to stop its spread. Australia’s Prime Minister, Scott Morrison, announced looser vaccination policies to try to get more people immunized before the variant could spread. ![]() Four major Australian cities went into a four-day “circuit-breaker” lockdown this week to try and stop it from spreading.
