The World Health Organization classifies the delta variant as a "variant of concern," meaning it may be associated with increased transmissibility. Most likely, but some virologists say we need more information to be sure. Here's what we know so far: Is the delta variant more transmissible than the original version of the virus? So this is why even if you’re vaccinated, you can get the infection, but the chances are you will get very mild symptoms or no symptoms at all, and that the chances of getting seriously ill are really, really low.While experts agree that vaccination is the best defense against all circulating versions of the virus, there are still many unanswered questions about the delta variant. Swaminathan added that “none of the vaccines that we have currently are 100 percent protective. “The good news is that all of the WHO emergency use listed vaccines do protect against developing severe disease, hospitalisation and death due to the Delta variant”, the health agency’s chief scientist, Dr Soumya Swaminathan, said this week. The WHO says more research data are needed to confirm if the Delta variant causes more severe cases than other known variants.Īt the same time, it has urged governments to step up their inoculation drives and called on wealthy nations to ensure that vaccines are shared equitably to push back against the threat of COVID-19 surges. Reported in: 104 countries as of July 6 Vaccines effective Reported in: 74 countries as of July 4 DeltaĮarliest documented sample: India, October 2020 Reported in: 122 countries as of July 4 GammaĮarliest documented sample: Brazil, November 2020 Reported in: 173 countries as of July 4 BetaĮarliest documented sample: South Africa, May 2020 AlphaĮarliest documented sample: United Kingdom, September 2020 The Delta variant is estimated to be between 40 and 60 percent more transmissible than the Alpha variant, which was first detected in the UK, according to a number of studies. The WHO has identified four such variants of concern: Alpha, Beta, Gamma and Delta and four variants of interest: Eta, Iota, Kappa and Lambda.Īmong the four variants of concern, Delta is believed to be the most transmissible variant yet. An increase in cases creates a greater strain on a country’s healthcare resources and may lead to more hospitalisations and deaths. Other times, variations allow the virus to spread more easily and quickly which may lead to more cases of COVID-19. Sometimes, these new variants emerge and then disappear. Like all viruses, the SARS-CoV-2 coronavirus is evolving. Variants of concern: Alpha, Beta, Gamma and Delta.

Two weeks later, it had been found in 80 countries and by July 4, the number had risen to 104. By June 1, it had spread to 62 countries. The Delta variant was first detected in India in October 2020.
