What do I need to know about the delta variant? | India News


It is a version of the coronavirus that has been found in more than 80 countries since it was first detected in India. It got its name from the World Health Organization, which names notable variants after letters of the Greek alphabet.
Viruses are constantly mutating and most changes are not worrisome. But there are concerns that some variants could evolve enough to become more contagious, cause more serious disease, or evade the protection that vaccines provide.
Experts say that the delta variant spreads more easily due to mutations that make it adhere better to cells in our body. In the UK, the variant is now responsible for 90% of all new infections. In the US, it accounts for 20% of infections and health officials say it could also become the dominant type in the country.
Whether the variant makes people sicker is not yet clear, as more data needs to be collected, said Dr. Jacob John, who studies viruses at Christian Medical College in Vellore, southern India.
Studies have shown that available vaccines work against variants, including the delta variant.
Researchers in England studied how effective the two-dose AstraZeneca and Pfizer-BioNTech vaccines were against it, compared to the alpha variant that was first detected in the UK.
The vaccines protected those who received both doses, but less so among those who received one dose.
That is why experts say that it is important to be fully vaccinated. And that’s why they say that making vaccines accessible globally is so critical.
