Covid cases in India may be on a steady decline but several countries across the world are now grappling with a renewed surge in cases. Reason: The highly contagious Delta variant.
First identified in India last year, the fast-spreading variant has now become dominant in countries like the US and UK, leading to a significant spike in recent cases. It was also responsible for India’s devastating second Covid wave.
In UK, Covid-19 infections have quadrupled in a month since early June, a large prevalence study showed on Thursday.
The daily cases on Wednesday touched the 32,000-mark after nearly six months and are likely to increase further.
UK health secretary Sajid Javid warned that cases could rise up to 100,000 per day after restrictions are lifted on July 19.
Research showed that the cases are estimated to be doubling every six days as a new wave fuelled by the Delta coronavirus variant picks up pace.
The spike comes at a crucial juncture as the UK is planning to completely lift restrictions such as wearing of masks and practicing social distancing norms in public places.
In the US too, Covid cases are rising rapidly as the highly contagious Delta variant dominates and vaccinations stagnate, data showed on Wednesday.
The seven-day-average of new cases was 13,859 as of July 6, up 21 percent compared to two weeks earlier, according to the Centers for Disease Control and Prevention (CDC).
The Delta variant accounted for around 52 percent of cases in the two weeks ending July 3, according to the CDC.
