Data | Delta variant drives COVID-19 infection surge in the world

Studies show that the vaccines are highly effective in reducing related hospitalisations

Across the world, the new are on the rise again for the past two weeks. The spike is not uniform across all countries, with many nations showing a significant decline, too, in cases in the considered period. However, a common feature observed across most countries that are exhibiting a spike is a parallel increase in the share of the 8.1.617 variant of COVID-19, or the Delta , which was first identified in India last year. The effectiveness of most widely used vaccines does reduce against this variant. However, studies show that the vaccines are highly effective in reducing related hospitalisations. The graph shows the rolling 7-day average of daily new confirmed COVID-19 cases worldwide. Since June 23, the global case curve has been going up again. From over 3.59 lakh cases on June 22, the new infections increased to over 4 lakh cases as of July 6.
