(CNN) — A coronavirus variant first detected in India in February has now gone global, spreading to dozens of countries and raising fears that the strain will overwhelm health care systems, reverse reopening plans and even potentially undermine the rollout of vaccines.

Experts believe the B.1.617 variant is driving the huge wave in infections seen across India in recent weeks. The country now makes up 50% of Covid-19 cases and 30% of deaths from the virus globally, according to the World Health Organization (WHO).
