A doomsday COVID variant worse than Delta and Lambda may be coming, scientists say
Delta, like most of the other variants, blindsided us, worsening and extending the pandemic. When the damage from Delta starts to subside, what other variants will be lurking just behind it to pull us back down again? The World Health Organization is already keeping an eye on several: Eta, which is now in several countries; Kappa, which arose in India; Iota, which first popped up in New York City—and especially Lambda, which has torn through Peru and shows signs of having unusual success in infecting fully vaccinated people, according to one early study. It has already spread to Argentina, Chile, Ecuador as well as Texas and South Carolina.
