在加拿大
Delta还在盛行，疫苗的保护率也不高，后面更厉害的Lamda要来，没完没了。。。
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.
A doomsday COVID variant worse than Delta and Lambda may be coming, scientists say
Delta has shown how destructive new strains of COVID can get. Scientists fear future mutations of the virus could be even worse: "Delta on steroids."
