BUENOS AIRES, Argentina (AP) — After a reprieve of months, confirmed cases of COVID-19 are surging in the southern tip of South America. But officials in Argentina, Chile and Uruguay hope high vaccination rates mean this latest wave will not be as deadly as previous ones. At the same time, there is concern that many people are not ready to once again take on the prevention measures that authorities say are needed to ensure cases remain manageable. Cases have been steadily increasing for weeks, largely fueled by the BA.2 version of the omicron variant.
