SANTIAGO (Reuters) – Scientists in Chile are investigating a possible mutation of the novel coronavirus in southern Patagonia, a far-flung region near the tip of the South American continent that has seen an unusually contagious second wave of infections in recent weeks.

Dr. Marcelo Navarrete of the University of Magallanes told Reuters in an interview that researchers had detected “structural changes” in the spikes on the distinctive, crown-shaped virus. He said research is underway to better understand the potential mutation and its effects on humans.

“The only thing we know to date is that this coincides in time and space with a second wave that is quite intense in the region,” Navarrete said.

The Magallanes region of Chile is largely a remote, glacier-strewn wilderness dotted with small towns and the regional hub Punta Arenas, which has seen cases of COVID-19 spike in September and October following a first wave earlier
