In the final days of November 2021, a new chapter of the pandemic quietly announced itself at Brazil's airports and laboratories. Rio de Janeiro and São Paulo — two of the country's great urban centers — found themselves tracing the earliest footprints of the omicron variant, carried home by travelers returning from South Africa. The cases are few and mild for now, but health authorities understand that what arrives at the border rarely stays there, and the work of sequencing, isolating, and watching has begun in earnest.
