Yes, but nothing very authoritative. No variants are being reported on beyond the vague statement that there are some.
Chile has no land border with Brazil but it does with Peru. And Peru is not much better off than Brazil.
Also Chile has not closed the air border between Chile and Brazil though it did bring in restrictions about 10 days ago (PCR test on arrival, held in quarantine until the result).
Clearly though a major worry has got to be the strains in Brazil. And for as long as the virus is rampant over there then more and more variants will occur. In my opinion the situation in Brazil is a World health issue. Brazil should be totally locked off from the outside world until they get a grip.
