The Lambda variant (C.37) has been getting a lot of news coverage in the US the past week. This won’t last.

In head to head which-variant-out-competes-the-other matchups, Lambda does not quite hold its own against Gamma (see Chile) and gets creamed by Delta (Mexico) and with Gamma already prevalent, never got a toehold in Brazil. Lambda is more transmissible than wild type, and maybe Alpha (B.1.1.7). Its success in Peru is likely a founders effect.

Expect Lambda to vanish from US headlines in the coming week or two. We are 99% Delta by then. Don’t take my word for it, browse the countries tab in Covariants.org for yourself (but remember some nations have statistically very small samples of genotyped samples, and should be ignored.)
