Meet the Lambda variant

The unusual Lambda variant is rapidly spreading in South America. Here’s what we know.

A coronavirus variant known as Lambda, which has largely slid under the radar for the past nine months, is now causing almost all new infections in Peru.

Lambda (also known as C.37) was first detected in Peru in August 2020 and has spread to 29 countries, many in Latin America. And, since January 20, 2021, 668 Lambda infections have been reported in the United States. In Peru, Lambda is now responsible for more than 90 percent of new COVID-19 cases, a steep rise from less than 0.5 percent in December. The country has already suffered the world’s worst mortality due to COVID-19; the disease has killed about 0.54 percent of the population.

The Lambda variant likely caused the high number of infections during the second wave between the end of March and April, Peruvian Minister of Health Óscar Ugarte said in a news conference. In neighboring Chile, where the primary vaccine is China’s CoronaVac, Lambda accounts for 31 percent of sequenced cases in the last 60 days. The high case numbers are occurring even though 58.6 percent of Chile’s population is fully vaccinated and another 10 percent has received a single dose. The poor efficacy of the vaccine maybe partly to blame. A study by the University of Chile found that a single dose of the CoronaVac vaccine was only 3 percent effective, but that rose to 56.5 percent after both doses.

“Why Chile is getting such high infection rates is perplexing, and it’s likely due to several factors. Because of their high vaccination coverage, the restrictions were relaxed a little too soon, and that could have led to [a] rise in cases,” says Pablo Tsukayama, a microbiologist at Universidad Peruana Cayetano Heredia in Lima, Peru. It was Tsukayama who first spotted the Lambda variant after routinely sequencing the samples deposited between January and March 2021. “But it is also possible that the main variants in circulation, Gamma and Lambda, have some immune escape properties that lead to reduced protection from vaccines.”

1. I read it as the Lambada variant

Need new glasses

Ugh

2. Looks like I need to bone up on the Greek alphabet so I can follow along with the death counts.

3. Lambda is about half way down the Greek alphabet.

Not sure if there have been all the other variations or they just happened to like that letter.
Weird.
