Delta variant may affect recovered patients 0:32

(CNN Spanish) – While authorities around the world monitor the progress of the delta variant of the coronavirus with concern, now the lambda variant has been designated as an Investigational Variant (VUI) by the English health authority Public Health England due to international expansion and several notable mutations. .

The lambda variant was classified as a Variant of Interest by the World Health Organization (WHO) on June 14. It was first identified in August 2020, and its origin is believed to be in Peru.

Lambda has been detected in 29 countries, and many of them are mainly found in Latin America, according to the WHO.

Among the countries with the highest prevalence of the Lambda variant are Chile— “with a 31% general prevalence among the sequences since the first time it was detected in Peru— says the WHO. Peru (9%), Ecuador (8%) and Argentina (3%).

According to the WHO, “authorities in Peru reported that 81% of covid-19 cases sequenced since April 2021 were associated with Lambda.”

There is currently no evidence that the Lambda variant causes more serious illness or makes current UK coronavirus vaccines less effective, PHE added. To date, six cases of lambda have been identified across the UK, all related to overseas travel, PHE said.
