Corona virus varian Delta (B1617.2) is suspected to be the cause of the spike in COVID-19 cases in various parts of the world. This variant is also still the most dominant strain today. Not finished with the Delta variant, now comes the Lambda (C37) variant which has also attracted attention lately.
The World Health Organization (WHO) says the Lambda variant has the potential to increase transmission. This variant is also thought to have increased resistance to antibodies. Like the Delta variant, Lambda is highly contagious and is thought to be more resistant to vaccines.
If the WHO prescribes varian Delta as a variant of concern (VOC), then the Lambda variant is below it with the classification of variant of interest (VOI). While much is still unknown about the strain, there were some worrying characteristics that the researchers detected.
Currently, the Lambda variant has spread mainly through South America after it was first identified in Peru in August 2020. Overall, 28 countries have identified the Lambda variant in COVID cases.
Scientists say the spread of the Lambda variant is closely related to one of the earliest known virus variants known as Alpha.
However, research shows the vaccine protects against all strains of coronavirus, including the Delta variant, and the researchers believe this was the case with Lambda.
However, to date there is insufficient data on how effective the current vaccine is in preventing infection from Lambda.
Senior researcher Kei Sato of the University of Tokyo recently told Reuters that varian Lambda can be a potential threat to humans. On the other hand, WHO is also still monitoring other variants, such as Eta, Kappa and Lota because they can all develop into threats.
