The region where the Lambda variant is particularly active is South America. According to the Pan American Health Organization (PAHO), the Lambda variant caused nearly 82% of Covid-19 cases recorded here in May and June 2021.
According to Jairo Mendez, PAHO Regional Advisor for New Viral Diseases, the Lambda variant may be more infectious, but further research is needed so it cannot currently be compared with other variants such as Gamma and Gamma. Delta.
Mendez also emphasized that as the SARS-CoV-2 virus continues to evolve, it may become more infectious, but it is unlikely to be more virulent.
“We must emphasize that the epidemiology of the virus and the increase in the number of infections are multifactorial. For this reason, we still need to work to control the disease and reduce transmission,” Mendez said.
Meanwhile, Public Health England (PHE) said that the UK had recently detected a number of cases of Covid-19 caused by the Lambda variant. And PHE found that the new variant had “increased infectivity or the potential to increase resistance to neutralizing antibodies”. But PHE also thinks more research is needed.
A study by the NYU Grossman School of Medicine published on July 3 found that the Covid-19 vaccine is in fact effective against the Lamba variant. This study has not been peer reviewed.
Information about the Lambda variant was announced amid Europe’s response to the Delta variant. The Delta variant is thought to carry mutations that make it easier for the coronavirus that causes Covid-19 to attach to human body cells.
As such, the Delta variant is easier to infect others than the regular virus version. Covid-19 vaccines in Western countries are believed to still provide strong protection against the Delta variant.
According to many experts, 70% of the global population needs to be vaccinated against Covid-19 to achieve herd immunity. By the end of June 2021, only about 10.4% of the world’s population had been vaccinated against Covid-19, of which low-income countries only accounted for about 0.9%. In many developing countries, many health care workers are not even vaccinated.
