Japan discovered the first Covid-19 patient infected with Lambda variant

[ad_1]

The first Covid-19 patient infected with the Japanese Lambda variant was a female, about 30 years old, returning from Peru on July 20 and entering at Haneda airport.

Tests of this female passenger at the airport showed positive results for the SARS-CoV-2 virus that causes Covid-19. The patient did not have any symptoms.

The analysis results of the National Institute of Infectious Diseases of Japan later confirmed that the female patient was infected with the Lambda variant.

According to some early in vitro studies, the Lambda variant carrying two mutations T76I and L452Q has the potential to increase infectivity compared to the original strain of SARS-CoV-2.

According to the World Health Organization (WHO), the Lambda variant was first detected in Lima (Peru) in August 2020. The variant is also known as C37 or “Andean variant”.

In Peru, the Lambda variant quickly accounted for the majority of COVID-19 cases (81% of all genetic sequences analyzed from April 2021).

After that, the Lambda variant has spread significantly in South America (Chile, Ecuador, Argentina, Brazil) and is now present in about 30 countries.

France detected the first new Lambda variant in early May 2021. The UK issued a warning about this new variant in early July 2021.

In the US, the first case of Lambda variant was detected in a hospital in Houston at the end of July 2021.

The French Public Health Agency assesses that there is still a lack of data on the impact of the Lambda variant on public health as well as the competitiveness of the Lambda variant against other variants, especially the may be in the list of VOCs.

According to some early in vitro studies, the Lambda variant carrying two mutations T76I and L452Q has the potential to increase infectivity compared to the original strain of SARS-CoV-2.

Scientists are warning that the world has entered a new dangerous phase of the Covid-19 pandemic. Virologists say that the SARS-CoV-2 virus may have evolved into more dangerous variants, but so far has not been detected because the level of infection in the community is not large enough.

A study by the Austrian Institute of Science and Technology published on July 30 found that, in addition to spreading in countries with low vaccination rates, vaccine-resistant strains have a higher risk of appearing when more than 60% of the population is affected. population of a community is vaccinated and epidemic prevention measures such as mask wearing and social distancing are lifted.

The formation of a vaccine-resistant variant at that time could lead to evolutionary loops of variation, the study said.

The WHO classification “variants of concern”, named after the Greek letters Alpha, Beta, Gamma and Delta, all appeared in the second half of 2020, although it took some time for them to spread. more widespread.

The next list of “variants of concern”, which are thought to be more contagious or resistant to vaccines, include Eta, Iota, Kappa and Lambda.
