The war between humans and the new crown virus is far from over
This new variant is Lambda, also known as C.
Initially, infections caused by lambda were relatively rare
The WHO reported in mid-June that since April 2021, 81% of the cases detected in Peru were caused by the lambda variant
Understanding the lambda mutation and its virological characteristics (such as transmissibility, virulence, immune escape, and pathogenic mechanisms) may help us prepare for its large-scale spread
Are the Lambda variants more contagious?
Are the Lambda variants more contagious? The Australian "Dialogue" magazine reported that preliminary research data on lambda showed that lambda is more contagious, and it is more likely to infect human cells than the original new coronavirus and variants of alpha and gamma
A study published on the Biology Preprint website BioRxiv in early July showed that there are several genetic mutations in the spike protein of Lambda, making it twice as infectious as the original strain
What are the symptoms of lambda infection?
What are the symptoms of lambda infection? William Schaffner, an infectious disease expert at the Vanderbilt University School of Medicine in the United States, said that the symptoms of infection with the Lambda variant are considered to be the same as those of other new coronaviruses
According to the US Centers for Disease Control and Prevention, these symptoms include: fever or chills; cough; shortness of breath or difficulty breathing; fatigue; muscle or body pain; headache; loss of new taste or smell; sore throat; nasal congestion or runny nose; Nausea, vomiting and diarrhea
Is the vaccine effective against the Lambda variant?
Is the vaccine effective against the Lambda variant? Researchers from the University of Tokyo in Japan found that Lambda is more resistant to vaccines than other mutant strains
A Polish professor at the Mayo Clinic in the United States warned that, in general, the more people who do not wear masks and are not vaccinated, the more likely the virus will mutate in the future, including mutations that may completely escape the vaccine
WHO: Or name variants after constellations
WHO: Or name variants after constellations Currently, WHO names different variants of the new coronavirus with 24 Greek letters
Recently, according to the British Sky News website, WHO is considering that once the Greek letters are used up, new coronavirus strains will be named with constellation names, such as Orion, Leo, Gemini and Aries
Maria Van Kelkhoff, the technical leader of the WHO health emergency project, said that the WHO is studying proposals for naming to ensure that no one is dissatisfied with these names
In any case, Van Kelkhoff said that new variants of the virus that evade vaccines and other defenses are the "real threat" to humanity
