Chicago: The spread of sustainable SARS-COV-2 virus has given birth to the Greek alphabet – the naming system used by the World Health Organization (WHO) to track about the new virus mutation that caused Covid-19.
Some have completed the virus in a better way to infect humans or avoid vaccine protection.
Scientists remain focused on Delta, now the dominant variant throughout the world, but traces other people to see what might happen one day.
Delta – Still the dominant Delta variant is first detected in India the most worrying India.
This striking population that is not vaccinated in many countries and has been proven to be able to infect a higher proportion of people who are vaccinated than its predecessor.
WHO classifies Delta as a concerned variant, which means that it has been shown to be able to increase transmission, causing a more severe disease or reducing the benefits of vaccines and maintenance.
According to Shane Retty, a virology at La Jolla Institute for Immunology in San Diego, “Delta’s superpower” is a transmission.
Chinese researchers found that delta infected people carry 1,260 times more viruses in their nose compared to the original version of Coronavirus.
Some research A.S.
Indicates that the viral load on vaccinated individuals infected with delta is equivalent to those who are not vaccinated, but more research is needed.
While the original Coronavirus takes up to seven days to cause symptoms, deltas can cause symptoms of two to three days faster, providing fewer immune systems to respond and install defense.
Lambda – On Wanethe Lambda’s variant has attracted attention as a potential new threat, but this version of Coronavirus, was first identified in Peru in December, seems to receure.
Although cases involving Lambda increased in July, this variant report has fallen globally for the past four weeks, according to data by GISAID, the database that tracks the SARS-COV-2 variant.
WHO classifies lambda as an interesting variant, meaning carrying mutations allegedly causing changes in transmission or causing a more severe disease, but still under investigation.
Lab studies indicate that it has a mutation that holds an antibody induced by vaccines.
MU – One to Watchmu, a variant previously known as B.1.621, was first identified in Colombia in January.
On August 30, which set it as an interesting variant due to several mutations, and set the name of the Greek letter for it.
MU brings the main mutation, including E484K, N501Y and D614G, which has been associated with increased transmission and reducing immune protection.
According to the WHO bulletin published last week, MU has caused several larger outbreaks in South America and Europe.
While the number of genetic sequences identified as MU has fallen below 0.1% globally, MU represents 39% of the variants sorted in Colombia and 13% in Ecuador, places where their prevalence “increased consistently,” who reported.
The global health agency said it continued to monitor MU for changes in South America, especially in areas where it circulated together with Delta variants.
Maria van Kerkhove, head of whom the disease unit appeared, said the circulation of variants decreased globally but needed to be carefully observed.
In the press direction last week, Chief Medical Advisor White Building Dr.
Anthony Fauci said officials A.S.
Witness it, but so far MU is not considered a direct threat.
More on the way? Getting more people who are vaccinated against Covid-19 is very important because large groups of people who are not vaccinated give the virus more opportunities to spread to new variants.
These efforts must be further enhanced to keep the variants from appearing that are not checked among the population of poor countries where very few people have been inoculated, experts said.
Even so, while the vaccine currently prevents severe illness and death, they do not block infection.
This virus is still able to replicate in the nose, even among people who are vaccinated, which can then transmit disease through color droplets and colored Aeros.
To defeat SARS-COV-2 is likely to need a new generation of vaccines that also block transmissions, according to Dr.
Gregory Poland, vaccine developer in the Mayo Clinic.
Until then, Poland and other experts said the world remained vulnerable to the resurrection of the new Coronavirus variant.
