Only one strain of the coronavirus variant detected for the first time in India, is still considered “worrying“And the other two have been degraded, according to the World Health Organization (WHO). Variant B.1.617, considered partially responsible for the outbreak of the pandemic in the country, has spread to more than 50 territories, with three different lineages.
The WHO stated last month that the entire variant was “worrying”, But this Tuesday he clarified that only one lineage should be considered as such, the so-called Delta.
“It has become apparent that more public health risks are currently associated with B.1.617.2, while lower transmission rates have been observed with the other lineages.”, Reported the WHO in its weekly epidemiological update on the pandemic.
B.1.617.2 remains of concern, along with three other variants of the virus, considered more dangerous than the original version because they are more contagious, lethal, or because vaccines may not protect against them.
The WHO on Monday assigned Greek letters to the scientific names of the various variants such as Alpha, Beta, Gamma or Delta for the case of B.1.617. It’s about avoiding names “stigmatizing and discriminatory”For the countries and territories where they have appeared.
“We continue to see a marked increase in transmissibility and a growing number of countries reporting outbreaks linked to this variant”, Affirms the WHO, which considers “priority” carry out “new studies”About its impact.
A new hybrid variant, reported on Saturday by Vietnam’s health authorities, appears to be a variation of Delta, reported on Tuesday Dr. Maria Van Kerkhove, technical manager of the fight against COVID-19 in the organization.
“We know that B.1.617.2 has increased transmissibility, which means that it can be spread more easily between people”, He stressed.
The lineage B.1.617.1 was downgraded to the category of “variant of interest”And was christened Kappa.
Regarding B.1.617.3, the WHO He no longer finds it interesting and has not assigned it a Greek letter.
