Only one strain of Covid-19
variant found in India of
concern, says WHO
Only one strain of a Covid-19 variant first detected in India was
now considered "of concern", World Health Organisation
(WHO) said in its weekly epidemiological update on the
pandemic. The other two strains have been downgraded.
The B.1.617 variant--blamed for the surge in Covid-19 case in
India--is divided into three lineages: B.1.617.1, B.1.617.2 and
B.1.617.3. The UN health agency last month declared the entire
strain a "variant of concern", or VOC. On Tuesday, it said only one
of the sub-lineages deserved that label.
"With updated information, B.1.617.2 remains a VOC and labeled
variant Delta – we continue to observe significantly increased
transmissibility and a growing number of countries reporting
outbreaks associated with this variant," WHO said.
"Further studies into the impact of this variant remain a high
priority for WHO".
B.1.617.1 has been reclassified to a Variant Of Interest (VOI) and
labeled variant Kappa – while also demonstrating increased
transmissibility (in specified locations), global prevalence
appears to be declining. Read More
