Covid-19 cases continuously rising in India for the past few weeks, and the new Covid variant Arcturus, or XBB.1.16 as it is clinically referred to, is responsible for the spike, according to World Health Organisation (WHO). As per the global health body, the strain has been found in coronavirus cases across at least 22 countries, including Singapore, Australia, the UK and the US.
XBB.1.16, or the Arcturus variant, that was first detected in January, could be 1.2 times more infectious than other Omicron variants, a report by Hindustan Times said quoting a study by the University of Tokyo published on the biology research website bioRxiv.
However, the latest Covid surge is not alarming as the lethality of the virus has been reduced significantly, a top health ministry source said. The official explained that India’s apex medical research agency, the Indian Council of Medical Research (ICMR), has isolated the XBB.1.16 omicron subvariant and assessed the vaccine efficiency.
“The XBB subvariant of Covid has been isolated, assessment of vaccine efficiency has been done. This variant is not fatal,” said the official.
Origin of Arcturus
XBB.1.16 was first detected in SARS-CoV-2 sequences from India, a recombinant lineage of Covid, XBB.1.16 is a descendent of the XBB lineage. The preliminary data on the virus suggest that XBB.1.16 has a higher growth advantage over other SARS-CoV-2 lineages that are currently circulating including the XBB.1.5 lineage.
