New study confirms community transmission of Omicron in Delhi
India TodayIn a first, an Indian study confirmed that the emergence of the omicron variant of SARS-CoV-2 caused community spread in Delhi as early as December 2021. In the study led by he Institute of Liver and Biliary Sciences in Delhi, analysis of Covid positive samples provides the evidence of community transmission of Omicron with significantly increased breakthrough infections, decreased hospitalization rates, and lower rate of symptomatic infections among individuals with high seropositivity against SARS-CoV-2 infections. Dr Ekta Gupta, Professor and Head, Department of Clinical Virology Institute of Liver and Biliary Sciences, who is the corresponding author of the study said, “The first two cases of Omicron were detected during the first week of December with travel history from South Africa. At this rate, it is expected that from January 2022, there is 100% infection due to omicron variant in Delhi.” NO TRAVEL HISTORY The history of international travel was documented in 19 cases- South Africa,UK, UAE, USA and Canada while thirteen cases were the contacts of such travellers. This shift of sub-lineage in Omicron was also documented in Australia among 300 cases with travel history to South Africa.” The authors further said, “We observed young adults and males were infected more in comparison to children and the elderly population, which could be because of more socialising habits and close connections than other mentioned groups.
