On December 4, Maharashtra detected its first case with new Covid variantB.1.1.529 or Omicron. In the last 26 days, the total number of Omicron cases, which is further transmittable than Delta, the dominant variants during the alternate surge, and also has a advanced eventuality of impunity escape has surged up to 450 in the state as of December 30.
To add to the solicitude, nearly one-third of the samples have been detected with Omicron in Mumbai in the rearmost genome sequencing report, which indicated toward a possible community transmission, contributing in the doubling of Covid-19 cases within 24 hours.
With the leveling of the epidemic wind, the total active Covid-19 cases in Maharashtra dropped to on November 29, which was in May 15,. This gave stopgap of a possible‘ aboriginal’. But in the last one month, the active cases in Maharashtra have surged by 141 – in number – as recorded on December 30.
Scientists have attributed this shaft to Omicron. On November 26, the World Health Organisation declared it as a variant of concern due to its extreme position of contagiousness and capability to shirk people’s impunity carried through the vaccination and once infection with Covid-19.
Omicron is a more transmittable variant than Delta which was formerly a more transmittable variant than Nascence, which was the dominant strain when Delta was first reported,” said Dr Lancelot Pinto, epidemiologist and pulmonologist, Hinduja Hospital.
Omicron also has a briskly incubation period ( gap of time between someone getting exposed to the contagion and also showing symptoms) than Delta variants. This is also being reflected at the 24 hours daily doubling rate in Mumbai. On December 29, the megacity reported diurnal Covid-19 cases which surged to the coming day.
Still, reports across the globe show that hospitalisation rates in Omicron compared with the Delta variant is less, including duration of sanitarium stay and the need for supplemental oxygen remedy.
“ The dominant Covid variant, Omicron, has different complaint characteristics as compared to Nascence or Delta variants. Transnational studies from South Africa or the United Kingdom indicate that the contagion remains in the upper airways and does n’t access lung towel or beget clotting diseases like its earlier variants — Delta or Alpha. Hence, Omicron is causing a lot of upper respiratory symptoms similar as cold and flu but not major lung complications. As a reason, we’re observing a softened, mild interpretation of the contagion which is largely contagious,” said Dr Hemlata Arora, elderly adviser, contagious conditions, Nanavati Hospital.
